+ # Attention Masks and Pad Tokens in Transformer Generation: Research Questions
2
+
3
+ ## Core Problem Statement
4
+
5
+ When running transformer models (specifically Llama-3.2-1B-Instruct) for text generation, we encounter warnings about missing attention masks and pad tokens, even for single input sequences. This leads to inconsistent generation outputs despite identical inputs.
6
+
7
+ ### Warning Messages Observed
8
+ ```
9
+ The attention mask and the pad token id were not set. As a consequence, you may observe unexpected behavior. Please pass your input's `attention_mask` to obtain reliable results.
10
+ Setting `pad_token_id` to `eos_token_id`:128001 for open-end generation.
11
+ The attention mask is not set and cannot be inferred from input because pad token is same as eos token.
12
+ ```
13
+
14
+ ## Key Research Questions
15
+
16
+ ### 1. Why do single inputs require attention masks?
17
+ **Initial Assumption**: Single sequences without padding shouldn't need attention masks.
18
+ **Observed Reality**: Even single inputs show different generation outputs when attention masks are missing.
19
+
20
+ ### 2. What is the relationship between pad tokens and attention masks?
21
+ **Question**: How do pad_token_id and attention_mask work together in the generation process?
22
+
23
+ ### 3. Why does pad_token_id = eos_token_id cause issues?
24
+ **Specific Issue**: When padding token equals end-of-sequence token, what ambiguity does this create?
25
+
26
+ ## Code Analysis
27
+
28
+ ### Current Implementation (Problematic)
29
+ ```python
30
+ def chat_current(system_prompt: str, user_prompt: str) -> str:
31
+ messages = [
32
+ {"role": "system", "content": system_prompt},
33
+ {"role": "user", "content": user_prompt},
34
+ ]
35
+
36
+ # Only returns input_ids tensor
37
+ input_ids = tok.apply_chat_template(
38
+ messages,
39
+ add_generation_prompt=True,
40
+ return_tensors="pt"
41
+ ).to(lm.device)
42
+
43
+ with torch.inference_mode():
44
+ output_ids = lm.generate(
45
+ input_ids, # Missing: attention_mask, pad_token_id
46
+ max_new_tokens=2048,
47
+ do_sample=True,
48
+ temperature=0.2,
49
+ repetition_penalty=1.1,
50
+ top_k=100,
51
+ top_p=0.95,
52
+ )
53
+
54
+ return tok.decode(output_ids[0][input_ids.shape[-1]:], skip_special_tokens=True)
55
+ ```
56
+
57
+ ### Fixed Implementation
58
+ ```python
59
+ def chat_fixed(system_prompt: str, user_prompt: str) -> str:
60
+ messages = [
61
+ {"role": "system", "content": system_prompt},
62
+ {"role": "user", "content": user_prompt},
63
+ ]
64
+
65
+ # Returns dictionary with input_ids AND attention_mask
66
+ inputs = tok.apply_chat_template(
67
+ messages,
68
+ add_generation_prompt=True,
69
+ return_tensors="pt",
70
+ return_dict=True # KEY CHANGE: Get both components
71
+ )
72
+
73
+ input_ids = inputs["input_ids"].to(lm.device)
74
+ attention_mask = inputs["attention_mask"].to(lm.device)
75
+
76
+ with torch.inference_mode():
77
+ output_ids = lm.generate(
78
+ input_ids=input_ids,
79
+ attention_mask=attention_mask, # Explicit attention guidance
80
+ pad_token_id=tok.eos_token_id, # Explicit pad token
81
+ max_new_tokens=2048,
82
+ do_sample=True,
83
+ temperature=0.2,
84
+ repetition_penalty=1.1,
85
+ top_k=100,
86
+ top_p=0.95,
87
+ )
88
+
89
+ return tok.decode(output_ids[0][input_ids.shape[-1]:], skip_special_tokens=True)
90
+ ```
91
+
92
+ ### Model and Tokenizer Setup
93
+ ```python
94
+ model_name = "models/Llama-3.2-1B-Instruct"
95
+ tok = AutoTokenizer.from_pretrained(model_name)
96
+ # Critical: Set pad token if not available
97
+ if tok.pad_token is None:
98
+ tok.pad_token = tok.eos_token
99
+
100
+ lm = AutoModelForCausalLM.from_pretrained(
101
+ model_name,
102
+ torch_dtype=torch.bfloat16,
103
+ device_map="cuda",
104
+ ).eval()
105
+ ```
106
+
107
+ ## Observed Behavioral Differences
108
+
109
+ ### Input Structure Analysis
110
+ ```python
111
+ # Single input contains multiple components:
112
+ messages = [
113
+ {"role": "system", "content": "You are a helpful assistant..."},
114
+ {"role": "user", "content": "What is the capital of France?"},
115
+ ]
116
+
117
+ # After apply_chat_template, becomes token sequence:
118
+ # [system_tokens, user_tokens, assistant_start_token]
119
+ ```
120
+
121
+ ## Technical Hypotheses for Investigation
122
+
123
+ ### Hypothesis 1: Internal Masking Ambiguity
124
+ When attention_mask is missing, the model cannot distinguish between:
125
+ - Real input tokens that should influence generation
126
+ - Structural tokens (system prompts, role markers)
127
+ - Token boundaries between different message roles
128
+
129
+ ### Hypothesis 2: EOS Token Dual Purpose Confusion
130
+ When `pad_token_id == eos_token_id`, the model faces ambiguity:
131
+ ```python
132
+ # Same token (128001) serves dual purposes:
133
+ # 1. End of sequence marker
134
+ # 2. Padding token for batch processing
135
+ # Model cannot infer which purpose applies in context
136
+ ```
137
+
138
+ ### Hypothesis 3: Autoregressive Generation Context Boundary Issues
139
+ During generation, model needs to know:
140
+ - Which input tokens provide valid context for next token prediction
141
+ - Where the "prompt" ends and "generation" begins
142
+ - How to weight attention across different input components
143
+
144
+ ## Research Objectives
145
+
146
+ ### Primary Questions
147
+ 1. **Mechanism Analysis**: How exactly does missing attention_mask affect the internal attention computation?
148
+ 2. **Consistency Impact**: Why do identical inputs produce different outputs without proper masking?
149
+ 3. **Single vs Batch Behavior**: What differences exist between single sequence and batched sequence processing?
150
+
151
+ ### Secondary Questions
152
+ 1. **Model-Specific Behavior**: Do different transformer architectures handle missing attention masks differently?
153
+ 2. **Generation Parameter Interaction**: How do attention mask issues interact with sampling parameters (temperature, top_p, etc.)?
154
+ 3. **Performance Impact**: What computational overhead does proper attention masking add?
155
+
156
+ ## Key Technical Areas for Deep Research
157
+
158
+ ### Attention Mechanism Internals
159
+ - How attention weights are computed with/without explicit masks
160
+ - Impact on multi-head attention distributions
161
+ - Interaction with causal masking in autoregressive models
162
+
163
+ ### Tokenizer Behavior
164
+ - How `apply_chat_template` constructs input sequences
165
+ - Default attention mask generation behavior
166
+ - Role of special tokens in attention computation
167
+
168
+ ### Generation Process
169
+ - How `model.generate()` handles missing parameters
170
+ - Internal assumptions and fallback behaviors
171
+ - Impact on sampling and beam search algorithms
172
+
173
+ ## Expected Research Outcomes
174
+
175
+ Understanding of:
176
+ 1. Exact mechanism causing output inconsistency
177
+ 2. Best practices for single sequence generation
178
+ 3. Relationship between attention masking and generation quality
179
+ 4. Guidelines for production transformer deployment

+ ## Model Information
223
+
224
+ The Llama 3.2 collection of multilingual large language models (LLMs) is a collection of pretrained and instruction-tuned generative models in 1B and 3B sizes (text in/text out). The Llama 3.2 instruction-tuned text only models are optimized for multilingual dialogue use cases, including agentic retrieval and summarization tasks. They outperform many of the available open source and closed chat models on common industry benchmarks.
225
+
226
+ **Model Developer:** Meta
227
+
228
+ **Model Architecture:** Llama 3.2 is an auto-regressive language model that uses an optimized transformer architecture. The tuned versions use supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to align with human preferences for helpfulness and safety.

237
+ **Supported Languages:** English, German, French, Italian, Portuguese, Hindi, Spanish, and Thai are officially supported. Llama 3.2 has been trained on a broader collection of languages than these 8 supported languages. Developers may fine-tune Llama 3.2 models for languages beyond these supported languages, provided they comply with the Llama 3.2 Community License and the Acceptable Use Policy. Developers are always expected to ensure that their deployments, including those that involve additional languages, are completed safely and responsibly.
238
+
239
+ **Llama 3.2 Model Family:** Token counts refer to pretraining data only. All model versions use Grouped-Query Attention (GQA) for improved inference scalability.
240
+
241
+ **Model Release Date:** Sept 25, 2024
242
+
243
+ **Status:** This is a static model trained on an offline dataset. Future versions may be released that improve model capabilities and safety.
244
+
245
+ **License:** Use of Llama 3.2 is governed by the [Llama 3.2 Community License](https://github.com/meta-llama/llama-models/blob/main/models/llama3_2/LICENSE) (a custom, commercial license agreement).
246
+
247
+ **Feedback:** Instructions on how to provide feedback or comments on the model can be found in the Llama Models [README](https://github.com/meta-llama/llama-models/blob/main/README.md). For more technical information about generation parameters and recipes for how to use Llama 3.2 in applications, please go [here](https://github.com/meta-llama/llama-recipes).
248
+
249
+ ## Intended Use
250
+
251
+ **Intended Use Cases:** Llama 3.2 is intended for commercial and research use in multiple languages. Instruction tuned text only models are intended for assistant-like chat and agentic applications like knowledge retrieval and summarization, mobile AI powered writing assistants and query and prompt rewriting. Pretrained models can be adapted for a variety of additional natural language generation tasks. Similarly, quantized models can be adapted for a variety of on-device use-cases with limited compute resources.

Use in any other way that is prohibited by the Acceptable Use Policy and Llama 3.2 Community License. Use in languages beyond those explicitly referenced as supported in this model card.
254
+
255
+ ## How to use
256
+
257
+ This repository contains two versions of Llama-3.2-1B-Instruct, for use with transformers and with the original `llama` codebase.
258
+
259
+ ### Use with transformers
260
+
261
+ Starting with `transformers >= 4.43.0` onward, you can run conversational inference using the Transformers `pipeline` abstraction or by leveraging the Auto classes with the `generate()` function.
262
+
263
+ Make sure to update your transformers installation via `pip install --upgrade transformers`.
264
+
265
+ ```python
266
+ import torch
267
+ from transformers import pipeline
268
+
269
+ model_id = "meta-llama/Llama-3.2-1B-Instruct"
270
+ pipe = pipeline(
271
+ "text-generation",
272
+ model=model_id,
273
+ torch_dtype=torch.bfloat16,
274
+ device_map="auto",
275
+ )
276
+ messages = [
277
+ {"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
278
+ {"role": "user", "content": "Who are you?"},
279
+ ]
280
+ outputs = pipe(
281
+ messages,
282
+ max_new_tokens=256,
283
+ )
284
+ print(outputs[0]["generated_text"][-1])
285
+ ```
286
+
287
+ Note: You can also find detailed recipes on how to use the model locally, with `torch.compile()`, assisted generations, quantised and more at [`huggingface-llama-recipes`](https://github.com/huggingface/huggingface-llama-recipes)
288
+
289
+ ### Use with `llama`
290
+
291
+ Please, follow the instructions in the [repository](https://github.com/meta-llama/llama)
292
+
293
+ To download Original checkpoints, see the example command below leveraging `huggingface-cli`:
294
+
295
+ ```
296
+ huggingface-cli download meta-llama/Llama-3.2-1B-Instruct --include "original/*" --local-dir Llama-3.2-1B-Instruct
297
+ ```
298
+
299
+ ## Hardware and Software
300
+
301
+ **Training Factors:** We used custom training libraries, Meta's custom built GPU cluster, and production infrastructure for pretraining. Fine-tuning, quantization, annotation, and evaluation were also performed on production infrastructure.
302
+
303
+ **Training Energy Use:** Training utilized a cumulative of **916k** GPU hours of computation on H100-80GB (TDP of 700W) type hardware, per the table below. Training time is the total GPU time required for training each model and power consumption is the peak power capacity per GPU device used, adjusted for power usage efficiency.
304
+
305
+ **Training Greenhouse Gas Emissions:** Estimated total location-based greenhouse gas emissions were **240** tons CO2eq for training. Since 2020, Meta has maintained net zero greenhouse gas emissions in its global operations and matched 100% of its electricity use with renewable energy; therefore, the total market-based greenhouse gas emissions for training were 0 tons CO2eq.
306
+
307
+ | | Training Time (GPU hours) | Logit Generation Time (GPU Hours) | Training Power Consumption (W) | Training Location-Based Greenhouse Gas Emissions (tons CO2eq) | Training Market-Based Greenhouse Gas Emissions (tons CO2eq) |

315
+ | Total | 833k | 86k | | 240 | 0 |
316
+
317
+ \*\* The location-based CO2e emissions of Llama 3.2 1B SpinQuant and Llama 3.2 3B SpinQuant are less than 0.001 metric tonnes each. This is due to the minimal training GPU hours that are required.
318
+
319
+ The methodology used to determine training energy use and greenhouse gas emissions can be found [here](https://arxiv.org/pdf/2204.05149). Since Meta is openly releasing these models, the training energy use and greenhouse gas emissions will not be incurred by others.
320
+
321
+ ## Training Data
322
+
323
+ **Overview:** Llama 3.2 was pretrained on up to 9 trillion tokens of data from publicly available sources. For the 1B and 3B Llama 3.2 models, we incorporated logits from the Llama 3.1 8B and 70B models into the pretraining stage of the model development, where outputs (logits) from these larger models were used as token-level targets. Knowledge distillation was used after pruning to recover performance. In post-training we used a similar recipe as Llama 3.1 and produced final chat models by doing several rounds of alignment on top of the pre-trained model. Each round involved Supervised Fine-Tuning (SFT), Rejection Sampling (RS), and Direct Preference Optimization (DPO).
324
+
325
+ **Data Freshness:** The pretraining data has a cutoff of December 2023\.
326
+
327
+ ## Quantization
328
+
329
+ ### Quantization Scheme
330
+
331
+ We designed the current quantization scheme with the [PyTorch’s ExecuTorch](https://github.com/pytorch/executorch) inference framework and Arm CPU backend in mind, taking into account metrics including model quality, prefill/decoding speed, and memory footprint. Our quantization scheme involves three parts:
332
+ - All linear layers in all transformer blocks are quantized to a 4-bit groupwise scheme (with a group size of 32) for weights and 8-bit per-token dynamic quantization for activations.
333
+ - The classification layer is quantized to 8-bit per-channel for weight and 8-bit per token dynamic quantization for activation.
334
+ - Similar to classification layer, an 8-bit per channel quantization is used for embedding layer.
335
+
336
+
337
+ ### Quantization-Aware Training and LoRA
338
+
339
+ The quantization-aware training (QAT) with low-rank adaptation (LoRA) models went through only post-training stages, using the same data as the full precision models. To initialize QAT, we utilize BF16 Llama 3.2 model checkpoints obtained after supervised fine-tuning (SFT) and perform an additional full round of SFT training with QAT. We then freeze the backbone of the QAT model and perform another round of SFT with LoRA adaptors applied to all layers within the transformer block. Meanwhile, the LoRA adaptors' weights and activations are maintained in BF16. Because our approach is similar to QLoRA of Dettmers et al., (2023) (i.e., quantization followed by LoRA adapters), we refer this method as QLoRA. Finally, we fine-tune the resulting model (both backbone and LoRA adaptors) using direct preference optimization (DPO).
340
+
341
+ ### SpinQuant
342
+
343
+ [SpinQuant](https://arxiv.org/abs/2405.16406) was applied, together with generative post-training quantization (GPTQ). For the SpinQuant rotation matrix fine-tuning, we optimized for 100 iterations, using 800 samples with sequence-length 2048 from the WikiText 2 dataset. For GPTQ, we used 128 samples from the same dataset with the same sequence-length.

422
+ ## Responsibility & Safety
423
+
424
+ As part of our Responsible release approach, we followed a three-pronged strategy to managing trust & safety risks:
425
+
426
+ 1. Enable developers to deploy helpful, safe and flexible experiences for their target audience and for the use cases supported by Llama
427
+ 2. Protect developers against adversarial users aiming to exploit Llama capabilities to potentially cause harm
428
+ 3. Provide protections for the community to help prevent the misuse of our models
429
+
430
+ ### Responsible Deployment
431
+
432
+ **Approach:** Llama is a foundational technology designed to be used in a variety of use cases. Examples on how Meta’s Llama models have been responsibly deployed can be found in our [Community Stories webpage](https://llama.meta.com/community-stories/). Our approach is to build the most helpful models, enabling the world to benefit from the technology power, by aligning our model safety for generic use cases and addressing a standard set of harms. Developers are then in the driver’s seat to tailor safety for their use cases, defining their own policies and deploying the models with the necessary safeguards in their Llama systems. Llama 3.2 was developed following the best practices outlined in our [Responsible Use Guide](https://llama.meta.com/responsible-use-guide/).
433
+
434
+ #### Llama 3.2 Instruct
435
+
436
+ **Objective:** Our main objectives for conducting safety fine-tuning are to provide the research community with a valuable resource for studying the robustness of safety fine-tuning, as well as to offer developers a readily available, safe, and powerful model for various applications to reduce the developer workload to deploy safe AI systems. We implemented the same set of safety mitigations as in Llama 3, and you can learn more about these in the Llama 3 [paper](https://ai.meta.com/research/publications/the-llama-3-herd-of-models/).
437
+
438
+ **Fine-Tuning Data:** We employ a multi-faceted approach to data collection, combining human-generated data from our vendors with synthetic data to mitigate potential safety risks. We’ve developed many large language model (LLM)-based classifiers that enable us to thoughtfully select high-quality prompts and responses, enhancing data quality control.
439
+
440
+ **Refusals and Tone:** Building on the work we started with Llama 3, we put a great emphasis on model refusals to benign prompts as well as refusal tone. We included both borderline and adversarial prompts in our safety data strategy, and modified our safety data responses to follow tone guidelines.
441
+
442
+ #### Llama 3.2 Systems
443
+
444
+ **Safety as a System:** Large language models, including Llama 3.2, **are not designed to be deployed in isolation** but instead should be deployed as part of an overall AI system with additional safety guardrails as required. Developers are expected to deploy system safeguards when building agentic systems. Safeguards are key to achieve the right helpfulness-safety alignment as well as mitigating safety and security risks inherent to the system and any integration of the model or system with external tools. As part of our responsible release approach, we provide the community with [safeguards](https://llama.meta.com/trust-and-safety/) that developers should deploy with Llama models or other LLMs, including Llama Guard, Prompt Guard and Code Shield. All our [reference implementations](https://github.com/meta-llama/llama-agentic-system) demos contain these safeguards by default so developers can benefit from system-level safety out-of-the-box.
445
+
446
+ ### New Capabilities and Use Cases
447
+
448
+ **Technological Advancement:** Llama releases usually introduce new capabilities that require specific considerations in addition to the best practices that generally apply across all Generative AI use cases. For prior release capabilities also supported by Llama 3.2, see [Llama 3.1 Model Card](https://github.com/meta-llama/llama-models/blob/main/models/llama3_1/MODEL_CARD.md), as the same considerations apply here as well.
449
+
450
+ **Constrained Environments:** Llama 3.2 1B and 3B models are expected to be deployed in highly constrained environments, such as mobile devices. LLM Systems using smaller models will have a different alignment profile and safety/helpfulness tradeoff than more complex, larger systems. Developers should ensure the safety of their system meets the requirements of their use case. We recommend using lighter system safeguards for such use cases, like Llama Guard 3-1B or its mobile-optimized version.
451
+
452
+ ### Evaluations
453
+
454
+ **Scaled Evaluations:** We built dedicated, adversarial evaluation datasets and evaluated systems composed of Llama models and Purple Llama safeguards to filter input prompt and output response. It is important to evaluate applications in context, and we recommend building dedicated evaluation dataset for your use case.
455
+
456
+ **Red Teaming:** We conducted recurring red teaming exercises with the goal of discovering risks via adversarial prompting and we used the learnings to improve our benchmarks and safety tuning datasets. We partnered early with subject-matter experts in critical risk areas to understand the nature of these real-world harms and how such models may lead to unintended harm for society. Based on these conversations, we derived a set of adversarial goals for the red team to attempt to achieve, such as extracting harmful information or reprogramming the model to act in a potentially harmful capacity. The red team consisted of experts in cybersecurity, adversarial machine learning, responsible AI, and integrity in addition to multilingual content specialists with background in integrity issues in specific geographic markets.
457
+
458
+ ### Critical Risks
459
+
460
+ In addition to our safety work above, we took extra care on measuring and/or mitigating the following critical risk areas:
461
+
462
+ **1\. CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive Weapons):** Llama 3.2 1B and 3B models are smaller and less capable derivatives of Llama 3.1. For Llama 3.1 70B and 405B, to assess risks related to proliferation of chemical and biological weapons, we performed uplift testing designed to assess whether use of Llama 3.1 models could meaningfully increase the capabilities of malicious actors to plan or carry out attacks using these types of weapons and have determined that such testing also applies to the smaller 1B and 3B models.
463
+
464
+ **2\. Child Safety:** Child Safety risk assessments were conducted using a team of experts, to assess the model’s capability to produce outputs that could result in Child Safety risks and inform on any necessary and appropriate risk mitigations via fine tuning. We leveraged those expert red teaming sessions to expand the coverage of our evaluation benchmarks through Llama 3 model development. For Llama 3, we conducted new in-depth sessions using objective based methodologies to assess the model risks along multiple attack vectors including the additional languages Llama 3 is trained on. We also partnered with content specialists to perform red teaming exercises assessing potentially violating content while taking account of market specific nuances or experiences.
465
+
466
+ **3\. Cyber Attacks:** For Llama 3.1 405B, our cyber attack uplift study investigated whether LLMs can enhance human capabilities in hacking tasks, both in terms of skill level and speed.
467
+ Our attack automation study focused on evaluating the capabilities of LLMs when used as autonomous agents in cyber offensive operations, specifically in the context of ransomware attacks. This evaluation was distinct from previous studies that considered LLMs as interactive assistants. The primary objective was to assess whether these models could effectively function as independent agents in executing complex cyber-attacks without human intervention. Because Llama 3.2’s 1B and 3B models are smaller and less capable models than Llama 3.1 405B, we broadly believe that the testing conducted for the 405B model also applies to Llama 3.2 models.
468
+
469
+ ### Community
470
+
471
+ **Industry Partnerships:** Generative AI safety requires expertise and tooling, and we believe in the strength of the open community to accelerate its progress. We are active members of open consortiums, including the AI Alliance, Partnership on AI and MLCommons, actively contributing to safety standardization and transparency. We encourage the community to adopt taxonomies like the MLCommons Proof of Concept evaluation to facilitate collaboration and transparency on safety and content evaluations. Our Purple Llama tools are open sourced for the community to use and widely distributed across ecosystem partners including cloud service providers. We encourage community contributions to our [Github repository](https://github.com/meta-llama/PurpleLlama).
472
+
473
+ **Grants:** We also set up the [Llama Impact Grants](https://llama.meta.com/llama-impact-grants/) program to identify and support the most compelling applications of Meta’s Llama model for societal benefit across three categories: education, climate and open innovation. The 20 finalists from the hundreds of applications can be found [here](https://llama.meta.com/llama-impact-grants/#finalists).
474
+
475
+ **Reporting:** Finally, we put in place a set of resources including an [output reporting mechanism](https://developers.facebook.com/llama_output_feedback) and [bug bounty program](https://www.facebook.com/whitehat) to continuously improve the Llama technology with the help of the community.
476
+
477
+ ## Ethical Considerations and Limitations
478
+
479
+ **Values:** The core values of Llama 3.2 are openness, inclusivity and helpfulness. It is meant to serve everyone, and to work for a wide range of use cases. It is thus designed to be accessible to people across many different backgrounds, experiences and perspectives. Llama 3.2 addresses users and their needs as they are, without insertion unnecessary judgment or normativity, while reflecting the understanding that even content that may appear problematic in some cases can serve valuable purposes in others. It respects the dignity and autonomy of all users, especially in terms of the values of free thought and expression that power innovation and progress.
480
+
481
+ **Testing:** Llama 3.2 is a new technology, and like any new technology, there are risks associated with its use. Testing conducted to date has not covered, nor could it cover, all scenarios. For these reasons, as with all LLMs, Llama 3.2’s potential outputs cannot be predicted in advance, and the model may in some instances produce inaccurate, biased or other objectionable responses to user prompts. Therefore, before deploying any applications of Llama 3.2 models, developers should perform safety testing and tuning tailored to their specific applications of the model. Please refer to available resources including our [Responsible Use Guide](https://llama.meta.com/responsible-use-guide), [Trust and Safety](https://llama.meta.com/trust-and-safety/) solutions, and other [resources](https://llama.meta.com/docs/get-started/) to learn more about responsible development.

+ "Object" form shall mean any form resulting from mechanical
32
+ transformation or translation of a Source form, including but
33
+ not limited to compiled object code, generated documentation,
34
+ and conversions to other media types.
35
+
36
+ "Work" shall mean the work of authorship, whether in Source or
37
+ Object form, made available under the License, as indicated by a
38
+ copyright notice that is included in or attached to the work
39
+ (an example is provided in the Appendix below).
40
+
41
+ "Derivative Works" shall mean any work, whether in Source or Object
42
+ form, that is based on (or derived from) the Work and for which the
43
+ editorial revisions, annotations, elaborations, or other modifications
44
+ represent, as a whole, an original work of authorship. For the purposes
45
+ of this License, Derivative Works shall not include works that remain
46
+ separable from, or merely link (or bind by name) to the interfaces of,
47
+ the Work and Derivative Works thereof.
48
+
49
+ "Contribution" shall mean any work of authorship, including

68
+ this License, each Contributor hereby grants to You a perpetual,
69
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable

80
+ by such Contributor that are necessarily infringed by their
81
+ Contribution(s) alone or by combination of their Contribution(s)
82
+ with the Work to which such Contribution(s) was submitted. If You
83
+ institute patent litigation against any entity (including a
84
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
85
+ or a Contribution incorporated within the Work constitutes direct
86
+ or contributory patent infringement, then any patent licenses
87
+ granted to You under this License for that Work shall terminate
88
+ as of the date such litigation is filed.

166
+ 9. Accepting Warranty or Additional Liability. While redistributing

14
+ ## VibeVoice: A Frontier Open-Source Text-to-Speech Model
15
+
16
+ VibeVoice is a novel framework designed for generating expressive, long-form, multi-speaker conversational audio, such as podcasts, from text. It addresses significant challenges in traditional Text-to-Speech (TTS) systems, particularly in scalability, speaker consistency, and natural turn-taking.
17
+
18
+ A core innovation of VibeVoice is its use of continuous speech tokenizers (Acoustic and Semantic) operating at an ultra-low frame rate of 7.5 Hz. These tokenizers efficiently preserve audio fidelity while significantly boosting computational efficiency for processing long sequences. VibeVoice employs a next-token diffusion framework, leveraging a Large Language Model (LLM) to understand textual context and dialogue flow, and a diffusion head to generate high-fidelity acoustic details.
19
+
20
+ The model can synthesize speech up to **90 minutes** long with up to **4 distinct speakers**, surpassing the typical 1-2 speaker limits of many prior models.

32
+ ## Training Details
33
+ Transformer-based Large Language Model (LLM) integrated with specialized acoustic and semantic tokenizers and a diffusion-based decoding head.
34
+ - LLM: [Qwen2.5-1.5B](https://huggingface.co/Qwen/Qwen2.5-1.5B) for this release.
35
+ - Tokenizers:
36
+ - Acoustic Tokenizer: Based on a σ-VAE variant (proposed in [LatentLM](https://arxiv.org/pdf/2412.08635)), with a mirror-symmetric encoder-decoder structure featuring 7 stages of modified Transformer blocks. Achieves 3200x downsampling from 24kHz input. Encoder/decoder components are ~340M parameters each.
37
+ - Semantic Tokenizer: Encoder mirrors the Acoustic Tokenizer's architecture (without VAE components). Trained with an ASR proxy task.
38
+ - Diffusion Head: Lightweight module (4 layers, ~123M parameters) conditioned on LLM hidden states. Predicts acoustic VAE features using a Denoising Diffusion Probabilistic Models (DDPM) process. Uses Classifier-Free Guidance (CFG) and DPM-Solver (and variants) during inference.
39
+ - Context Length: Trained with a curriculum increasing up to 65,536 tokens.
40
+ - Training Stages:
41
+ - Tokenizer Pre-training: Acoustic and Semantic tokenizers are pre-trained separately.
42
+ - VibeVoice Training: Pre-trained tokenizers are frozen; only the LLM and diffusion head parameters are trained. A curriculum learning strategy is used for input sequence length (4k -> 16K -> 32K -> 64K). Text tokenizer not explicitly specified, but the LLM (Qwen2.5) typically uses its own. Audio is "tokenized" via the acoustic and semantic tokenizers.

52
+ ## Installation and Usage
53
+
54
+ Please refer to [GitHub README](https://github.com/microsoft/VibeVoice?tab=readme-ov-file#installation)
55
+
56
+ ## Responsible Usage
57
+ ### Direct intended uses
58
+ The VibeVoice model is limited to research purpose use exploring highly realistic audio dialogue generation detailed in the [tech report](https://arxiv.org/pdf/2508.19205).
59
+
60
+ ### Out-of-scope uses
61
+ Use in any manner that violates applicable laws or regulations (including trade compliance laws). Use in any other way that is prohibited by MIT License. Use to generate any text transcript. Furthermore, this release is not intended or licensed for any of the following scenarios:
62
+
63
+ - Voice impersonation without explicit, recorded consent – cloning a real individual’s voice for satire, advertising, ransom, social‑engineering, or authentication bypass.
64
+ - Disinformation or impersonation – creating audio presented as genuine recordings of real people or events.
65
+ - Real‑time or low‑latency voice conversion – telephone or video‑conference “live deep‑fake” applications.
66
+ - Unsupported language – the model is trained only on English and Chinese data; outputs in other languages are unsupported and may be unintelligible or offensive.
67
+ - Generation of background ambience, Foley, or music – VibeVoice is speech‑only and will not produce coherent non‑speech audio.
68
+
69
+
70
+ ## Risks and limitations
71
+ While efforts have been made to optimize it through various techniques, it may still produce outputs that are unexpected, biased, or inaccurate. VibeVoice inherits any biases, errors, or omissions produced by its base model (specifically, Qwen2.5 1.5b in this release).
72
+ Potential for Deepfakes and Disinformation: High-quality synthetic speech can be misused to create convincing fake audio content for impersonation, fraud, or spreading disinformation. Users must ensure transcripts are reliable, check content accuracy, and avoid using generated content in misleading ways. Users are expected to use the generated content and to deploy the models in a lawful manner, in full compliance with all applicable laws and regulations in the relevant jurisdictions. It is best practice to disclose the use of AI when sharing AI-generated content.
73
+ English and Chinese only: Transcripts in language other than English or Chinese may result in unexpected audio outputs.
74
+ Non-Speech Audio: The model focuses solely on speech synthesis and does not handle background noise, music, or other sound effects.
75
+ Overlapping Speech: The current model does not explicitly model or generate overlapping speech segments in conversations.
76
+
77
+
78
+ ## Recommendations
79
+ We do not recommend using VibeVoice in commercial or real-world applications without further testing and development. This model is intended for research and development purposes only. Please use responsibly.
80
+
81
+ To mitigate the risks of misuse, we have:
82
+ Embedded an audible disclaimer (e.g. “This segment was generated by AI”) automatically into every synthesized audio file.
83
+ Added an imperceptible watermark to generated audio so third parties can verify VibeVoice provenance. Please see contact information at the end of this model card.
84
+ Logged inference requests (hashed) for abuse pattern detection and publishing aggregated statistics quarterly.
85
+ Users are responsible for sourcing their datasets legally and ethically. This may include securing appropriate rights and/or anonymizing data prior to use with VibeVoice. Users are reminded to be mindful of data privacy concerns.
86
+
87
+
88
+ ## Contact
89
+ This project was conducted by members of Microsoft Research. We welcome feedback and collaboration from our audience. If you have suggestions, questions, or observe unexpected/offensive behavior in our technology, please contact us at VibeVoice@microsoft.com.
90
+ If the team receives reports of undesired behavior or identifies issues independently, we will update this repository with appropriate mitigations.

+ - `True`表示model代码实现从`remote_code`处加载,`remote_code`指定`model`具体代码的位置(例如,当前目录下的`model.py`),支持绝对路径与相对路径,以及网络url。
130
+ - `False`表示,model代码实现为 [FunASR](https://github.com/modelscope/FunASR) 内部集成版本,此时修改当前目录下的`model.py`不会生效,因为加载的是funasr内部版本,模型代码[点击查看](https://github.com/modelscope/FunASR/tree/main/funasr/models/sense_voice)。
131
+ - `vad_model`:表示开启VAD,VAD的作用是将长音频切割成短音频,此时推理耗时包括了VAD与SenseVoice总耗时,为链路耗时,如果需要单独测试SenseVoice模型耗时,可以关闭VAD模型。
132
+ - `vad_kwargs`:表示VAD模型配置,`max_single_segment_time`: 表示`vad_model`最大切割音频时长, 单位是毫秒ms。
133
+ - `use_itn`:输出结果中是否包含标点与逆文本正则化。
134
+ - `batch_size_s` 表示采用动态batch,batch中总音频时长,单位为秒s。
135
+ - `merge_vad`:是否将 vad 模型切割的短音频碎片合成,合并后长度为`merge_length_s`,单位为秒s。
136
+ - `ban_emo_unk`:禁用emo_unk标签,禁用后所有的句子都会被赋与情感标签。默认`False`

+ ## 语音识别效果
180
+ 我们在开源基准数据集(包括 AISHELL-1、AISHELL-2、Wenetspeech、Librispeech和Common Voice)上比较了SenseVoice与Whisper的多语言语音识别性能和推理效率。在中文和粤语识别效果上,SenseVoice-Small模型具有明显的效果优势。

187
+
188
+ ## 情感识别效果
189
+ 由于目前缺乏被广泛使用的情感识别测试指标和方法,我们在多个测试集的多种指标进行测试,并与近年来Benchmark上的多个结果进行了全面的对比。所选取的测试集同时包含中文/英文两种语言以及表演、影视剧、自然对话等多种风格的数据,在不进行目标数据微调的前提下,SenseVoice能够在测试数据上达到和超过目前最佳情感识别模型的效果。

+ <img src="fig/ser_table.png" alt="SenseVoice模型SER效果1" width="1500" />
193
+ </p>
194
+
195
+ 同时,我们还在测试集上对多个开源情感识别模型进行对比,结果表明,SenseVoice-Large模型可以在几乎所有数据上都达到了最佳效果,而SenseVoice-Small模型同样可以在多数数据集上取得超越其他开源模型的效果。

200
+
201
+ ## 事件检测效果
202
+
203
+ 尽管SenseVoice只在语音数据上进行训练,它仍然可以作为事件检测模型进行单独使用。我们在环境音分类ESC-50数据集上与目前业内广泛使用的BEATS与PANN模型的效果进行了对比。SenseVoice模型能够在这些任务上取得较好的效果,但受限于训练数据与训练方式,其事件分类效果专业的事件检测模型相比仍然有一定的差距。

210
+
211
+ ## 推理效率
212
+ SenseVoice-Small模型采用非自回归端到端架构,推理延迟极低。在参数量与Whisper-Small模型相当的情况下,比Whisper-Small模型推理速度快7倍,比Whisper-Large模型快17倍。同时SenseVoice-small模型在音频时长增加的情况下,推理耗时也无明显增加。

+ # ZipEnhancer语音降噪模型介绍
53
+
54
+ 用于语音增强任务的最新语音降噪模型。在日常生活中,我们常常会遇到录音环境不佳的情况,比如试图记录一段清晰的语音信息时,周围环境的噪音却不可避免地侵入录音,使得最终录制得到的语音信号中充满了干扰。类似地,在诸如地铁或公交车这类嘈杂的公共场所进行通话时,为了确保通话双方能够听见,人们有时采用提高说话的音量来增强人声信号,来缓解背景噪声的影响。环境噪音对语音通信造成的影响构成了使用语音应用时的一大挑战和障碍。确保语音的高质量传输与高可理解性,常因环境噪声、录音设备的局限性、以及声音的混响和回声效应而变得困难重重,这直接导致了通话清晰度和沟通效率的显著下降。因此,如何在喧嚣的环境里维持高水平的语音质量与可懂度,成为了技术行业和学术界共同努力解决的重要课题。
55
+
56
+ 历经多年的研发探索,语音降噪技术已实现了重要的进展,特别是在应对复杂噪声环境的降噪需求上,采用基于时域、时频域等方法的深度学习神经网络技术,对幅度谱、相位谱以及复数域等声学特征进行高效提取,另外采用双路建模方式提升了语音降噪方法的性能。这些技术能够在极小化语音失真的前提下,高效滤除背景噪音,从而极大地恢复了原始语音的清晰度。这类先进的处理模型也被形象地称为AI语音增强模型。
57
+
58
+ 语音降噪模型的核心功能,在于从充满杂质的音频信号中精准分离并提取出纯净的目标语音,不仅有效提升语音的可听性和可理解性,同时也为语音识别技术的准确度和响应速度带来了显著优化。尤为值得一提的是,我们的语音降噪模型设计精巧,仅需接收单个麦克风录制的原始音频文件作为输入,就能输出经过高效降噪处理的、音质清晰的音频结果。这一过程保持了音频的原始格式不变,仅仅针对性地剔除了噪音与不必要的混响成分,最大化地保存了原始语音的真实性和完整性。
59
+
60
+ 模型的潜在应用场景:
61
+ * 在嘈杂的声学环境中降低噪声影响,甚至是消除噪声。
62
+ * 改善任意来源的音频声学质量,提升语音清晰度。
63
+ * 在各种背景音中提取人声或者背景声。

68
+ ## 模型描述
69
+
70
+ ZipEnhancer是阿里巴巴语音实验室提出的基于时频域(TF-Domain)建模的双路(Dual-Path)可进行时频域特征压缩的语音降噪模型。相比于过去的双路语音增强和语音降噪模型,保留额外的频率维度,构建四维的隐层特征(B, T, F, C),导致了模型的计算量居高不下的问题,我们引入的时频域特征下采样模块,来自定义降低隐层特征维度,减少模型的计算量。
71
+
72
+ 该模型神经网络结构如下图所示。
73
+
74
+ ![model.jpg](description/model.jpg)
75
+
76
+ 该模型包括编码器(Encoder)、双路径压缩变压器块(Dual-Path ZipformerBlocks) 、幅度解码器(Magnitude Decoder)和相位解码器(Phase Decoder)。Encoder最初对幅度(Magnitude)和相位(Phase)进行建模以获得隐藏层特征。随后,Dual-Path ZipformerBlocks使用DownSampleStacks和FT-ZipformerBlocks对频域和时域进行顺序建模,然后由幅度解码器恢复幅度谱,并由相位解码器显式恢复相位谱。我们利用ZipformerBlock将双路径Block构建为FT-ZipformerBlocks。
77
+ 此外,我们提出了具有成对的下采样和上采样结构的DownSampleStacks,我们使用成对的DownSample和UpSample模块实现时间或频率长度的对称缩放,以降低计算成本,并在不同分辨率级别对时域和频域信息进行建模。在时间维度进行下采样的模块称为T_DownSample和T_UpSample,而在频率维度进行下采样的模块称为F_DownSample和F_UpSample。
78
+ 在 DNS Challenge 2020 (DNS2020)和VoiceBank+DEMAND数据集上进行的大量实验证明了我们的ZipEnhancer的���果。
79
+
80
+ ZipEnhancer优于类似规模的模型,在具有2.04M个参数和62.41FLOPS的情况下,**在DNS2020数据集上实现了新的最先进(SOTA)语音质量感知评估(PESQ)得分3.69**,数据集Voicebank+DEMAND上PESQ达到3.63。
81
+
82
+ 模型输入和输出均为16kHz采样率单通道语音时域波形信号,输入信号可由单通道麦克风直接进行录制,输出为噪声抑制后的语音音频信号。模型输入信号通过STFT变换转换成幅度(Magnitude)和相位(Phase)特征作为输入,并采用ZipEnhancer在时频域上进行有效的双路建模和特征压缩,预测最终的增强幅度和相位,降幅度和相位转化后构建增强后的复数域特征,最后通过STFT逆变换得到增强后语音波形信号。
83
+
84
+
85
+ ## 期望模型使用方式以及适用范围
86
+
87
+
88
+ ### 如何使用
89
+
90
+ 在安装ModelScope完成之后即可使用```speech_zipenhancer_ans_multiloss_16k_base```进行推理。模型输入和输出均为16kHz采样率单通道语音时域波形信号,输入信号可由单通道麦克风直接进行录制,输出为噪声抑制后的语音音频信号。为了方便使用在pipeline在模型处理前后增加了wav文件处理逻辑,可以直接读取一个wav文件,并把输出结果保存在指定的wav文件中。
91
+
92
+ #### 环境准备:
93
+
94
+ * 本模型支持Linxu,Windows和MacOS平台。
95
+
96
+ ```
97
+ conda install pytorch torchaudio torchvision -c pytorch
98
+ ```
99
+
100
+ * 本模型的pipeline中使用了三方库SoundFile进行wav文件处理,**在Linux系统上用户需要手动安装SoundFile的底层依赖库libsndfile**,在Windows和MacOS上会自动安装不需要用户操作。详细信息可参考[SoundFile官网](https://github.com/bastibe/python-soundfile#installation)。以Ubuntu系统为例,用户需要执行如下命令:
101
+
102
+ ```shell
103
+ sudo apt-get update
104
+ sudo apt-get install libsndfile1
105
+ ```
106
+
107
+ * 本模型要求modelscope library版本 >=1.20,若不满足可按以下方式进行升级。
108
+
109
+ ```shell
110
+ pip install modelscope==1.22.0
111
+ # 如仍缺少依赖, 可按下述补充安装
112
+ pip install simplejson datasets==2.18.0 addict sortedcontainers
113
+ ```
114
+ * pytorch环境建议显式设置线程数。https://github.com/pytorch/pytorch/issues/90760
115
+
116
+ ```python
117
+ # 设置要使用的线程数,比如8
118
+ import torch
119
+ torch.set_num_threads(8)
120
+ torch.set_num_interop_threads(8)

+ ### 模型局限性以及可能的偏差
430
+
431
+ 该模型仅用DNS Challenge 2020开源数据进行训练,该训练集仅包括英语语种和集内噪声,可能在个别跨域噪声上有性能偏差。
432
+
433
+ ## 训练数据介绍
434
+
435
+ 模型的训练数据来自DNS-Challenge 2020开源数据集,是Microsoft团队为ICASSP相关挑战赛提供的,[官方网址](https://github.com/microsoft/DNS-Challenge)[2]。该模型用来处理16k音频,因此只使用了其中的fullband中的英文数据。
436
+
437
+
438
+ ## 数据评估及结果

+ * WB-PESQ (wide-band Perceptual Evaluation Of Speech Quality) 宽带 (16k) 语音质量感知评估,是一种客观的、全参考的语音质量评估方法,得分范围在-0.5--4.5之间,得分越高表示语音质量越好。
453
+ * NB-PESQ (narrowband Perceptual Evaluation Of Speech Quality) 窄带 (8k) 语音质量感知评估,同上得分越高表示语音质量越好。
454
+ * STOI (Short-Time Objective Intelligibility) 短时客观可懂度,反映人类的听觉感知系统对语音可懂度的客观评价,STOI 值介于0~1 之间,值越大代表语音可懂度越高,越清晰。
455
+ * SI-SDR (Scale Invariant Signal-to-Distortion Ratio) 尺度不变的信干比,是在普通信噪比基础上通过正则化消减信号变化导致的影响,是针对宽带噪声失真的语音增强算法的常规衡量方法。
456
+ * CSIG、CBAK 和 COVL 分别评估了信号失真、背景噪声侵扰性以及整体效果的平均意见得分(Mean Opinion Score,MOS)。指标越高越好。
457
+ * SSNR (Segmental Signal-to-Noise Ratio),分段信噪比,通过将信号分成多个时间段来分别评估各段内的信号纯净度,反映了不同部分中信号与噪声的比例,从而更细致地表明了局部信号质量及噪声影响。指标越高越好。
