mistral-small-3.1-24b-harmoni-sft-dpo

Version: v1.0.0

Model Description

This model is a fine-tuned version of mistralai/Mistral-Small-3.1-24B-Instruct-2503 for manufacturing domain applications.

Training Method: Sequential SFT (Supervised Fine-Tuning) followed by DPO (Direct Preference Optimization)

Training Pipeline:

1. SFT Phase: LoRA fine-tuning on domain-specific instruction data
2. DPO Phase: Preference optimization for alignment
3. Merge: Weighted merge of SFT and DPO adapters with base model

Training Configuration

• PEFT Strategy: aggressive
• SFT Configuration: aggressive
• Dataset: UltraChat Dataset
• Hardware: Multi-GPU (FSDP/DeepSpeed)
• Context Length: 128K tokens
• Training Framework: HuggingFace Transformers + PEFT

Usage

Using Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "ssoni-harmoni/mistral-small-3.1-24b-harmoni-sft-dpo"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    device_map="auto",
    torch_dtype="auto"
)

messages = [
    {"role": "system", "content": "You are a helpful manufacturing assistant."},
    {"role": "user", "content": "What are the key steps in CNC machining?"}
]

inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)
outputs = model.generate(inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Using vLLM (Recommended for Quantized Models)

from vllm import LLM, SamplingParams

llm = LLM(
    model="ssoni-harmoni/mistral-small-3.1-24b-harmoni-sft-dpo",
    quantization="compressed-tensors",
    tensor_parallel_size=1
)

sampling_params = SamplingParams(temperature=0.7, top_p=0.9, max_tokens=512)
outputs = llm.generate("What are the key steps in CNC machining?", sampling_params)
print(outputs[0].outputs[0].text)
