Instructions to use drawais/Phi-4-reasoning-NVFP4 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use drawais/Phi-4-reasoning-NVFP4 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="drawais/Phi-4-reasoning-NVFP4")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("drawais/Phi-4-reasoning-NVFP4")
model = AutoModelForCausalLM.from_pretrained("drawais/Phi-4-reasoning-NVFP4")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Phi-4-reasoning-NVFP4

INT4 weight-only quantization of microsoft/Phi-4-reasoning.

Microsoft Phi-4-reasoning in NVFP4 W4A4. Native vLLM compressed-tensors. About 8 GB on disk.

Property	Value
Base model	microsoft/Phi-4-reasoning
Quantization	INT4 weight-only
Approx. on-disk size	~9.7 GB
License	MIT License
Languages	English

Load (vLLM)

vllm serve drawais/Phi-4-reasoning-NVFP4 \
  --max-model-len 32768 \
  --gpu-memory-utilization 0.94

from vllm import LLM, SamplingParams
llm = LLM(model="drawais/Phi-4-reasoning-NVFP4", max_model_len=32768)
print(llm.generate(["Hello!"], SamplingParams(max_tokens=128))[0].outputs[0].text)
