Instructions to use RedHatAI/Meta-Llama-3.1-8B-Instruct-FP8 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use RedHatAI/Meta-Llama-3.1-8B-Instruct-FP8 with Transformers:

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

pipe = pipeline("text-generation", model="RedHatAI/Meta-Llama-3.1-8B-Instruct-FP8")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("RedHatAI/Meta-Llama-3.1-8B-Instruct-FP8")
model = AutoModelForCausalLM.from_pretrained("RedHatAI/Meta-Llama-3.1-8B-Instruct-FP8")
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]:]))

Does this model only work on CUDA devices with compute capability >= 9.0 or 8.9/ROCm MI300+?

When trying to deploy this on SageMaker using the DJLServing 0.29.0 LMI image with vLLM I get this error:

RuntimeError: torch._scaled_mm is only supported on CUDA devices with compute capability >= 9.0 or 8.9, or

Hi @jcfasi , vLLM has support for fp8 on Ampere (compute capability >= 8.0) as well! See https://docs.vllm.ai/en/latest/quantization/fp8.html

If you are running into issues, please post them at https://github.com/vllm-project/vllm/
