Model Overview

  • —Model Architecture: granite-3.1-8b-instruct
  • —Input: Text
  • —Output: Text
  • —Model Optimizations:
  • —Weight quantization: FP8
  • —Activation quantization: FP8
  • —Release Date: 1/8/2025
  • —Version: 1.0
  • —Validated on: RHOAI 2.20, RHAIIS 3.0, RHELAI 1.5
  • —Model Developers: Neural Magic

Quantized version of ibm-granite/granite-3.1-8b-instruct. It achieves an average score of 70.57 on the OpenLLM benchmark (version 1), whereas the unquantized model achieves 70.30.

Model Optimizations

This model was obtained by quantizing the weights and activations of ibm-granite/granite-3.1-8b-instruct to FP8 data type, ready for inference with vLLM >= 0.5.2. This optimization reduces the number of bits per parameter from 16 to 8, reducing the disk size and GPU memory requirements by approximately 50%. Only the weights and activations of the linear operators within transformers blocks are quantized.

Deployment

Use with vLLM

This model can be deployed efficiently using the vLLM backend, as shown in the example below.

python
from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

max_model_len, tp_size = 4096, 1
model_name = "neuralmagic/granite-3.1-8b-instruct-FP8-dynamic"
tokenizer = AutoTokenizer.from_pretrained(model_name)
llm = LLM(model=model_name, tensor_parallel_size=tp_size, max_model_len=max_model_len, trust_remote_code=True)
sampling_params = SamplingParams(temperature=0.3, max_tokens=256, stop_token_ids=[tokenizer.eos_token_id])

messages_list = [
    [{"role": "user", "content": "Who are you? Please respond in pirate speak!"}],
]

prompt_token_ids = [tokenizer.apply_chat_template(messages, add_generation_prompt=True) for messages in messages_list]

outputs = llm.generate(prompt_token_ids=prompt_token_ids, sampling_params=sampling_params)

generated_text = [output.outputs[0].text for output in outputs]
print(generated_text)

vLLM also supports OpenAI-compatible serving. See the documentation for more details.
