# Qwen2.5-Coder-3B-Instruct-FP8-dynamic
|
||||
|
||||
## Model Overview
|
||||
- **Model Architecture:** Qwen2ForCausalLM
|
||||
- **Input:** Text
|
||||
- **Output:** Text
|
||||
- **Model Optimizations:**
|
||||
- **Activation quantization:** FP8
|
||||
- **Weight quantization:** FP8
|
||||
- **Release Date:** 09/06/2025
|
||||
- **Version:** 1.0
|
||||
- **Model Developers:** duydq12 (enhance by RedHatAI)
|
||||
|
||||
### Model Optimizations
|
||||
|
||||
This model was obtained by quantizing activations and weights of [Qwen2.5-Coder-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-3B-Instruct) to FP8 data type.
|
||||
This optimization reduces the number of bits used to represent weights and activations from 16 to 8, reducing GPU memory requirements (by approximately 50%) and increasing matrix-multiply compute throughput (by approximately 2x).
|
||||
Weight quantization also reduces disk size requirements by approximately 50%.
|
||||
|
||||
Only weights and activations of the linear operators within transformers blocks are quantized.
|
||||
Weights are quantized with a symmetric static per-channel scheme, whereas activations are quantized with a symmetric dynamic per-token scheme.
|
||||
The [llm-compressor](https://github.com/vllm-project/llm-compressor) library is used for quantization.
|
||||
|
||||
|
||||
## Deployment
|
||||
|
||||
This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend, as shown in the example below.
|
||||
|
||||
```python
|
||||
from vllm import LLM, SamplingParams
|
||||
from transformers import AutoTokenizer
|
||||
|
||||
model_id = "duydq12/Qwen2.5-Coder-3B-Instruct-FP8-dynamic"
|
||||
number_gpus = 1
|
||||
sampling_params = SamplingParams(temperature=0.6, top_p=0.95, top_k=20, min_p=0, max_tokens=256)
|
||||
|
||||
messages = [
|
||||
{"role": "user", "content": prompt}
|
||||
]
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||
|
||||
messages = [{"role": "user", "content": "Give me a short introduction to large language model."}]
|
||||
|
||||
prompts = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
|
||||
|
||||
llm = LLM(model=model_id, tensor_parallel_size=number_gpus)
|
||||
|
||||
outputs = llm.generate(prompts, sampling_params)
|
||||
|
||||
generated_text = outputs[0].outputs[0].text
|
||||
print(generated_text)
|
||||
```
|
||||
|
||||
vLLM aslo supports OpenAI-compatible serving. See the [documentation](https://docs.vllm.ai/en/latest/) for more details.

|

<summary>Creation details</summary>
|
||||
This model was created with [llm-compressor](https://github.com/vllm-project/llm-compressor) by running the code snippet below.
|
||||
|
||||
|
||||
```python
|
||||
from llmcompressor.modifiers.quantization import QuantizationModifier
|
||||
from llmcompressor.transformers import oneshot
|
||||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||||
|
||||
# Load model
|
||||
model_stub = "Qwen/Qwen2.5-Coder-3B-Instruct"
|
||||
model_name = model_stub.split("/")[-1]
|
||||
|
||||
model = AutoModelForCausalLM.from_pretrained(model_stub, torch_dtype="auto", device_map="auto")
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_stub, torch_dtype="auto", device_map="auto")
|
||||
|
||||
# Configure the quantization algorithm and scheme
|
||||
recipe = QuantizationModifier(
|
||||
ignore=["lm_head"],
|
||||
targets="Linear",
|
||||
scheme="FP8_dynamic",
|
||||
)
|
||||
|
||||
# Apply quantization
|
||||
oneshot(
|
||||
model=model,
|
||||
recipe=recipe,
|
||||
)
|
||||
|
||||
# Save to disk in compressed-tensors format
|
||||
save_path = model_name + "-FP8-dynamic"
|
||||
model.save_pretrained(save_path)
|
||||
tokenizer.save_pretrained(save_path)
|
||||
print(f"Model and tokenizer saved to: {save_path}")
|
||||
```
