# Bielik-11B-v2.0-Instruct-FP8

This model was obtained by quantizing the weights and activations of [Bielik-11B-v.2.0-Instruct](https://huggingface.co/speakleash/Bielik-11B-v2.0-Instruct) to FP8 data type, ready for inference with vLLM >= 0.5.0 or SGLang. 
AutoFP8 is used for quantization. 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. Symmetric per-tensor quantization is applied, in which a single linear scaling maps the FP8 representations of the quantized weights and activations. 

FP8 compuation is supported on Nvidia GPUs with compute capability > 8.9 (Ada Lovelace, Hopper).

**DISCLAIMER: Be aware that quantised models show reduced response quality and possible hallucinations!**

## Use with vLLM

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 = "speakleash/Bielik-11B-v2.0-Instruct-FP8"

sampling_params = SamplingParams(temperature=0.2, top_p=0.95, max_tokens=4096)

tokenizer = AutoTokenizer.from_pretrained(model_id)

messages = [
    {"role": "system", "content": "Jesteś pomocnym asystentem Bielik."},
    {"role": "user", "content": "Kim był Mikołaj Kopernik i z czego zasłynął?"},
]

prompts = tokenizer.apply_chat_template(messages, tokenize=False)

llm = LLM(model=model_id, max_model_len=4096)

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.


## Use with SGLang Runtime
Launch a server of SGLang Runtime:

```
python -m sglang.launch_server --model-path speakleash/Bielik-11B-v2.0-Instruct-FP8 --port 30000
```

Then you can send http request or use OpenAI Compatible API. 

```python
import openai
client = openai.Client(
    base_url="http://127.0.0.1:30000/v1", api_key="EMPTY")

response = client.chat.completions.create(
    model="default",
    messages=[
        {"role": "system", "content": "Jesteś pomocnym asystentem Bielik."},
        {"role": "user", "content": "Kim był Mikołaj Kopernik i z czego zasłynął?"},
    ],
    temperature=0,
    max_tokens=4096,
)
print(response)

```
