# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->

This is a int4_awq quantized checkpoint of bigcode/starcoder2-15b. It takes about 10GB of VRAM.

## Running this Model
vLLM does not natively support autoawq currently (or any a4w8 as of writing this), so one can just serve directly from the autoawq backend.

Note, if you want to start this in a container, then:
`docker run --gpus all -it --name=starcoder2-15b-int4-awq -p 8000:8000 -v ~/.cache:/root/.cache nvcr.io/nvidia/pytorch:24.12-py3 bash`

`pip install fastapi[all] torch transformers autoawq`

Then in python3:
```
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
import torch
from awq import AutoAWQForCausalLM
from transformers import AutoTokenizer
import uvicorn

# Define the FastAPI app
app = FastAPI()

# Define the request body model
class TextRequest(BaseModel):
    text: str

# Load the quantized model and tokenizer
model_path = '/root/.cache/huggingface/hub/models--shavera--starcoder2-15b-w4-autoawq-gemm/snapshots/13fab46ef237de327397549f427106890e0dec67'
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

model = AutoAWQForCausalLM.from_quantized(model_path, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)

# Ensure the model is in evaluation mode
model.eval()

# Create the inference function
def generate_text(prompt: str) -> str:
    inputs = tokenizer(prompt, return_tensors="pt").to(device)
    outputs = model.generate(**inputs)
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Define the API endpoint for text generation
@app.post("/generate")
async def generate(request: TextRequest):
    try:
        generated_text = generate_text(request.text)
        return {"generated_text": generated_text}
    except Exception as e:
        raise HTTPException(status_code=500, detail=str(e))

# Run the server (port 8000)
if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)
```
