# Samantha Qwen2 1.5B

This model was trained on 2xL40S using FSDP and QLoRa. FP16 Merge is available [here](https://huggingface.co/macadeliccc/Samantha-Qwen2-1.5B)

## Prompt Template

```
<|im_start|>system
You are a helpful AI assistant<|im_end|>
<|im_start|>user
What is the capital of France?<|im_end|>
<|im_start|>assistant
```

## Launch Using VLLM

```bash
python -m vllm.entrypoints.openai.api_server \
    --model macadeliccc/Samantha-Qwen2-1.5B \
    --chat-template ./examples/template_chatml.jinja \
```

```python
from openai import OpenAI
# Set OpenAI's API key and API base to use vLLM's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://localhost:8000/v1"

client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)

chat_response = client.chat.completions.create(
    model="macadeliccc/Samantha-Qwen-2-1.5B",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Tell me a joke."},
    ]
)
print("Chat response:", chat_response)
```
