# nonnon-small

NONNON-small is a closed-weight deep reasoning model served through an OpenAI-compatible API. It is designed for LegalBench-style tasks and is available for evaluation through `https://small.nonnon.ai/v1/chat/completions`.

## Access

Email labs@nonnon.ai to request an evaluation token. Tokens are free for legitimate evaluation purposes and rate-limited for fair use.

## How To Use

```python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_NONNON_TOKEN",
    base_url="https://small.nonnon.ai/v1",
)

response = client.chat.completions.create(
    model="nonnon1-small-router",
    messages=[{"role": "user", "content": "Your LegalBench prompt"}],
    temperature=0,
)

print(response.choices[0].message.content)
```
