# kernelpool/LongCat-2.0-3bit

3-bit quantization of [meituan-longcat/LongCat-2.0](https://huggingface.co/meituan-longcat/LongCat-2.0),
converted with [mlx-lm](https://github.com/ml-explore/mlx-lm).

> **Revision note**: originally converted from the FP8 release

## Use with mlx

This model requires LongCat-2.0 support from [mlx-lm PR #1464](https://github.com/ml-explore/mlx-lm/pull/1464),
which has not yet been merged. Until it is included in an mlx-lm release, install
mlx-lm from the PR branch:

```bash
pip install git+https://github.com/ml-explore/mlx-lm.git@refs/pull/1464/head
```

```python
from mlx_lm import load, generate

model, tokenizer = load("kernelpool/LongCat-2.0-3bit")

prompt = "hello"

if tokenizer.chat_template is not None:
    messages = [{"role": "user", "content": prompt}]
    prompt = tokenizer.apply_chat_template(
        messages, add_generation_prompt=True, return_dict=False,
    )

response = generate(model, tokenizer, prompt=prompt, verbose=True)
```
