Piccolo-27B is a decision model for tool review and context selection. This repository contains the complete Safetensors checkpoint.

## Download

```bash
hf download agentscope-ai/Piccolo-27B --local-dir Piccolo-27B
```

## Reference inference

Use the included reference implementation for bidirectional attention and candidate scoring.

```bash
python -m pip install -r Piccolo-27B/requirements.txt
python Piccolo-27B/piccolo_inference.py --model Piccolo-27B --request request.json --device cuda:0
```

Use the [request example](https://github.com/agentscope-ai/Piccolo/tree/main/inference) to prepare `request.json`.

## QwenPaw

Use Piccolo locally for tool review and context selection with the [QwenPaw setup guide](https://github.com/agentscope-ai/Piccolo/blob/main/docs/QWENPAW.md).
