# KAT-Coder-V2.5-Dev-oQ2

This model was quantized using [oQ](https://github.com/jundot/omlx) (oMLX v0.5.4) mixed-precision quantization.

- Base model: [Kwaipilot/KAT-Coder-V2.5-Dev](https://huggingface.co/Kwaipilot/KAT-Coder-V2.5-Dev)
- Chat template: [Qwen Fixed Chat Template](https://huggingface.co/froggeric/Qwen-Fixed-Chat-Templates) (v21) — fixes KV cache optimization, thinking mode control, tool calling, and agent loop issues. Original backed up as `chat_template.jinja.bak`.

## Quantization details

- **Model type**: qwen3_5_moe
- **Bits**: 2
- **Group size**: 64
- **Format**: MLX safetensors
- **Calibration**: oQ2 (standard sensitivity-based)

## Environment

- **Hardware**: M5 MacBook Air 32GB
- **Inference Framework**: oMLX v0.5.4
- **Max Concurrent Requests**: 4
- **Settings**:
  - Thinking: Disabled
  - TurboQuant KV Cache: Enabled (4-bit)
