# KAT-Coder-V2.5-Dev-oQ4e-mtp
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)
- MTP head: [Qwen/Qwen3.6-35B-A3B](https://huggingface.co/Qwen/Qwen3.6-35B-A3B) (original MTP head grafted)
- 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**: 4
- **Group size**: 64
- **Format**: MLX safetensors
- **MTP**: Grafted from Qwen3.6-35B-A3B (bf16 original)
- **Calibration**: oQ4e (enhanced, imatrix-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)
- Lightning MTP: Enabled (key speed improvement)
