ColGrep-Agent-2B - MLX 8BIT

Native Apple Silicon MLX conversion of LightOn's ColGrep-Agent-2B, a specialized repository code-localization agent built on MiniCPM5-2B.

Upstream checkpoint: lightonai/colgrep-agent-2B at f798a61129c6decb5166864e0a3c98373e62c764
Conversion: MLX-LM 0.32.0, 8-bit affine, group size 64
Compatibility: source chat_template.jinja preserved; top-level rope_theta=5000000 added so MLX-LM's Llama RoPE implementation matches the source configuration.
Original model authors: LightOn AI; original model license: Apache-2.0.

Usage

pip install 'mlx-lm==0.32.0' 'transformers>=5.6.2,<6'
mlx_lm.generate --model . --prompt 'Hello' --max-tokens 128

This is not a general coding assistant. It was trained for iterative code search with colgrep, terminal, and finish. Use the upstream chat template, system prompt, tool schemas, and thinking disabled. The official colgrep --agent CLI currently runs GGUF through llama.cpp; this MLX checkpoint is not a drop-in replacement for that CLI. An MLX-backed harness is separate integration work.

This checkpoint is not claimed to match upstream BF16 on benchmarks until an apples-to-apples evaluation of full search trajectories is reported. The smoke test validates basic load, format, and first tool-call structure only.
