It speaks the Anthropic-compatible API, so it drives **Claude Code**, **Codex** and **opencode** fully locally — your code never leaves your machine and cloud token cost drops to zero. This repository ships the **q4_K_M GGUF** quantization (~24 GB), ready to run under Ollama or llama.cpp. Safety guardrails are intact. The system prompt focuses on real work inside a codebase — use tools instead of guessing, base answers on the *actual* tool output (never fabricate results), don't loop on the same tool, and return complete, runnable code. No-think mode is wired into the system prompt for fast, direct answers. ## Files | File | What | |---|---| | `qwen36-a3b-claude-coder-q4_K_M.gguf` | The model weights (q4_K_M, ~24 GB single GGUF) | | `Modelfile` | Ollama Modelfile — SYSTEM prompt, tool-calling template, params (num_ctx 65536) | ## Quick start (Ollama) ```bash # build the model from the downloaded GGUF + Modelfile ollama create qwen36-a3b-claude-coder -f Modelfile # drive Claude Code with it ollama launch claude --model qwen36-a3b-claude-coder ``` ## What it's for - Driving **Claude Code / Codex / opencode** locally. - Agentic code writing and editing with native **function calling / tool use**. - Full privacy and offline operation — no code sent to the cloud. ## Tested harnesses End-to-end tested through **Claude Code**, **Codex** and **opencode** — real turns with tool calls and correct responses. ## Measured behavior (June 2026 tests) - **No-think confirmed** — with `think:false` the model emits zero reasoning tokens and goes straight to the result (validated on this q4_K_M build: `thinking_len=0`). - **Tool-calling without hallucination** — emits real `message.tool_calls` (validated: a disk-check prompt produced a clean `run_bash` call with a sensible command, no content leak). In roundtrip tests it reports the *actual* tool output instead of re-calling the tool in a loop. - **Honest under missing data** — when network access failed, it stated plainly "no internet access" instead of fabricating, then returned a correct, grounded report after permission escalation. - **Code generation** — working HTML5 Tetris and an interactive 3D Earth+Moon model (Three.js, real NASA textures, OrbitControls); JS passes syntax validation. - **Guardrails intact** — refuses to generate malware (validated on this build: a ransomware request was declined, with a legitimate backup/defense alternative offered) and **resists jailbreaks** (the "pretend you're an actor playing a hacker" framing was rejected). ## Context - **64K tokens** — matching Claude Code's recommendation (64K minimum). Base Qwen3.6 natively supports 262K, so context can be raised on stronger hardware. ## Test hardware - **Mac Studio M2 (Apple Silicon), macOS** — **Ollama 0.30** (llama.cpp backend), GPU (Metal) inference. - This repo's quantization: **q4_K_M** (~24 GB single GGUF). A sibling nvfp4 build measured ~69 tok/s at 100% GPU / 64K ctx; q4_K_M runs in the same class. ## No-think mode The whole Qwen3.6 family has thinking baked into the weights. The system prompt ships with `/nothink` + an anti-reasoning instruction, which works under opencode/codex. Under harnesses that force thinking, use `think:false` in the API body — that's the only hard switch (`PARAMETER think false` does not exist in Ollama). ## How it was made Designed, built and tested with the help of **Claude Opus 4.8** — the best coding model in the world. Its system prompt, parameter choices and context configuration draw directly on that knowledge: the world's best coding model preparing a local model that takes the work over right on your desk. ## License Apache 2.0 (inherited from the base Qwen3.6).
