AutoWeight

Repair a fine-tuning regression in a local Hugging Face checkpoint while preserving behavior you want to keep. AutoWeight tests proposed weight edits on development examples and exports a standard Transformers checkpoint when one selected edit passes a separate confirmation set.

Try the offline demo

Use Python 3.11 or newer on macOS or Linux.

uv tool install 'auto-weight[hf,mcp]'
auto-weight demo

The demo generates a tiny model locally, runs two scripted edits, and prints the scores and the exported model path. For a pip installation, use python -m pip install 'auto-weight[hf,mcp]' in an active virtual environment.

Repair your own model

Bring a local safetensors checkpoint and labeled development and confirmation sets. For Codex or Claude Code, run auto-weight setup-runtime --input-root /path/to/repair-inputs using your existing input directory, then load the AutoWeight plugin from the repository. For terminal use, run auto-weight repair with a local Ollama proposer or use the manual proposal commands.
