MiniCPM5 1B + Automaticity V9 LoRA

Rank-16 response-only LoRA trained for one epoch on the private Automaticity V9 friendly direct-tool corpus. This is a strong validation candidate, not a production-promoted autonomous router.

The model routes one current thought to at most one available tool, or makes no tool call. Training used MiniCPM5's native XML tool calls with thinking disabled and loss only on the assistant turn.

Frozen validation result

Evaluation used 1,050 private validation rows with normal five-tool retrieval, no gold injection, 100% action-gold retrieval recall, thinking disabled, and no decoding constraint. The validation dataset SHA-256 is 85094c96ca7fa2f96cbb0f7f85bd08510d56b9d4639646156d8806680bca9715.

The untuned base on the identical CUDA validation condition scored 16.29% end-to-end exact, 28.38% routing, 52.24% action exact, and 1.08% no-tool recall.

Limitations

This adapter is not yet promoted for autonomous execution. The frozen validation set still contains 17 wrong-tool rows and 79 wrong-argument rows; action exact is 69.55%. Nested XML arguments are a recurring failure mode. Use strict listed-name and schema validation or constrained decoding and reject invalid calls at runtime. Constraints cannot repair semantically wrong listed tools or schema-valid wrong arguments.
