FrontAgent Planner 14B LoRA MLX

This repository contains a FrontAgent Planner-only LoRA adapter trained with MLX-LM on Apple Silicon. It generates structured frontend engineering execution plans for FrontAgent. It does not directly generate business code, run tools, or make repository changes. Generated plans still require FrontAgent schema validation and runtime safety checks.

Limitations

• This adapter is MLX-LM format, not a PEFT/Transformers adapter.
• It is optimized for FrontAgent planning JSON, not general coding.
• Generated plans must be schema-checked before execution.
• Loss metrics are from the deterministic v2 dataset split; run FrontAgent generated-plan quality evaluation before production rollout.
