AppGen Qwen3-VL frozen SFT — A-variant arm E

This is arm ngcanchorlr2p5e7 from a preregistered four-arm follow-up to the best NGC configuration A. The language model was fully fine-tuned while the complete Qwen3-VL visual tower, merger, and deep-stack mergers remained frozen. Publication verifies every model.visual tensor byte-for-byte against the pinned base and verifies that language-model weights changed.

Only the final checkpoint (checkpoint-113) is published. The exact system prompt is appgensystemprompt.txt; run_manifest.json records exact hashes, the dataset receipt, overlap audit, and weight verification. Intermediate 25-step checkpoints remain local.

Evaluation and limitations

The training/evaluation overlap gate compares EXIF-transposed decoded RGBA pixels plus image dimensions against the seven pinned AW7 test suites. It also compares normalized instruction hashes. The exact pinned receipt must report zero train/eval pixel and instruction overlaps for every data variant and suite before publication. Static grounding benchmarks are not a substitute for interactive AndroidWorld task success, and no score is claimed in this card.

This model is for Android visual-agent research, not safety-critical autonomous deployment.
