ThinkingCap-Test submission: Martin Senkyr

Qwen3-0.6B with one extra decoder layer inserted after layer 13. Only 64 of its MLP channels are trained (about 198k parameters), on shorter reasoning traces the student wrote with brevity hints from Qwen3-8B. It is a plain 29-layer Qwen3 checkpoint, so it loads in stock Transformers and vLLM with no custom code.

Checkpoint Tokens saved Accuracy change
root: extra-mlp-64, step 170 (half an epoch) 28.7% [27.5, 30.0] −1.71 pp [−2.40, −1.02]

Scored with the unmodified evaluate.py and compare.py of ThinkingCap-Test at bd52d8d, full 8 samples per question. The method and all results are in IDEA.md and data.md.

Contents

  • model.safetensors, config.json, tokenizer files: the main checkpoint (evaluate.py --model mrtineu/<this repo>)
  • results.json: its evaluate.py output
  • base/results.json: the Qwen3-0.6B baseline it is compared against
  • base-local/results.json: the same baseline loaded by local path, the way the checkpoints were; every comparison moves by at most 0.1% tokens and 0.02 pp against it
  • other-checkpoints/: later steps of the same run, the same layer placed after layer 20, and the LoRA run
  • martin-senkyr.bundle: the code as a git bundle (git clone martin-senkyr.bundle); code/ is the same code, readable here
