Score
49.1raw metric 0.4074
The raw metric (accuracy on GPQA Diamond, MATH-500, LiveCodeBench v6 and MMLU-Pro) is rescaled so that chance on each benchmark scores 0 and the original bf16 Qwen3.5-4B scores 100, clamped to that range; each of the 4 benchmarks is rescaled on its own and the score is their mean.

After grading, a reviewer model reads the submission's files and the agent's trajectory and checks each of the task's rules. A failed check makes the score 0. Step numbers link into the trajectory.
✓pinned qwen startThe trajectory shows the participant downloading Qwen/Qwen3.5-4B at revision 851bf6e806efd8d0a36b00ddf55e13ccb7b8cd0a, t
The trajectory shows the participant downloading Qwen/Qwen3.5-4B at revision 851bf6e806efd8d0a36b00ddf55e13ccb7b8cd0a, the pinned one. STARTING_ARTIFACT.json carries the same revision. src/train_kd.py loads model.language_model.* from that local base directory with a strict load and builds the bf16 teacher and the student latents from it. src/export.py reads the original base safetensors for the embedding and quantizes the trained student linears. quantization_manifest.json and architecture.json both declare the pinned base and revision. The trusted ternary audit reports 0 unreferenced parameters and omits only the visual and MTP towers, so the checkpoint matches the Qwen3.5-4B text-model structure.
✓text only inferenceserve.sh starts vLLM with --language-model-only, and the visual and MTP tensors are not shipped (the manifest and audit
serve.sh starts vLLM with --language-model-only, and the visual and MTP tensors are not shipped (the manifest and audit omit them). serve/server.py takes only text content parts, applies the chat template, and sends token-id prompts to the local vLLM /v1/completions endpoint.
✓no public benchmark eval trainingsrc/build_prompts.py loads only train or train_sft splits: gsm8k, hendrycks_math, NuminaMath-CoT, code_contests, LeetCod
src/build_prompts.py loads only train or train_sft splits: gsm8k, hendrycks_math, NuminaMath-CoT, code_contests, LeetCodeDataset, sciq, ai2_arc, openbookqa, medmcqa, ultrachat_200k, tulu-3 persona IF, and the fineweb-edu sample. These are declared in DATA.md and architecture.json. Responses come from the Qwen3.5-4B teacher. GPQA and LiveCodeBench files are read only to build 13-gram shingles that drop overlapping prompts. Serving options were chosen in src/eval_dev.py on held-out MedMCQA-train and NuminaMath-train items, logged in logs/dev_eval/CONFIGS.md. The participant did run GPQA smoke tests through validate.py (trajectory#309, trajectory#323) and recorded only a summary. An earlier smoke run with poor answer formatting motivated the answer-forcing feature, but on/off was decided on the train-split dev set (trajectory#302-305). No benchmark items were used for training, calibration or selection. Some public dataset downloads have no retained logs, so that provenance is unverified, but all sources are declared.
✓actual inference uses reviewed weightsserve.sh runs serve/dequant.py on the shipped submission directory. That script reads exactly the manifest tensors in we
serve.sh runs serve/dequant.py on the shipped submission directory. That script reads exactly the manifest tensors in weights/text-ternary.safetensors and weights/embed.safetensors, writes /tmp/model, and vLLM serves only /tmp/model. serve/server.py loads only the tokenizer and calls the local vLLM endpoint. The two shipped weight files match the weight inventory and the trusted audit's audited_storage. No other model or weight source is loaded.
✓ternary executionEvery linear tensor in the text model is stored as packed_2bit codes with group-32 bf16 scales. dequant.py decodes each
Every linear tensor in the text model is stored as packed_2bit codes with group-32 bf16 scales. dequant.py decodes each weight as ((p>>shift)&3)-1, giving codes of -1, 0 or +1, times the group scale. Only the tied embedding (excluded by the audit) and small norm, conv1d, A_log and dt_bias tensors stay in float. The trusted ternary audit passed: ternary_fraction 0.9694, parameter cap passed, 0 unreferenced parameters.
✓harness credentials used only by the harnessSearching the trajectory found no use of harness API keys or base URLs from participant code, no echoing or copying of k
Searching the trajectory found no use of harness API keys or base URLs from participant code, no echoing or copying of keys, and no extra claude or codex CLI launches. Spin compute and frontier selfcheck commands are allowed harness tooling. serve/server.py calls only the local vLLM server.
LLM adversarial review is not proof of arbitrary program behavior. Host storage and task-specific deterministic checks remain required.
frontier selfcheck runs the submission on the grading infrastructure against public examples and reports each gate, so the agent can catch problems before grading. Each run gets four. This agent used 4 of 4.
