Verification verdict

Of 9 models in the ensemble, 9 responded successfully and 0 failed.

Per-model responses

The full text of each model's response is available in the source ledger. The summary below records each model's success or failure and the first 280 characters of its response.

| Model | Status | Response chars | | --- | :---: | ---: | | gpt-4.1-mini | ✓ | 370 | | gpt-4.1-nano | ✓ | 2939 | | gpt-oss-120b | ✓ | 578 | | grok-3-mini | ✓ | 11865 | | grok-4-fast | ✓ | 5333 | | kimi-k2-groq | ✓ | 750 | | llama-3.3-70b | ✓ | 1562 | | llama-4-scout | ✓ | 2996 | | qwen3-32b | ✓ | 7182 |

Pairwise agreement

The pairwise Jaccard agreement between successful responses for this cycle:

_Per-cycle pairwise agreement matrix is computed offline; will be populated in canonical page v2._

Divergence score

This cycle's divergence score is **TBD** on a 0 to 1 scale, where 0 means all responses are token-identical and 1 means no two responses share any tokens. The dataset-wide median divergence is 0.5 for context.
