DEEP BENCHMARK
What the run established.
Counts stay visible for auditability. A score appears only when the Most Annoying 50-trap view satisfies the independent checks.
DeepSeek describes this model family in its official updates and transparency material. Capabilities stated there are provider claims, separate from our benchmark.

METHOD & LIMITS
What this page can say.
Every public leaderboard clean percentage uses the last four complete checks, covering roughly two weeks, once enough certified history exists; until then it uses the latest Most Annoying 50-trap view. The 100-task run receipt is the wider audit bundle, not the benchmark denominator. Benchmark rank #1 means fewest verified mistakes among complete runs; the list can still be sorted by most mistakes for readability. OpenRouter feed rank is separate discovery metadata and is kept out of the benchmark rank column. Two-week average reporting will use the last four complete 100-task cycles when enough cycles exist. Individual verified mistakes, called catches internally, require primary and shadow checks to reproduce the exact mismatch from the recorded reply against the frozen expected output. Retrieval is not signature verification; auditors should recompute receipt roots and verify signatures against the published issuer key. Routing errors, timeouts, incomplete answers, and missing evidence stay outside the ranked score. Do not judge any model solely from this benchmark. Ranked complete runs must use the same 50 traps, scoring rules, model settings, and retry policy.
Dual-check reproduction
For each listed Most Annoying mistake, primary and shadow verification must both reproduce the exact mismatch from the recorded reply against the frozen expected output. Otherwise the item remains unresolved.
Certified denominator
The rankable score is the 50-trap Most Annoying view. The run receipt may say 100 tasks because it covers the wider audit bundle; that object is evidence, not a separate leaderboard denominator.
Signature and feed rank
Independent verification means recomputing the receipt root and checking the signature against the published issuer public key. OpenRouter rank stays discovery metadata and does not affect benchmark rank.

Claim ceiling: OpenRouter rank and metadata describe the captured discovery feed. Provider claims are separate from this benchmark. Scores describe the most recent public test pack and should not be used alone to judge the model generally.
