Case 09 · Industry-wide

AI benchmarks are saturated. Real measurement moved elsewhere.

MMLU 99%. SWE-bench dropped. RAID top-10 is the same story.

The failure · on the record

MMLU is saturated — frontier LLMs cluster at 99% with 2–3 point gaps that are statistical noise. OpenAI stopped reporting SWE-bench Verified in 2025 because “the score stopped meaning anything.” LiveCodeBench uses publication-dated problems so models cannot memorize what they haven’t seen. RAID’s top-10 is where SWE-bench was in 2024. Public benchmarks stop being tests once vendors fine-tune on the labels.

What we do differently

We publish signed benchmarks AND accept adversarial submissions. Bring your own test set of any size. Every score is Ed25519-signed and returned with a certificate you can cite.

The buyer’s test set can not be memorized because the vendor has not seen it.
