The benchmarks the big labs don't want you to see

Explain Like I'm Normal

A community-driven investigation on r/LocalLLaMA highlights non-standard benchmarks that expose how frontier models often fail at basic logic despite high MMLU scores. These 'needle-in-a-haystack' and logic-twist tests suggest big labs are over-optimizing for common evaluations. Founders are using these to find models that actually work in production rather than just on paper.
