EpochAI reviews 8 agent benchmarks: only 1 verified, 3 flawed — and coding agents may break the reward trilemma

EpochAI published 4 new benchmark reviews: only 1 is Verified, 3 are Flawed, and 4 more lacked sufficient information for a verdict; reviewer capacity is its main bottleneck.
Quoting this, TianbaoX frames an "impossible triangle" for real-world agents: reliable verifiable rewards, broad task coverage, and low human effort. He argues coding agents could change the economics — writing verifiers, generating counterexamples, and turning failures into regression tests. The hard part is validating those verifiers against what users actually want; merely generating more grading code won't solve it, but scaling that validation could make the "impossible" part disappear.
