AI benchmarks may understate AI by 82%: routing across 44 LLMs cuts errors 46%

Martian's peer-reviewed AI Frontier research argues standard benchmarks systematically understate AI: they test one model, one run, ignoring model specialization and consistency. By routing requests across 44 LLMs to build a "Capability Frontier" at every cost level, the team reports 46% fewer errors than the single best LLM across 16 major benchmarks (TerminalBench, LiveCodeBench, etc.), with error reduction or cost savings at matched SOTA cost/quality. They estimate standard benchmarks miss up to 82% of actual AI capability. Interactive site and paper available.
