LLM Model Benchmarking from Real Production Traffic

C5/10May 30, 2026
WhatA platform that generates model quality and cost rankings based on anonymized real-world production usage data rather than synthetic benchmarks.
SignalCommenters note that OpenRouter's rankings are one of the few interesting signals about model popularity but are deeply flawed — you cannot distinguish whale users from broad adoption, and most serious users of top models bypass routers entirely.
Why NowThe number of frontier and open-weight models has exploded past the point where teams can manually evaluate them, and synthetic benchmarks are increasingly gamed, creating demand for real-world performance signals.
MarketAI engineering teams selecting models for production use cases; adjacent to the $500M+ developer tools market; competes with Artificial Analysis and LMSYS Arena but with production data rather than synthetic tests.
MoatNetwork effects — more production traffic flowing through the system generates better rankings, which attracts more users who contribute more data.
