Company
LLM Stats
Independent AI evaluations lab
We build independent, contamination-proof benchmarks that measure real-world performance of large language models. Our product is the most complete LLM leaderboard, archiving all benchmark results and running new evaluations that avoid the classical tests found in models' training data.
We live and work in New York, NY. The company would remain based here after YC.
We chose New York because it's where we're based and where we understand the community of AI users and developers who need transparency in model evaluation.
