What they do

Problem

Organizations lack trustworthy, contamination-proof benchmarks to accurately compare real-world performance of large language models.

Solution

LLM Stats provides an independent LLM leaderboard and runs contamination-resistant evaluations with an archive of benchmark results.

Who it's for

AI researchers, developers, and organizations selecting or monitoring LLMs use it for transparent model comparison.
