About Benchmark Index

Model launches come with a blizzard of numbers: each vendor picks the benchmarks it wins, reports them with its own harness, and the discourse fills with charts that can't be traced to a source.

Benchmark Index is the boring antidote: one place where every score is linked to where it came from, labelled by how well it's verified, and surrounded by the caveats that make it comparable — or not.

What this is not

We don't rank "the best model" and we don't take vendor money. When we haven't verified a number, we say so instead of guessing. Read the methodology for the full rules.

Who runs it

Benchmark Index is a Venture Factory experiment: a small product testing whether source-linked benchmark data is something people want weekly. The Benchmark Weekly newsletter is the heartbeat.
