which-llm

Artificial Analysis needs to step up their game.

Artificial Analysis has a ton of data on language models. which-llm makes that data available to an agent, so I can ask about the models, compare them, and make charts like this one:

which-llm Pareto chart plotting intelligence index against benchmark task cost from the September 30, 2026 UTC refreshed snapshot

It combines the benchmarks with OpenRouter prices, context windows, supported inputs, and the model names you pass to the API. You can ask for a fast model that can read images, compare a few specific models, or see how much intelligence you're giving up to spend less.

The data refreshes daily, enjoy.
