Open-source database of AI models, prices and capabilities
Every model uses a consistent provider/model format so the same model across providers can be compared directly.
Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
Input and output prices per million tokens listed alongside release and update dates.
Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
A free archive of how every AI model answered the same 100 questions
One hundred identical questions covering drawings, websites, writing, images, code and audio, each answered by every model and kept as given.
121 of the 385 models are no longer served on OpenRouter, yet their answers remain viewable, preserving outputs that would otherwise be lost.
Add two to four models with a single click and view their answers to the same questions next to each other.
Explore a magnifiable globe of answers, an index sortable by release date, lab or question, a monthly timeline, and a fast command-K search.
