Side by side

Compare two AI models

Pick two models and see what each costs, how well it works and what it's actually for. The scores are my own judgment on a 1–5 scale from using these — not vendor claims and not benchmark results. Your picks stay in the address bar, so you can send the comparison to someone else.

Free models plus pay-as-you-go access to hundreds more, prices side by side.

Published benchmark scores: No published score. OpenRouter is the shop, not the product: it ranks models by how much real developer traffic they get and republishes Artificial Analysis scores. It makes no capability claim of its own.
Cost: Free models and free sign-up; paid use adds a 5.5% fee on credit top-ups.
Performance: Hundreds of models behind one interface with prices side by side — the quickest way to see what a model actually costs per use.
