Side-by-side comparison
Compare AI Models
Pick two to five models. Every cell comes from a verified record; anything unverified says so. There is no overall winner — the right choice depends on your task, budget and technical needs.

The example cost multiplies the published per-1M-token list prices by the token counts above. It ignores caching, batch discounts, long-context surcharges and tax, and is shown only when both rates are verified.
How to choose
Start from the rows that matter for your job: a free plan and learning curve for casual use; API access, rates and data terms for building products; context window and modalities for long documents or images. Provider claims are labelled as such; we do not rank.
