Methodology

How this ranking is built

Active models with a verified context window on file. Ranked from largest window down. Output price is shown alongside because long-context workloads tend to produce a lot of output too.

Refreshed as we re-verify each model against its provider's official docs. Every value links to the page it came from. Last updated Jun 3, 2026 20:23 UTC.
