Pricing

The price a lab's own page showed on the day that page was captured. That is what a snapshot can prove; it is not necessarily the launch price, and prices are often cut later. Citing the live pricing page instead would give a number with no date at all.

Input $3 per million tokens observed June 20, 2024 · archived snapshot (2024-06-20)
Output $15 per million tokens observed June 20, 2024 · archived snapshot (2024-06-20)

This record is a historical one: every figure above is traced to a dated primary source. For what is true today — live pricing, current rankings, availability — these are better maintained than anything here could be.
