How to read this page
The figures are the list prices published on the vendor's own pricing page, re-read every week by an automated check that never invents a number: if the page cannot be read, the previous reading is kept and the item is flagged after three missed weeks. Negotiated rates, volume tiers, free credits and regional pricing are not modelled. The methodology describes the process and its limits; the price index shows every llm api figure side by side.
