AI Change Watch

What is AI Change Watch?

Vendor changelogs are prose, and never record what a number used to be. AI Change Watch re-reads the pricing, model, API and security pages of 15 AI providers on a schedule and records each change as an exact before → after diff, with its source. It also publishes what that record makes possible: price history and a market price index, model-vs-model comparisons, a calendar of shutdown dates with successors and migration cost, and findings like "only 66% of retirements name a replacement".
