Price / context / lifecycle changes
API pricingChanges
Every price, context-window, and deprecation change we’ve tracked for an AI model, with provenance. An event only counts when a publishable source (LiteLLM or models.dev) actually moves a value — OpenRouter feeds our cross-check but never mints an entry here (its terms bar republication; disagreements are flagged on /models/pricing instead). The ledger is append-only: nothing here is ever edited or deleted, only added to.
