  title: ArtificialWatch open data Releases API
  version: 1.0.0
  summary: AI model releases and shutdowns, first-party LLM API prices, published knowledge cutoffs, open-weights models, OpenCode's stealth models and leaderboard indexes as static JSON, CSV and iCalendar files.
  description: 'Read-only, keyless, CORS-open files at stable URLs: the AI model release log (dated by the day each model went live on a public API), each live model''s list price on its maker''s own API, the composite Bench and Coding indexes across public leaderboards, first-seen versus announcement times, every dated model shutdown from the labs'' own deprecation pages, the knowledge cutoff each lab publishes for its live models, every open-weights model with its Hugging Face repo, licence, size and rank, and every anonymous model OpenCode has listed with the lab that later claimed it. Files refresh with the site (about every 4 hours). Licence CC BY 4.0: credit ArtificialWatch with a link to the page named in each file''s `url`. Each board''s raw scores belong to that board.'
