What it does
Claude Fable 5.2, from Anthropic, is built for technical work such as coding and reasoning. Vercel says it can run long, open-ended tasks without supervision.
Who it's for
Developers and teams building software or tools that use AI models through an API.
Price and where to try it
Vercel says AI Gateway passes provider prices through with no markup. The item gives no price for the model itself. Use it through the AI SDK, the Chat Completions or Responses APIs, or a coding agent.
