Claude Fable 5.2 now available in AI Gateway and Agent Runners

Netlify made Claude Fable 5.2 available in AI Gateway with no configuration. Use the model ID claude-fable-5-2 alongside the other Claude models already offered there.

In a Netlify Function, create the Anthropic SDK client with new Anthropic() and call messages.create with that model. You don't manage API keys or authentication, because AI Gateway handles them.

It also works in Scheduled Functions, Background Functions, and Edge Functions, with Netlify's caching, rate limiting, and authentication infrastructure applied automatically.
