One plugin, many providers — Anthropic, OpenAI, Google, Groq, Cerebras, Mistral, xAI, and more through Cloudflare's AI Gateway. Model ids take the form `provider/model-name` (e.g. `anthropic/claude-opus-4-6`), and keys live in Cloudflare's Secrets Store instead of your Worker config. Every call is cached, logged, and metered through the same AI Gateway that powers the rest of Cloudflare's platform.
