AI module integration with Cloudflare Workers AI and fal.ai, providing text generation, image generation, and more
The AI module delivers end-to-end AI capabilities through TanStack AI and Cloudflare Workers AI, with deep integration of TanStack AI's fal adapter (@tanstack/ai-fal) for image generation and editing.
Setup
| Environment Variable | Description |
|---|---|
CLOUDFLARE_ACCOUNT_ID | Cloudflare account ID for Workers AI REST calls |
CLOUDFLARE_API_TOKEN | Cloudflare API token with Workers AI > Read permission |
FAL_KEY | fal.ai API key for image generation, create one in fal.ai Dashboard |
All Workers AI calls go through the REST API, so no Workers Binding configuration is needed — they work in CI and external runtimes too.
If you are setting up your environment, you can now go back to the Environment Configuration and continue. The rest of this document can be read later.
