CloudflareDecisionModel unstable

Cloudflare Clef implementation of DecisionModel over Workers AI REST.

4 exports Since v4.0.0 Source

Constructors

make

unstable
Since v4.0.0

Builds a decision service with tolerance for four-decimal probability rounding.

Details

Base64 data is sent with its media type, and data: URLs are sent unchanged. Clef shows images before the state, so with images the state is sent as text that first lists each image's reference in order. The API enforces image limits.

Gotchas

  • Remote URLs fail with AiError.InvalidUserInputError because Clef does not fetch them.
