createAI has no evaluation model, so Clef (@cf/cloudflare/clef, @cf/cloudflare/clef-flash) can't be used with the AI SDK's experimental_evaluate (EvaluationModelV4, ai@7.0.103+).

const ai = createAI({ binding: env.AI });
const { answers } = await evaluate({
  model: ai.evaluation("@cf/cloudflare/clef"), // doesn't exist
  state: "Checkout has been failing for every customer for the last hour.",
  questions: { urgent: { type: "boolean", instructions: "Is this urgent?" } }
});

The modality methods live in packages/agents/src/models/ai-sdk/index.ts and ai-sdk/models/modality.ts; there is no evaluation alongside embedding, image, speech, transcription and reranking. cloudflare/ai#670 has a working EvaluationModelV4 for the old package (maps boolean to Clef's noul, forwards images, exposes confidence and legend in provider metadata) that could be ported.

From cloudflare/ai#670.
