Question

Which ai package versions does agents support as a peer dependency?

Answer key

A correct answer says
agents, @cloudflare/ai-chat and @cloudflare/codemode support both AI SDK v6 and v7 (`ai@^6 || ^7`, `@ai-sdk/react@^3 || ^4`); AI SDK v5 is not supported. @cloudflare/think now requires `ai@^7` only.
The stale answer
agents requires AI SDK v5 (or v6 only).

Answer

The installed `agents` (0.27.0) declares `"ai": "^6.0.0 || ^7.0.0"` as a peer dependency, so it accepts AI SDK v6 or v7. Its `peerDependenciesMeta` marks `ai` as optional, so it only matters if you use the parts of `agents` that rely on the AI SDK. The related `@ai-sdk/react` peer accepts `^3.0.0 || ^4.0.0`. `ai` isn't currently installed in this project's `node_modules`.

Answering cost $0.11.

Grade

correct

The judge's reason: It states agents supports ai ^6 || ^7 and @ai-sdk/react ^3 || ^4, matching the key, with no stale v5 claim.
