Agents - Agents SDK packages support AI SDK v6 and v7

Summary

Cloudflare Agents packages (agents, @cloudflare/ai-chat, @cloudflare/codemode, @cloudflare/think) now support both AI SDK v6 and v7. Existing applications can remain on AI SDK v6 when updating these packages, or adopt v7 without changing Cloudflare Agents APIs.

Key Points

• Supported peer ranges: ai@^6 || ^7 and @ai-sdk/react@^3 || ^4.
• Match major versions: pair AI SDK v6 with @ai-sdk/react v3, or AI SDK v7 with @ai-sdk/react v4.
• Think normalizes streaming, tool completion events, and telemetry across both SDK versions; v6 apps do not need to migrate integrations before updating Think.
• Existing Cloudflare Agents APIs remain stable when upgrading the packages.
