## @ai-sdk/groq 4

### Security

- @ai-sdk/provider-utils has an Uncontrolled Resource Consumption issue (4.0.33) — [security advisory](https://github.com/advisories/GHSA-866G-F22W-33X8)

### New APIs and options

- The reasoning level type now includes max. Third-party providers and consumers with exhaustive mappings must handle the new value; existing reasoning levels remain accepted. (4.0.56) — [release notes](https://github.com/vercel/ai/releases/tag/%40ai-sdk/groq%404.0.56)
