Proposed fix: [Vercel AI SDK] AI_UnsupportedModelVersionError 'Unsupported model version v1 for provider ... AI SDK 5 only supports models that implement specification version "v2"' - core ai and @ai-
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade ai and all @ai-sdk/* (and @ai-sdk/provider) packages together to matching majors; for community providers check their @ai-sdk/provider peer dependency; dedupe node_modules so frameworks and app share one ai version.
Option: Align ai and provider package majors [evidence: official_recommended_action]
Applies when: All AI SDK apps and frameworks
Steps:
1. npm ls ai @ai-sdk/provider to find duplicates
2. Upgrade ai and every @ai-sdk/* together
3. Replace unmaintained community providers or pin the previous major
Expected: Model spec version matches core
