Proposed fix: [Mastra] Agent.generate()/stream() reject AI SDK v4 providers: "is using AI SDK v4 model ... which is not compatible with generate(). Please use AI SDK v5+ models or call the generateLeg
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade @ai-sdk/* provider packages to AI SDK v5/v6-compatible versions (or use Mastra model router strings), or temporarily call generateLegacy()/streamLegacy(); for unrecognized versions, align the provider with a spec your Mastra version supports.
Option: Align provider package with Mastra-supported spec [evidence: official_recommended_action]
Applies when: Version mismatch
Steps:
1. npm i @ai-sdk/openai@<v5/v6-compatible>
2. or agent.generateLegacy(...) temporarily
Expected: generate()/stream() work
