CopilotKit 1.78.0 released
A feature release that enables automatic trajectory capture for learning objects and improves OpenAI API handling.
What changed in 1.78.0
- Trajectory capture now starts automatically for learning objects on mount.
- OpenAI API choice is now controlled by COPILOTKIT_OPENAI_API environment variable; slash model IDs work correctly with OpenAI-compatible endpoints.
- GoogleGenerativeAIAdapter defaults to gemini-3.5-flash model.
- Features remain enabled if entitlement lookup times out; debug logging improved for thread lookups.
Check before you update
- Learning objects without trajectoryId now auto-start capture; add autoStart: false to preserve manual control.
- With OPENAI_BASE_URL set to non-OpenAI hosts, openai model strings now use Chat Completions API instead of Responses API; set COPILOTKIT_OPENAI_API=responses to restore Responses API behavior.
