This release focuses on performance improvements and AI capabilities, making marimo notebooks faster and more intelligent.
✨ Highlights
Configure "Displayed models" in the AI configuration
The new AI Model Configuration interface (#6140) allows users to customize which models appear in their AI dropdown, providing better control over models used for development.
Add "Notebook Errors" as a context in any AI input
marimo copilot can now include notebook errors as context when you ask for help (#6158), making debugging faster and more intuitive.
When your code encounters issues like missing tables, import errors, or other exceptions, simply ask the AI chat "Can you help me fix these @Errors" and it will analyze the complete error context - including tracebacks, error messages, and relevant code - to provide targeted solutions.
