marimo now exposes its AI tools through an MCP server endpoint, allowing external AI applications like Claude Code, Cursor, and VS Code to interact with your notebooks.

**Just shipped: v0.17.0** 🍃

v0.17.0 improves the developer experience of working with AI, lets you use marimo as an MCP server, and adds support for Python 3.14.

One of many features: our AI autofix automatically injects table and runtime context for you.

Release 0.16.0 delivers multi-cell AI code generation and common error detection/reporting before runtime.

The "Generate with AI" feature now can create multiple cells at once and run marimo check to identify issues such as multiple definitions, circular dependencies, and syntax errors.

Learning is better when it’s interactive.

The CodeCut newsletter by Khuyen Tran delivers Python and AI tips, 3 times a week, and now each issue includes a "Run Code" button. With one click, you can launch a molab notebook and experiment with the examples directly in your browser.

The Python Discord community just finished their annual code jam: create a browser-based application that is written almost entirely in Python that incorporates the theme of "wrong tool for the job."
One of our favorite submissions is Tetris Bugs. You fit falling code blocks into working programs.

Sasha Rush from Cursor created these Tensor puzzles to help people learn PyTorch. They're fun and interactive with immediate feedback from cute dogs!

We have better LLM configuration now!

molab Run Mode
When sharing, simply add /app to the end of your notebook URL so anyone can interact with the notebook live, even users not in your workspace. You also don't need to worry about overusing compute due to persistent caching and storage.

"I could buy the new iPhone 17 Pro Max with the compute cost from running this code."

No worries, we have persistent caching/storage in molab, our cloud-hosted Python notebook workspace, so you can buy all the phones you want!

Many of you asked for VS Code integration so here's a sneak peek!

We previewed this along with other exciting features at our community call this past weekend, check out the full call here: youtu.be/3caIs0jWykc

Our latest release introduces several conveniences for exploring and visualizing in-memory objects, along with bug fixes. We also improved ibis integration (portable dataframe library) with native marimo support, all thanks to Kyrre Wahl Kongsgård!

We're making widgets for image-related tasks!

First up is annotation, so stuff like this:
