Adding Mistral Codestral and GPT-4o to Jupyter Notebooks
Hey HN! We’ve forked Jupyter Lab and added AI code generation features that feel native and have all the context about your notebook. You can see a demo video (2 min) here: https://www.tella.tv/video/clxt7ei4v00rr09i5gt1laop6/view Try a hosted version here: https://pretzelai.app Jupyter is by far the most used Data Science tool. Despite its popularity, it still lacks good code-generation extensions. The flagship AI extension jupyter-ai lags far behind in features and UX compared to modern AI code generation and understanding tools (like…
Adding Mistral Codestral and GPT-4o to Jupyter Notebooks launched on July 2, 2024 with 269 votes, #195 of 5,184 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Pretzel is a modified version of Jupyter Lab that integrates AI code generation directly into notebooks using Mistral Codestral and GPT-4o. Built for data scientists and developers who work in Jupyter, it provides native AI assistance with full notebook context, addressing the gap left by existing extensions. The tool is available as a free, open-source fork that can be installed locally or accessed through a hosted version.

WASM-powered codespaces for Python notebooks on GitHub2025 · docs.marimo.io · ▲204Hi HN! Last year, we shared marimo [1], an open-source reactive notebook for Python with support for execution through WebAssembly [2]. We wanted to share something new: you can now run marimo and Jupyter notebooks directly from GitHub in a Wasm-powered, codespace-like environment. What makes this powerful is that we mount the GitHub repository's contents as a filesystem in the notebook, making it really easy to share notebooks with data. All you need to do is prepend 'marimo.app' to any Python notebook on GitHub. Some examples: - Jupyter Notebook:…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
