marimo

marimo brings your data to life! Select points in a plot and get them back in Python, instantly, with reactive charts. In this data app, a reactive chart lets the user interactively explore the original images backing a 2D embedding of MNIST.

Kimi K2.6 (hosted via @wandb's inference engine on @CoreWeave) hits 120 tokens per second. Fast enough to build the whole notebook before you've finished reading the first cell. But is it...too fast? Full vid out now ⬇️

This was fun! Meeting the marimo team + PyCon US. marimo team is hiring too! marimo.io/careers

If you can vibe code anything these days ... do we still need notebooks? We're going live in 24 hours to find out with @HamelHusain to discuss. 🗓️ May 22, 2026 at 1 PM PST. Link below ⬇️

marimo runs as a web app you can open from any machine. We didn't design it for the Steam Deck...but it works there, and it turns out the controllers are a surprisingly good fit for data annotation. Video linked below ⬇️

We're big @DataPolars fans at marimo. The Polars team has been working on something new: it's early, it's fancy, and it ships with a few features that are directly relevant to marimo. Livestream with @thijsnieuwdorp on May 22, 2026. Link below ⬇️

We invited @isaac_flath to stress-test marimo-pair: can a reactive notebook actually give agents the same live kernel access that makes RLMs work? Agentic coding, live bugs, and how much time people spend playing World of Warcraft. More in the full video ⬇️

We're doing an extra livestream this week with @HamelHusain Small hint: it'll be about notebooks. youtube.com/live/XaKvqdOJl…

Thanks for putting on such a great conference!

Come find us at PyCon! We have a booth all weekend and would love to meet you ☺️ P.S. our very own @themylesfiles is hosting a talk later today. Join us to learn "How to port a Python kernel to Pyodide for a blazingly fast in-browser coding experience." See you there!

Ask an LLM to pick a random number and odds are, it's not random. The biases in models make generative outputs repetitive. Turns out you can improve output diversity through a thought prompting trick. Tutorial below ⬇️ Paper by @SakanaAILabs
