We had our first ever launch week here at marimo. Five announcements in five days. Full recap ⬇️ marimo.io/blog/launch...

marimo is doing a launch week

One week. Five announcements. Can you guess what's coming?

Python is better than PowerPoint now. You can present marimo notebooks as slides. Widgets stay interactive and you can edit slides live while presenting. No more second window, separate demo, or crossing your fingers.

marimo is reactive, which means that it knows in what order variables are declared. So what if you had widgets at your disposal that could leverage that? For launch week, we're releasing some tools that do exactly this.

Ask and you shall receive: marimo now runs natively in PyCharm. Open, edit, and run reactive notebooks in @JetBrains without leaving your IDE. Install from the JetBrains Marketplace 👇

Open any marimo notebook on GitHub. Click one button. The raw Python turns into a live, interactive notebook you can run, right there in your browser. That's marimo Glance. Free extension for Chrome and Firefox, works on GitHub, gists, and GitLab. Details below.

Put a slider in one paragraph and the chart three paragraphs later. The Python cells stay connected. Reactive marimo cells now run inside Quarto, Jupyter Book, and anywhere MDX lives. quarto-marimo, jupyter-book-marimo, mdx-marimo, all open source. More below ⬇️

happy official launch day 1! launch week opens with updates to marimo-pair, now in VS Code. pair opens up a new medium for agent-native data and computational work: you + your agent, collaborating over one interactive, flexible canvas. more below ⬇️ marimo.io/pair

marimo pair — a thinking canvas for you and your agent

Give your agent a marimo notebook. The ease of chat, the rigor of software.

SciPy was a blast! Missed Trevor Manz's anywidget talk or Dylan Madisetti's caching poster? Not to fear, for our first ever launch week is here...5 new announcements next week. What are you hoping it'll be?

I finally tried out the @marimo.io marimo-pair skill to do some light data analysis and plotting in conversation with an LLM and it really worked. Tedious plotting layout and syntax fadeed into the background. I used OpenCode + GLM 5.2, @pola.rs and @matplotlib.org Would recommend. #EnergySky

A four-panel plot showing advanced metering deployment in Pennsylvania. The first panel shows how market penetration has changed over the years by customer class (residential, commercial, and industrial) with all classes approaching 100% penetration in recent years. The lower 3 panels show the percentage breakdown between standard (dumb) meters, one-way, and bidirectional advanced meters by customer class and year.

molab has free GPUs and we've been exploring the different ways that you could use them. And there's plenty to do outside of deep learning! You can use them to tackle TSP problems too. But it helps to rethink your CPU-based algorithms when you go here. youtu.be/1-5wkzdP1Jc

How to Throw a GPU at a Problem

If you have a GPU, sometimes it helps to dumb-down the algorithm. I...

Now that molab has free GPUs we started toying with ideas that aren't 100% practical but might teach us something. So we asked a question: can we use deep learning to solve (NP)-hard computer science problems? Details are in the video below: youtu.be/QnP-EdJyiDo

What actually makes a notebook win? We just extended our competition with @askalphaxiv to July 8, so here's the breakdown.

FastAPI Cloud hit public beta and since marimo notebooks are just Python files under the hood, you can deploy one there too. Vincent Warmerdam live-codes it: create_app to fastapi deploy to "hello from marimo" live on the web. A fun party trick in 4 minutes ⬇️

A room of English majors and CS majors, half of whom had never written a line of code. By the end of the semester, every one of them had fine-tuned GPT-2. How University of Pittsburgh Teaching Associate Professor Matt Burton rebuilt his course around marimo → marimo.io/blog/case-s...

double descent is one of the most counterintuitive results in deep learning, and you can't really show it on plain MNIST. MNIST-1D can. huge thanks to @samgreydanus & @hippopedoid for the paper on @askalphaxiv. new video reproduces it from scratch 👇

How does South Africa's largest telecom provider keep 15,000 mobile network sites running through rolling blackouts, across millions of telemetry records a day? At @Vodacom, Dr. Jaco du Toit does it with marimo notebooks. Full case study 👉 marimo.io/blog/case-s...

Did you know your birthday is somewhere in the digits of pi? We built a marimo notebook that finds the exact digit where yours shows up. Full video below 👇

We ran a competition where you had to implement a research paper and make it interactive. Round two is live, this time with GPU access on molab. Pick any alphaXiv paper, build a marimo notebook, win a Framework Laptop 13, Claude subscriptions, and more. Deadline: June 28 👀

running 2,000 training runs and reporting the best one isn't better science. it's loading the dice. the curse of optimality from @askalphaxiv explained below:

Day 5 of our "What can you do with a GPU on molab?" series. Does adding reasoning to open source LLMs actually improve accuracy? Video in the comments ⬇️

Day 4 of our "What can you do with a GPU on molab?" series: In comparison to other free GPUs, molab cuts the time it takes to do an Unsloth fine-tuning job by 2/3. Video below:

Day 3 of our "What can you do with a GPU on molab?" series: how long does it take to solve the Traveling Salesman Problem with 2-opt on a GPU? Hint: it's faster than you can say "500 cities in half a millisecond." Video below ⬇️

It's our first time hosting an event at #NYTechWeek. 📍Tomorrow, 1 PM EST. Join Myles Scolnick and Trevor Manz as we chat through what we've been building lately, all with a side of ice cream. Our event is at capacity, but our waitlist is open. RSVP in the comments ⬇️
