<p>Report of the Project Jupyter Mini Summit on 6 Oct 2026 in Prague</p>

<p class="standalone-image"><img src="https://blog.jupyter.org/posts/2026/highlights-from-the-project-jupyter-mini-summit-2026/images/rylMgPMa3fx.jpg" alt="2026_10_06_prague_group" loading="lazy" data-body-image=""></p> <p>On October 6, 2026, contributors, users, and community members came together in Prague for the <a href="https://osselceu2026.sched.com/event/2RjI5">Project Jupyter Mini Summit</a>, held as a satellite event of <a href="https://events.linuxfoundation.org/open-source-summit-europe/">Open Source Summit Europe 2026</a>.</p> <p>The three-and-a-half-hour gathering brought together a diverse program of talks and community conversations, around new developments and opportunities for Project Jupyter.</p> <h2 id="a-whirlwind-tour-of-the-jupyter-ecosystem">A whirlwind tour of the Jupyter ecosystem</h2> <p>The session began with a broad introduction to the <strong>Jupyter ecosystem</strong>, with <a href="https://github.com/sbonaretti">Serena Bonaretti</a> presenting the people and the projects that constitute Project Jupyter (<a href="https://zenodo.org/records/23494522?preview_file=2026_10_06_Jupyter_minisummit_welcome.pdf">slides</a>).</p> <p>The first session focused on <a href="https://jupyterlab.readthedocs.io/en/latest/"><strong>JupyterLab</strong></a>, with <a href="https://github.com/krassowski">Mike Krassowski</a> discussing the latest features in version 4.6 and the tooling and development practices behind its development (<a href="https://github.com/krassowski/mini-summit">slides</a>); <a href="https://jupyterlite.readthedocs.io/en/stable/"><strong>JupyterLite</strong></a>, with <a href="https://github.com/jtpio/jtpio">Jeremy Tuloup</a> tracing its evolution from an early proof of concept to deployments at significant scale (<a href="https://github.com/jtpio/jupyter-mini-summit-2026">slides</a>); and <a href="https://jupyterhub.readthedocs.io/en/stable/"><strong>JupyterHub</strong></a> and <a href="https://jupyterbook.org/"><strong>Jupyter Book</strong></a>, with <a href="https://github.com/sbonaretti">Serena Bonaretti</a> reflecting on the experience of managing their communities (<a href="https://zenodo.org/records/23494522?preview_file=2026_10_06_JH_JB_communitymanager.pdf">slides</a>).</p> <p>The second session covered <a href="https://github.com/jupyter-infra/jupyter-deploy"><strong>Jupyter Deploy</strong></a>, with <a href="https://github.com/JGuinegagne">Jonathan Guinegagne</a> exploring approaches to bringing interactive computing to cloud environments, and <a href="https://jupyter.org/security"><strong>Jupyter Security</strong></a>, with <a href="https://github.com/Yann-P">Yann Pellegrini</a> highlighting the challenges and practices involved in coordinating security across a large and diverse open source ecosystem (<a href="https://github.com/Yann-P/oss-prague-2026-jupyter-security">slides</a>).</p> <p>All presentations are available on <a href="https://www.youtube.com/playlist?list=PLbJk0fi9gFmE">YouTube</a>.</p> <h2 id="ai-of-course">AI, of course!</h2> <p>AI was a recurring theme throughout the summit, featuring prominently in many of the discussions and projects presented.</p> <p>JupyterLab and JupyterLite allow the embedding of large language models into interactive computing workflows, bringing AI-assisted capabilities closer to the environments where users write code, explore data, and develop computational narratives.</p> <p>On the other side, the new project <a href="https://whybook.dev/">Whybook</a> by <a href="https://github.com/krassowski">Mike Krassowski</a> is a view of a Jupyter notebook with no chat box but suggested recommendations and choice behind the results.</p> <p>AI is also increasingly relevant to security, as there has been a fourfold increase in reports volume since the beginning of the year.</p> <h2 id="the-importance-of-hosting-jupyter-events-in-europe">The importance of hosting Jupyter events in Europe</h2> <p>One of the main takeaways from the summit discussions was that <strong>there is real value for in-person events in Europe</strong>. This reflects how much the community values opportunities to share ideas, learn from one another, and connect in person throughout the year, while remaining mindful of the <strong>environmental impact of travel</strong>.</p> <p>London and Paris stand out as particularly appealing locations for future events, as many Jupyter contributors are based in or around these cities.</p> <h2 id="a-spatial-room">A spatial room!</h2> <p>As the personnel of the conference center enthusiastically told us, we were in the very room that served as <strong>mission control in the movie <em>Astronaut</em></strong> with Adam Sandler (2024)! What better setting for Project Jupyter?</p> <figure> <img alt="Project Jupyter Mini Summit 2026 venue" src="https://blog.jupyter.org/posts/2026/highlights-from-the-project-jupyter-mini-summit-2026/images/HJvHuxFnGg.webp" loading="lazy" data-body-image=""> <figcaption>Our summit room, set up as a mission control in the movie “Astronaut” (left); view of Prague from the 4th floor of the conference center, where the room was located (right).</figcaption> </figure> <div class="main-content-end" aria-hidden="true"></div> <h2 id="thank-you-and-see-you-at-compute-paris-2026">Thank you and see you at Compute! Paris 2026</h2> <p>Thank you to everyone who joined us, contributed a talk, shared a project, asked a question, or simply took the time to be there!</p> <p>The next opportunity to connect will be <a href="https://compute.events/paris2026/">Compute! Paris 2026</a>, a new annual conference dedicated to open source computing and data, taking place November 25–26, 2026 at Sorbonne Université in Paris. <strong>Jupyter will have a <a href="https://blog.jupyter.org/posts/2026/jupyter-compute-paris-2026/">strong presence</a> at the event</strong>, with a keynote by Fernando Pérez and a dedicated Jupyter track on the second day. There will also be Jupyter-focused sprints on November 27, the day after the conference. The sprints are free to attend and open to everyone, independently of conference registration. Looking forward to seeing you there!</p>
