CoreWeave Notebooks: Reactive Python Notebooks for AI
Oct 1, 2026

Summary
Introduces CoreWeave Notebooks, a new feature within CoreWeave Forge, leveraging marimo for reactive Python notebooks. These notebooks are designed for interactive AI development, enabling users to connect directly to project data and experiments. The post highlights their utility in debugging by identifying failure modes hidden in aggregate metrics (e.g., a driving model's performance degradation in specific weather conditions) and facilitating collaborative analysis through shared project storage. Future plans include publishing notebook views as persistent panels, hosting them as data apps, enabling direct model training, and integrating with ARIA for co-authoring.
