Introducing CoreWeave Notebooks for Interactive AI Development
CoreWeave, Thursday, October 1st, 2026
CoreWeave Notebooks, built on marimo, bring reactive Python and SQL notebooks connected to experiments and evaluation data into Forge.
CoreWeave announced CoreWeave Notebooks, now available in CoreWeave Forge, which open from a project already connected to its experiments, artifacts and evaluation results and offer Python and SQL for custom analysis beyond standard dashboards.
They run on marimo, the open source reactive Python notebook, so outputs always reflect current code without stale cells, and they are saved to the project so teammates can copy and build on them.
A demo shows slicing a driving model's loss by weather and time of day to reveal failures at night in rain that aggregate metrics hid.
