PyCharm 2026.2 introduces significant AI integration, allowing AI agents to work directly within Jupyter notebooks using a live kernel. This persistence of variables and models improves reliability for machine learning workflows. The release also addresses package management issues by ensuring AI agents install packages into the correct project environments. Marimo notebooks are now supported via a new third-party plugin, enabling reactive cells and interactive UI elements within the IDE. To enhance performance and focus, PyCharm is unbundling less-used plugins like Data Wrangler and Hugging Face. The Python Packages tool window has been redesigned for better dependency visualization and faster package management. Type checking messages are now clearer and more actionable with detailed breakdowns of mismatches. Virtual environment creation for end-of-life Python versions is no longer supported. SQLAlchemy 2.0's Session.get() inference has been improved for better model instance recognition. These updates are available in PyCharm 2026.2.1 and aim to provide a more streamlined and powerful development experience, particularly for AI-focused projects.
