Notion has integrated GPT-5.5 into its AI suite, giving users access to OpenAI’s latest frontier model directly within their workspace.

This update keeps Notion at the bleeding edge of LLM capabilities, offering GPT-5.5 as a high-performance alternative for complex reasoning, advanced coding, and nuanced content generation. By including this model in the “Beta” lineup, Notion allows power users to leverage GPT-5.5’s improved logic and expanded context window for tasks that require deep synthesis of workspace data.

To enable this, open the Notion AI chat or an Agent’s settings, click on the current model selection and select GPT-5.5 from the dropdown menu. You can toggle this model on a per-chat basis to compare outputs and find the best fit for your specific workflow.
