Notion has integrated OpenAI's GPT-4.1 and Anthropic's Claude 3.7 into its platform, enhancing its AI capabilities for enterprise users. This integration includes a model selector allowing users to switch between these models and Sonnet 3.7 within the Notion workspace, aiming to reduce context switching and improve productivity. The new features include AI meeting notes, enterprise search, and a research mode that can generate new pages based on research. Notion's AI for Work can track and transcribe meetings, and the enterprise search connects to various apps like Slack, Microsoft Teams, GitHub, Google Drive, Sharepoint, and Gmail. GPT-4.1 is noted for its effectiveness in everyday tasks such as brainstorming, summarizing, and creative content creation, while Claude 3.7 offers a hybrid model capable of both regular LLM and reasoning tasks. Notion has fine-tuned these models to ensure accuracy, safety, privacy, and speed for enterprise needs, positioning itself as a one-stop AI knowledge work platform.
