Notion Adds Grok 4.5 With Gains on Search-Heavy Tasks.

Notion announced that Grok 4.5 is now available inside its workspace platform. The company positions Grok 4.5 as the strongest Grok model it has tested, highlighting an improvement over Grok 4.3 with particular gains on search-heavy tasks.

The announcement, shared via LinkedIn, marks the latest AI model integration for Notion, which has steadily expanded its AI capabilities over the past year. The update follows recent additions including Claude Sonnet 5 and HTML blocks for interactive content creation.

Notion did not provide specific benchmarks or performance metrics for Grok 4.5, nor did it detail which types of search-heavy tasks show the most improvement. The brief announcement suggests the rollout is already live for users.

Grok 4.5 is developed by xAI, the AI company founded by Elon Musk. The model's availability in Notion gives users another option alongside existing AI providers like OpenAI and Anthropic. For teams that rely heavily on search and information retrieval within Notion workspaces, the upgrade could translate to faster, more accurate results when using AI features.

Notion has been building out its AI infrastructure significantly. The company recently launched its Developer Platform, which includes Workers for syncing external data sources and custom tools for Notion Agents. These tools allow developers to build integrations that generate assets, query live data, and connect to external APIs directly within Notion.

The addition of Grok 4.5 fits into this broader strategy. As Notion builds more developer tools and agent capabilities, having access to multiple AI models gives users flexibility to choose the best fit for their specific workflows.

Notion's quick adoption of Grok 4.5 reflects the accelerating pace of AI model releases and enterprise integration. Companies are no longer waiting months to evaluate new models before making them available to users. The speed of this rollout suggests Notion has built infrastructure to test and deploy new models rapidly.

For small business owners and teams using Notion, the practical impact will depend on how they use AI features. Search-heavy tasks might include querying large databases, retrieving specific information from documentation, or synthesizing insights from multiple pages. If Grok 4.5 delivers meaningful improvements in these areas, it could make Notion AI more useful for knowledge management and research workflows.

Notion has not announced pricing changes related to Grok 4.5 availability. Users with access to Notion AI features should see the new model as an option in their workspace settings.
