OpenAI's model GPT-5.1 is now available in Retool. It can be used with AI actions and with Retool Agents.

Retool now supports Azure OpenAI for use with Assist. Admins on the Enterprise plan can configure Assist to use Azure OpenAI as the single model provider for Assist-powered interactions.

Retool designed Assist to use two AI providers by default: OpenAI and Anthropic. Using both providers enables Assist to optimize for speed and quality. However, some customers may need to consolidate AI services with a single provider. To accommodate these customers, Enterprise organizations can configure Assist to work with a single provider.

Retool no longer supports Claude Sonnet 3.5. Claude Sonnet 4.5 will be used instead.

Retool no longer supports GPT 3.5 Turbo. GPT-4o-mini will be used instead.

Retool now supports Amazon Bedrock for use with Assist. Admins on the Enterprise plan can configure Assist to use Amazon Bedrock as the single model provider for Assist-powered interactions.

Claude Haiku 4.5 is now available in Retool. It can be used with AI actions and with Retool Agents.

Users can now modify the order of pages in multipage apps. In the Pages tab in the left panel of the app IDE, users can sort pages relative to each other using drag-and-drop.

Changes to the page order are immediately reflected in the page menu (and in header and sidebar frames if present). The retoolContext.pages Javascript variable also provides the list of pages in order.

An open source AI model available through Baseten, Kimi K2 Instruct is now available in Retool. It can be used with AI actions and with Retool Agents.

Retool no longer supports the Llama 4 Maverick or Llama 4 Scout AI models in Retool AI. The Kimi K2 Instruct model will be used instead.

Retool has released several improvements to the README experience for web apps:

• The README is now located at the top of the Pages or Screens list for easy access.
• Cloud instances can now use AI to generate a README automatically based on the components and logic of your app.

Previously, app READMEs were found by clicking the title of the app. If your app has an existing README, you can now find it in the Pages tab.
