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.

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

Retool no longer supports Gemini 1.5 Pro. Gemini 2.0 Flash will be used instead.

Retool AI* text action queries now support dynamic model selection. Clicking the Fx button next to the AI Model field in a query will display the model string in the following format: providerName::model-name, for example, openai::gpt-4o-mini. This provides the ability for users to dynamically change AI models from apps and workflows.

Retool Vectors now supports adding filter labels, and metadata to vector resources.

Retool AI supports using filters and metadata to query Retool Vectors with the Generate text, and Generate chat response AI actions.

Retool Vectors can be queried from Retool Apps or Retool Workflows using AI Actions.

An OpenAI reasoning model, o1, is now available for use in Retool AI actions.
