Changelog

Retool introduced several features to help Enterprise organizations manage AI token spend when using their own API key for AI resources.

Use the new Get BYOK AI token usage endpoint to measure the number of tokens consumed for each AI resource that uses your own key. You can view the number of tokens consumed by resource, user, and surface area.

In addition, you can also view BYOK AI token usage in Settings. Navigate to the Usage Analytics page, and click the AI tab. You can filter AI usage by model, user, and feature.

Self-hosted Retool instances can now connect to Gmail as a resource to read, send, and manage email using the Gmail API.

Self-hosted instances authenticate using your own Google Cloud OAuth client, so this integration is available now without waiting on Google's app-verification process for Retool's shared OAuth client.

The app builder now supports multiple chat conversations (threads) working on the same branch rather than a single thread per branch.

A thread is a single chat conversation with the agent in the Chat tab. Threads are intended to help you keep your work organized by task or theme. For example, use one thread for updating your app theme, and another thread for editing a chart on that page. Manage threads from the Chat tab.

A branch is a set of changes to your app, associated with an app preview, and with its own change history. A branch is the unit of work that you publish, and you create a new branch to begin a distinct line of work. For example, create a new branch when you want to change the resources that your app uses, or when you want to overhaul a page. Manage branches from the Change History tab in the navbar.

When using Source Control, branches in the protected app builder map to branches in your external git repository.

Claude Opus 5 is now available to cloud organizations through Anthropic. It can be used with AI resource queries, with Retool Agents, and in Assist. Opus 5 requires you to bring your own key for AI resource queries and Assist; Retool Agents can use Opus 5 with a Retool-managed key. Support for self-hosted Retool is coming in an upcoming release.

Retool is deprecating versions 1.0 and 2.0 of the Microsoft SQL integration. Organizations with Microsoft SQL resources still using these versions must update their resource configuration to use version 3.0.

This deprecation will first take effect on cloud instances on August 24, 2026. It will then take effect in the next edge and stable releases that follow.

Version 3.0 has been available since February 2, 2026 for cloud instances and the 3.334 stable release. If you haven't intentionally created a resource on an older integration version, your resource is likely already on version 3.0 and requires no changes.

To upgrade an existing resource, open its settings from the Resources page, change Connector version to Version 3.0, and save your changes.

Versions 1.0 and 2.0 will be removed entirely from cloud instances in Q4 2026, followed by the subsequent edge and stable releases. After that, apps, workflows, and queries that depend on Microsoft SQL resources still using version 1.0 or 2.0 will stop working.

For Enterprise organizations that use Source Control to protect apps, you can now use the app builder to check out a branch that you created outside of Retool. This enables you to transition your changes from a local development environment to the app builder. This can be useful for visually validating your changes in the preview canvas.

When prompting in the Chat tab of the app builder, the agent asks clarifying questions to better understand your intent and create your desired outcome. The agent can ask multiple-choice or open-ended questions.

You can now build apps with more AI models: Claude Sonnet 5, the GPT-5.6 models (Sol, Terra, and Luna), and Claude Fable 5. Choose a model for each thread in the app builder's Chat tab. Admins can set the organization's default app building provider and model in the AI settings.

Claude Sonnet 5 can be used on paid plans with a Retool-managed key or your own key. The GPT-5.6 models and Claude Fable 5 require you to bring your own key, which is available on the Enterprise plan.

Retool 4.27 is now available on the Edge release channel for self-hosted organizations.

The following patches are now available on the Stable release channel:

• Retool 4.0.7
• Retool 3.334.25
• Retool 3.334.24
• Retool 3.300.34
