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.
• You 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.

You can now connect any AI provider that adheres to the OpenAI, Anthropic, Google, or Cohere schema. This enables you to connect from a wide range of AI providers, such as Mistral, Fireworks AI, Together AI, and OpenRouter.

Organizations with increased security and compliance requirements can also configure custom AI providers if they need to route traffic through their own proxies.

Retool now supports with Amazon Bedrock and Knowledge Bases for Amazon Bedrock. This integration enables businesses to leverage the power and security of Amazon Bedrock with the ease and speed of development on Retool to build AI applications.

For companies with strict data policies, sending data to a third-party LLM is a deal-breaker. With Amazon Bedrock, businesses can host LLMs within their VPC, ensuring compliance with their security and governance requirements. Retool customers who have adopted AWS can take advantage of all that Bedrock has to offer while keeping their data safe and secure.

OpenAI's new flagship model, GPT-4o, is now available for use in Retool AI actions.
