  3. From the model picker, select one of the available models. 

    Once Brain has responded using one model, you can pick a different model without leaving the conversation!

Switch AI models mid-chat from Brain

Each model keeps the full conversation history and your Workspace context. Think of model-switching as getting a second opinion from a different coworker without having to re-explain the whole situation.

To switch models mid-chat in Brain:

  1. Using any AI model, begin a chat with Brain. 
  2. After Brain responds, select a different model and continue the chat seamlessly. For example, say you're building a project plan. 
    • You ask Max to pull all the context from your Workspace, such as related tasks, past decisions, and team capacity. 
    • Then, mid-conversation, you switch to Claude to structure the plan, identify risks, and write the narrative brief. 

Select an AI model from a Super Agent

Max is the default model. We also offer other premium AI models. 

To select an AI model from a Super Agent:

  1. Create a Super Agent or open a Super Agent's profile.
  2. Under the Run button, click the Brain icon.

  3. Select one of the available models. 
    • While testing your Super Agent, you can select different models. Think of model-switching as getting a second opinion from a different coworker without having to re-explain the whole situation.

Retry a Super Agent reply using a different model

To retry your Super Agent's response using a different AI model:

  1. Open the Super Agent's reply thread
  2. At the bottom of the thread, click the Retry icon.
