Select an AI model from Brain
Max is Brain's default model. We also offer other standard and premium AI models.
To select an AI model from Brain:
- Open Brain.
- In the lower-right corner, click the Brain icon.
-
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:
- Using any AI model, begin a chat with Brain.
- 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:
- Create a Super Agent or open a Super Agent's profile.
- Under the Run button, click the Brain icon.
- 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:
- Open the Super Agent's reply thread.
- At the bottom of the thread, click the Retry icon.
