In builder chat you can ask another model for a Second opinion without switching the conversation’s host model or starting a separate chat.Open Second opinion near the composer, pick a guest model, and optionally add a focus prompt (for example “find holes in this plan”). The guest sees a cleaned-up view of the thread (including condensed earlier tool results) and may read your app’s data models to verify claims. It cannot create, update, or delete records, and it cannot change the app.The guest’s reply appears as its own attributed message. The host agent does not continue until you ask it to (for example with Ask agent to respond).Availability notes: Second opinion appears near the composer after the host agent has sent at least one reply (not on a brand-new empty chat). It is available in builder chat (full page and the page side panel). It is not offered in the end-user portal yet.
