The Hub lets you query multiple LLMs simultaneously:

1. Choose 1, 2, or 3 panes using the panel selector in the top-right
2. Select which LLM to use in each pane (Claude, Gemini, or ChatGPT)
3. Paste your prompt into each pane and compare responses

This is useful when you want an "LLM council" — get multiple perspectives on a question and see where the models agree or differ.
