How to prompt ChatGPT (Sol and Astra) for brainstorm architecture sessions like Claude?

A user on reddit.com's dev_community is seeking advice on how to prompt ChatGPT models, specifically Sol and Astra, to facilitate more in-depth brainstorm architecture sessions. The user notes that while Claude provides extensive discussions, Sol and Astra tend to offer bullet-point lists and quickly move to MVP criteria, even when instructed to challenge ideas. They are looking for tips to make Sol and Astra behave more like a peer that challenges them, rather than just listing points.
