> see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt

Really? I start with a conversation for maybe 5 turns or so, where I ask it what would need to change, what the API might be, any database schema changes, URL schemes, and so on, and finally ask it to break it down into commits. Then I let it go, implementing 3-10 commits at a time via subagents. It usually gets the UI somewhat wrong, so there are followups to fix it. This is with Sol and Luna subagents.

Is that what other people see?

Try using Astra, Fable, Opus.
