That's a good point and something I encountered yesterday. On a multi-agent task, Gemini was the only model that got near the end, ran tests, saw it had issues, took a screenshot, saw the issues, and then said, "I'll mark it complete" and delivered.
I was paying for Ultra, then downgraded to Pro and at this point I'm near abandoning it. Agy as a harness also has a tendency to constantly request significant elevations to perform routine operations.
