Gemini 4's writing and multi-agent work in a prelaunch assessment

After spending time with Gemini 4 before launch, one tester calls it a big jump over earlier Gemini models and says its personality is more pleasant and distinct from Claude and Astra. They say it is creative and a good writer, but lags at complex multi-agent work, tends to be too certain and can be a little lazy. They also say the Antigravity harness isn't quite as good as the competition.
