Ethan Mollick 实测 Gemini 4：整体大幅跃升，复杂多智能体任务仍落后

Ethan Mollick 在 Gemini 4 发布前花了不少时间试用，认为它相比前代 Gemini 是大幅跃升，也是首个跨过 Fable/Mythos/Astra 门槛的非 OpenAI、非 Anthropic 模型，个性与品味明显区别于 Claude 或 Astra。在创意写作等方面它至少与 OpenAI、Anthropic 持平，但在复杂多智能体任务上落后，且倾向于对结论过于笃定、略显偷懒，Antigravity 工具链也不如竞品。他仍预计以 Gemini 4 为基础会带来模型能力的快速提升。

I spent a decent amount of time with Gemini 4 before launch. Overall, Gemini 4 is a big jump over previous Gemini models and it is the first non-OpenAI/Anthropic model to pass the Fable/Mythos/Astra bar. It is also much more pleasant and more agentic then previous Gemini models, without the weird personality issues that you often found in Gemini 3 series models. In fact, a big advantage is that has a very different personality and sense of taste than Claude or Astra, making it a good addition to the AI world.
On the usefulness side, in some areas it is at least at par with OpenAI and Anthropic (it is quite creative and a good writer), but in others it lags, including at complex multi-agent work. It has a tendency to be too certain about its conclusions and a little lazy, issues not helped by the Antigravity harness not being quite as good as the competition. Still, I expect to see rapid improvements in model abilities using Gemini 4 as a base.
Here is a fun example: "create the ultimate brutalist city builder. you should have lots of controls over buildings in ways that are delightful and inuitive to people who just want to play, but are sophisticated and deep for people who know something about architecture. you should be able to play a lot with design and approach. there should be simulation modes and different ways to view or experience the city. make it stunning. i want to host this on netlify in the end"
