Same prompt in ChatGPT Images 2.5 and Nano Banana 2.1: a station platform scene

The same prompt of a character waiting on a platform at Enoshima station is run through both models; the author finds GPT Images 2.5 far better and Nano Banana 2.1 fast but rough.

图一是ChatGPT Images 2.5生成的Gemini酱在江之岛站台等车的画面图二是新出的Nano Banana 2.1模型用相同提示词生成画面差距还是好大但是速度很快只能说是又快又快了跟Flash一个德行😆 值得注意的地方是Nano Banana 2.1模型仍然属于Gemini 3 系列是基于Gemini 3.6 Flash 研发的为什么不是3.8 flash？很奇怪 Gemini 4代的生图模型目前还没发出也许模型编号会是Nano Banana 2.5 Pro? GPT Image生图功能目前来看还没有哪家公司的大模型可以超越能超越 Images 2.5的只有自己了
