The Chinese are so much ahead in this space, their models are way better at this stuff. For example, https://hunyuan.tencent.com/image/en?tabIndex=0 and https://seed.bytedance.com/en/seedream5_0_lite
When it comes to image prompts, Seedream is far behind Nano Banana. "Far behind" is a ridiculous understatement here, btw.
Afaik the only real competitor is Riverflow V2.
which models?
we have user-preference rankings that put NB2 on top: https://arena.ai/leaderboard/text-to-image
