ByteDance claims that Seedream 4.0 beat Gemini 2.5 Flash Image for image generation and editing on its internal evaluation benchmark
TikTok-owner ByteDance has launched its latest image generation artificial intelligence tool Seedream 4.0, which it said surpasses Google DeepMind’s viral “Nano Banana” AI image editor across several key indicators.
ByteDance’s Seed department, which oversees the tech unicorn’s AI development efforts, said on Tuesday that Seedream 4.0 had strong image editing capabilities, putting it in direct competition with Nano Banana, officially known as Gemini 2.5 Flash Image.
The US model has received wide acclaim since its release in late August for the consistency and accuracy of its image editing abilities, which have been a challenge for AI image generators until now.
