## Direct answer

Seedream 4.0 is ByteDance's image generation and editing model. On GPT Image Hub it costs 25 credits per image at any size, 1K, 2K or 4K, which makes its 4K output one of the cheapest on the site. In the Hub's tests 1K and 2K images took about 20 seconds and a 4K landscape took 137 seconds. Choose it for photographic scenes and large exports on a budget; choose Seedream 4.5 or 5.0 for stronger text and design work.
