Two photoreal models that disagree about what photoreal means. One is clinical and obedient. The other is warm and interpretive. The brief, not the quality, decides this one.
Choose GPT Image 2 when the image is commercial and the brief is literal: products, interiors, food, exact counts and placements, output that has to need no clean-up. Choose Seedream 5.0 when the image is lifestyle and the light has to feel real rather than correct, and when you want to spend fewer credits doing it.
Both of these models are good at photorealism and that is where the similarity ends. GPT Image 2, OpenAI's image model, produces the cleanest commercial output on the platform and follows instructions more literally than anything else here. Seedream 5.0, ByteDance's model, produces warmer and less clinical photorealism and interprets more freely.
There are also two hard constraints that settle a lot of briefs before taste gets a say: Seedream as we serve it cannot take a reference image at all, and GPT Image 2 runs the strictest content filtering here. Check your brief against both of those before you spend anything.

Read more about each model: GPT Image and Seedream.
GPT Image 2's output tends to arrive finished. Even lighting, sane composition, usable for a listing or an ad without rework. Products, interiors and food look believable rather than rendered, and the house look is conservative in a way that is exactly right for commerce and exactly wrong for anything that needs to feel candid.
Seedream reads warmer. Skin, hair, fabric and daylight land convincingly and less clinically, and it handles full-body figures and groups in an environment better than most models at its price. If the picture is meant to look like someone took it rather than like someone art-directed it, that difference is the whole job.
Neither is more realistic than the other in any measurable sense. They are realistic in different registers, and the register is a brief decision, not a quality one.
Three items on a shelf. The label facing the camera. Shot from slightly below. GPT Image 2 follows counts, placement and framing more reliably than the other models here, and Seedream is looser on exactly those things. If your brief reads like a spec, every re-roll you avoid pays for the credit difference.
This is also why GPT Image 2 is the default on the product and commercial tools on this platform. The AI Product Image Generator, the virtual staging tools and the listing tools all need a model that does what it is told, because the thing being photographed is a real object whose proportions are not negotiable.
Seedream cannot take a reference image here. It is text to image only on this platform: no reference image, no image-to-image editing. If you have a product photo, a face or a style reference to work from, Seedream is not an option regardless of how its light looks, and GPT Image 2's image-to-image restaging keeps a real product recognisable while changing its surroundings.
GPT Image 2 refuses more. Its content filtering is the strictest on the platform, and prompts involving real people, recognisable brands or edgy themes get declined more often than on any other model here. Refusals refund automatically so a decline costs you no credits, but if your subject sits near that line Seedream will usually just produce the image.
Neither model is the one for words inside a picture. GPT Image 2 is passable for a single short string and Seedream's in-image text is unreliable. For headlines, Nano Banana Pro is the model.
Seedream sits at the cheapest credit tier on the platform and GPT Image 2 above it, so exploration is cheaper on Seedream and finishing is better on GPT Image 2 when the brief is commercial. That is only a useful pattern when the prompt carries across, and across model families it carries less cleanly than it does between tiers of the same family, so expect a different picture rather than the same picture rendered better.
For a commercial brief, the cheaper route is usually to go straight to GPT Image 2 and write a more specific prompt, because its obedience means fewer attempts. For a lifestyle brief, Seedream's price makes a wider exploration affordable, and the warmth is what you came for anyway.
GPT Image 2, clearly. It follows literal instructions about counts, placement and framing more reliably, its output arrives commercially finished without rework, and it can take your real product photo as an input and restage it while keeping the product recognisable. Seedream cannot take a reference image on this platform at all, which rules it out of most product work.
Seedream. It sits at the cheapest credit tier on the platform and GPT Image 2 costs more per image. The exact credit figures and the dollar range across credit packs are in the table on this page, computed from the live pricing registry. For commercial briefs the cheaper model is not always the cheaper outcome, because GPT Image 2's obedience means fewer re-rolls.
It runs the strictest content filtering of any model on the platform, and prompts involving real people, recognisable brands or edgy themes are declined more often than on the other models. Refused generations refund your credits automatically. If your subject sits near that line, Seedream, Nano Banana or Grok Imagine will usually produce the image instead.
No. Seedream is served as text to image only here, with no reference image and no image-to-image editing. GPT Image 2 takes up to four reference images and does image-to-image restaging, so any brief that starts from an upload goes to GPT Image 2, Nano Banana or Nano Banana Pro.
They are photoreal in different directions. GPT Image 2 is cleaner and more clinical, which suits commerce. Seedream is warmer and less clinical, which suits lifestyle. Since the registers differ rather than the quality, the useful test is your own prompt on your own subject, which the Model Comparison tool runs through both in one pass.
