ByteDance's new image model is built to handle 100 edits on a single image

Many people know the problem from AI images: You ask for a small fix, and other parts of the image change too. ByteDance, the company behind TikTok, wants to put an end to that with its new image model, Seedream 5.5, which launched on November 9, 2026.

Fix after fix

According to ByteDance, the model can edit a single image for up to 100 rounds in a row. The company says areas that should not change are preserved pixel-identical and without color shifts. A pixel is a single dot in the image.

ByteDance Seed's own product page describes it as targeted changes across multiple edits, with perspective and lighting kept consistent. The examples include changing furniture, hairstyles and props. According to ByteDance, this means you can fix a little at a time without the rest of the image changing.

Transparent background and small text

The model can also create images with a fully or partially transparent background. This makes it possible to reuse stickers and character designs, for example, as design elements without manual post-processing.

Seed also claims that lighting, materials and skin texture are rendered more naturally, and that small text in images is more accurate than before. In ByteDance's own test, critical text errors appeared in 0.4 percent of the test images.

Its own comparisons

ByteDance claims the model is ahead of OpenAI's GPT Image 2.5 and Google's Nano Banana 2.1 on text structure and realism. These are the company's own benchmarks, meaning its own measurements, and they have not been independently verified.

Gradual rollout

The model is being rolled out gradually via ByteDance's services Jimeng, Doubao and Doubao Work, as well as the cloud platform Volcengine Ark. The launch is primarily in ByteDance's Chinese apps, and the sources do not say when or at what price the model will become available globally. A Pro version is planned, but no date has been given.

The model is reportedly set to comply with a copyright agreement that ByteDance entered into with Hollywood studios in August 2026, similar to the one that applies to the Seedance video model.
