Seedream detector

Was this image made with Seedream? Check it free with Checkobot, see where detection can miss, and find our catch rate here once it's measured.

Checko doesn’t name the generator. It tells you whether an image shows signs of AI. We're measuring how often that catches Seedream images, and will publish the rate here with the date we measured it.

How well we catch Seedream

Measurement pending. We publish a catch rate here only after testing on a fresh set of Seedream images, with the date we measured it.

About Seedream

Seedream is ByteDance's image model. It's available in ByteDance's own creative apps and through API providers, and it both generates new images and edits existing ones.

  • Seedream images often reach other platforms through short-video and social apps, which recompress them. The original file works best.
  • Edits of real photos lean on the face analysis as much as the whole-image analysis.

Where it can miss

  • New versions of Seedream can look different from older ones, and detectors can take time to catch up.
  • Heavy edits, upscaling or filters after the image was made can hide the traces detectors look for.
  • Screenshots and re-shared copies add compression. Very small or heavily compressed images are refused rather than guessed at.

Getting a good check

  • Find the largest, earliest copy of the image you can. A reverse image search often turns it up.
  • Check the original file rather than a screenshot of it.
  • If there’s a face, make sure it’s at least 64 pixels across so the face analysis can run.

Questions

Can Checkobot detect Seedream images?

We're measuring it now. This page will show our catch rate on a fresh set of Seedream images, with the date we measured it.

Will Checko tell me the image was made with Seedream?

No. Checko tells you whether an image shows signs of AI generation or editing, not which tool made it. Once measured, this page will show how often that catches Seedream images.

Is it free?

Yes. You can check 3 images a day without signing up, or 10 a day with a free account.
