Seedream 4.5
The unfiltered Seedream
Seedream 4.5 is ByteDance’s earlier image model, available on Ochra for text-to-image and for image editing. It renders the family’s cinematic colour without the content filter that Seedream 5 applies, which is the main reason it is still kept in the catalogue today.

What is different about Seedream 4.5
- Superseded by Seedream 5 on quality, and kept because it is not content-filtered.
- Faster and cheaper than the current line, which makes it usable for volume drafting.
Strengths and limits
Key Features
- Not content-filtered, so it runs work Seedream 5 refuses.
- Cheap enough to draft with at volume.
Where it falls down
- Seedream 5 renders better. Choose 4.5 for the filter difference or the price, not the finish.
Seedream 4.5 questions
Use 5 for the better render. Use 4.5 when the content filter on 5 refuses the work, or when you are drafting at volume and the price difference matters more than the finish.
