Our take
Written Sep 11, 2026Seed-2.0-Code is ByteDance Seed's proprietary coding specialist that accepts text, images and video, with a 262,144-token request limit suited to large codebase review. It is a multimodal bet on long-context code work rather than a measured-quality pick.
Choose this when you need to feed entire codebases, UI screenshots or video walkthroughs into one prompt, and the 262,144-token limit matters more than benchmark proof. Use ByteDance Seed's own endpoint if you want the 21.5 tokens per second it reports. Skip it if you need verified coding scores, self-hosting, or a low output rate without quality evidence.
The case for it
- Among the longest request limits we track for coding-specialist models, at 262,144 tokens.
- Accepts images and video alongside text, so UI screenshots, diagrams or demos can sit next to code in the same prompt.
The case against it
- No benchmark scores in our data — chat, coding, reasoning and multimodal quality are all unverified.
- Proprietary weights with no licence listed and no parameter count disclosed; you cannot self-host or audit.
- Output rate is steep for an unproven model, with no scores to justify it against alternatives.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.

DeepInfraAcross the 3 listings we hold: 1 says it does not train on prompts, 0 say they do and 2 do not say. 1 appears in the zero-retention registry we check; the rest are unknown to us.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- No independent board has scored it, so we hold no quality figures at all.
- 1 of 3 listings publishes no parameter list, so what its API accepts is unknown to us.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 2 of 3 listings do not say whether they train on prompts.
- We don't hold a list price for this model yet — the gap is ours, not the lab's.
- We hold no cached-input rate for any of its listings.
- We hold no batch or off-peak rate for any of its listings.
