Our take
Written Sep 2, 2026Seed-2.0-Lite is ByteDance's proprietary multimodal model that handles text, images and video across a 262,144-token request limit. It launched in March 2026 with no published parameter count and no measured quality scores in our data.
Pick this for long-context multimodal workflows that need a quarter-million tokens of working memory, or when you want direct billing through Seed's own API at 83 tokens per second. Skip it if you need verified quality benchmarks, an open licence, or competitive output pricing.
The case for it
- 262,144-token request limit — among the largest for multimodal work with text, images and video.
- Two hosted offers with identical rates, including direct access from Seed.
The case against it
- No benchmark scores in our data — chat, reasoning, coding and multimodal boards are all unmeasured.
- Proprietary weights with no open licence; you cannot download or self-host.
- Output rate is high relative to unverified quality, with no scores to justify the cost.
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.
