Which should you choose?
Which is better: Motif 3 or Seed Character?
Seed Character is the better all-round choice, scoring 75/100 against Motif 3 (44). It leads on price and inputs & features. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Motif 3 or Seed Character?
Seed Character is cheaper at $0.119 input / $0.297 output per million tokens (official Volcengine Ark API price). Motif 3 costs $0.50 input / $2.00 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.163 per million tokens for Seed Character versus $0.875 for Motif 3 (5.4× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers both models yet. Motif 3 has not been scored yet and Seed Character has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Motif 3 and Seed Character yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Both support tool calling for agent workflows.
Which has the bigger context window?
Motif 3 has the largest context window at 262,144 tokens, against 256,000 for Seed Character. Maximum output per response: Motif 3 up to 262,144, Seed Character up to 256,000 tokens.
Which can read images, PDFs, audio or video?
Motif 3 accepts text; Seed Character accepts text, images and video. Seed Character handles the widest range of inputs.
Are any of these open source?
Motif 3 publishes its weights (MIT) and can be self-hosted; Seed Character is proprietary.
Which is newer?
Motif 3 is the newest, released Aug 7, 2026. Seed Character came out Jun 23, 2026.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
