| Evidence status | Reported / coming; not an official ByteDance release note yet | Existing speed-oriented Seedance 2.0 lane on current provider surfaces | Reported upgrade with ~20% quality-improvement framing | Older/pro comparison reference; OpenRouter page lists comparison fields |
| Core positioning | Lower-cost Mini tier for high-volume iteration and affordable short-form generation | Fast preview lane optimized for quicker outputs with some detail trade-offs | Premium quality bump candidate for final-output retesting | Prior-generation Pro baseline for comparison context |
| Pricing signal | Reported to land well below Seedance 2.0 Fast on price-per-second | Below Standard, but expected to lose value advantage if Mini claims hold | TBD; likely premium or at least not the low-cost lane | OpenRouter comparison page shows token-style fields, not a direct public video price |
| Best use case | Prompt A/B tests, social clips, education content, internal eval pipelines | Latency-sensitive preview generation where Fast is already exposed | Retesting hardest prompts, premium output, and quality-sensitive workflows | Legacy/pro benchmark when comparing model family progress |
| What to verify | Compare against Fast using your own prompts: text rendering, motion stability, identity consistency, physics-heavy scenes | Check whether speed still matters enough if Mini is cheaper and comparable or better | Verify whether the reported quality lift appears on your failure cases | Confirm provider capability fields before treating it as a video-generation substitute |
