Fourteen platforms. One model. Ten "API" listings — but only one is a disclosed enterprise partner, three are degraded to 720p, two are suspicious, and one explicitly admits it's not affiliated with ByteDance at all. This is the colorist's report on what's actually on the other end of your API key.
The audit changed everything. ByteDance suspended the overseas API on 15 March 2026 after Disney, Warner, Paramount and Netflix sent cease-and-desists. Most "Seedance 2.0" providers are operating in legal grey area, routing via Volcengine through Chinese intermediaries. The cheapness gradient hides huge differences in what you actually receive.
Atlas Cloud's "1080p" is fake — it's a FlashVSR upscale on top of native 720p output. PiAPI explicitly says "Non-official, not affiliated with ByteDance" on their own page and doesn't generate audio natively. fal, Replicate and Segmind all cap at 720p — meaningful divergence from the official 1080p Std tier.
Sorted ascending. All rates are per generated second of 720p video on the model's Fast tier — the apples-to-apples baseline. Where a provider only publishes a per-clip price, we've divided by clip length.
The colored ribbon at the top of each card is the authenticity verdict, established by a deep audit of each provider's own pages, schemas, press releases and disclaimers. The resolution chip next to the name tells you whether it's true 1080p, capped at 720p, or — in one case — fake-1080p-via-upscaler. Native-audio output (a Seedance 2.0-only capability) is flagged green ✓ or red ✗.
Move the dials. The cheapest provider for your usage rises to the top, and you'll see the exact moment Runway's flat $76 plan beats pay-as-you-go.
Three dials. The math runs live.
clips × seconds × $/sec — failed gens not counted
Most providers gate higher resolutions behind their Standard tier. Here's the cheapest published rate for each resolution across all providers offering it.
UI-only platforms — no programmatic API. Runway is the second confirmed official partner (after fal); the others vary. Higgsfield's credit math works out to 5× the BytePlus list rate on its best plan, but it inherited ByteDance's US/JP geo-block — a strong signal it's running the real model. CapCut and Dreamina are ByteDance's own products.
