Facts verified2026-09-07

Seedance 2.0 is ByteDance's video model, launched February 12, 2026. It holds photoreal motion and multi-subject camera moves for a full 4 to 15 seconds, and it writes native audio in the same pass as the picture. You can lock a face, a product, and a camera move with up to nine stills and three clips, then describe how they combine. That is why it shows up in character-locked product films. On Elyum the four routes are text to video, image to video, reference to video, and video editing. Details live on the Seedance 2.0 page.

The model is the same. The bill is not. WaveSpeed AI is a pay-per-use inference aggregator with no subscription tiers. WaveSpeed's model catalog lists Seedance 2.0 and a 2.0 Mini variant, but WaveSpeed AI does not publish a Seedance 2.0 dollar price. Failed requests, system errors, and timeouts get an automatic refund within about 3 hours. Elyum prices Seedance 2.0 in credits (1 credit = $0.01) on Elyum pricing, charges only when you keep a take, and never charges a failed generation. The Free plan is up to 150 credits once (our algorithm may grant them), no card.

WaveSpeed AI is stronger if you need breadth and plumbing: 1,000+ models, one API key, and a published ComfyUI node pack. Elyum is a studio, not an aggregator. It has no timeline editor, no stock footage, no avatars, no mobile app, no team seats, and no community feed. Trustpilot showed 2.6/5 from 4 reviews as of 2026-09-07, a small sample. If you already route many models through one key, WaveSpeed AI is the more honest match. For the newer cut, see WaveSpeed AI vs Elyum for Seedance 2.5.

Seedance 2.0 on WaveSpeed AI

WaveSpeed AI does not sell Seedance 2.0 on a plan. There are no subscription tiers. You top up and pay per generation. Bronze, Silver, Gold, and Ultra account tiers raise rate limits with cumulative spend. The catalog lists Seedance 2.0 and a 2.0 Mini variant. A Seedance 2.0 unit price is not published. WaveSpeed AI does publish Seedance 2.5 examples (about $0.81 to $0.90 for 480p, 5s), which is a different SKU. New accounts get $1 in one-time trial credits, no card. Some premium or partner models may be excluded from that grant.

A failed request, system error, or timeout is refunded automatically within about 3 hours, per WaveSpeedAI's refund-policy page. Client-side timeouts in Sync Mode are not auto-refunded if the job finished on the server; retrieve it by prediction ID. There is no keep/kill meter. A finished take you dislike is still a billed generation. Credits do not expire. Watermark behavior on paid Seedance 2.0 files is not published. Company-level notes live on the WaveSpeed AI alternative.

Seedance 2.0 on Elyum

Where the two differ

Billing unit

WaveSpeed AI charges per completed generation (pay-as-you-go, no subscription). Elyum charges per second of a kept take only. Previews are free. A 5s 480p keep is 30 credits ($0.30).

Bad takes and refunds

WaveSpeedAI's refund-policy page grants an automatic refund within about 3 hours for failed requests, system errors, and timeouts. A completed take you dislike still bills. On Elyum, kill a preview for a full refund (one kill a month on Free; unlimited on paid). Failures never bill.

Resolution and duration

Elyum runs Seedance 2.0 at 480p, 720p, and 1080p for 4 to 15 seconds. WaveSpeed AI's published 480p/720p/1080p and 30s figures are for Seedance 2.5, not 2.0. A Seedance 2.0 cap on WaveSpeed AI is not published.

API and workflow

WaveSpeed AI is API-first (one key across 1,000+ models), plus a web playground and the WaveSpeedAI/wavespeed-comfyui node pack. Elyum is a web studio plus MCP and a REST API. Elyum has no timeline editor and no ComfyUI pack.

Credits, plans, and top-ups

WaveSpeed AI has no plans. Manual top-ups (reviewers mention roughly $100 / $1k / $10k) and optional auto-topup. One Trustpilot review said auto-topup charged two $55 amounts against a $15 setting. Credits never expire. Elyum: Free, Plus $9/mo, Pro $29/mo, Ultra $69/mo, plus top-ups. 1 credit = $0.01.

Catalog around this model

Getting the most out of Seedance 2.0

Name the camera move in the prompt (dolly in, orbit, handheld push). Seedance 2.0 holds multi-subject action and camera for a full 4 to 15 seconds. Vague motion words do not lock a path.
Use reference stills to lock the face, wardrobe, and product. You can attach up to nine images and three clips in one generate. Keep those refs visually consistent or the lock slips.
Write the audio in the same prompt. Speech, room tone, and effects generate with the picture, not as a second pass. Put quoted dialogue and the room (studio, street, showroom) in the same sentence.
Stay inside 4 to 15 seconds on Elyum. Ask for one beat per take. A 15s clip that tries to cover three locations usually smears the last third.
For product films, lock the SKU with a still and describe how the camera treats it. Reference-to-video is the usual path when the object has to match across takes.
Pick an aspect ratio and keep it. Elyum offers four. If you have an existing clip, use the video editing route and feed the clip plus stills rather than restating the whole scene.
