WaveSpeed AI vs Elyumfor Seedance 2.5
WaveSpeed AI bills every Seedance 2.5 run. Elyum charges only the takes you keep, from $0.40 for 5s at 480p.
Seedance 2.5 holds a 4 to 30 second photoreal take in one pass, with native audio (ambience, foley, speech, and lip sync) generated with the picture. ByteDance released it on July 31, 2026, after Seedance 2.0's 15-second native ceiling. The look is live-action: textures, skin, lighting, and camera that hold for a full clip. On Elyum you can lock faces, products, locations, and style with up to 30 references, and you can edit an existing clip instead of regenerating the whole take. Routes are text to video, image to video, reference to video, and video editing.
The model is the same. The bill is not. WaveSpeed AI prices Seedance 2.5 per run. WaveSpeed's Seedance 2.5 API page lists text-to-video, image-to-video, video-edit and video-extend, about $0.81 to $0.90 for 5s at 480p and about $1.80 for 5s at 720p. Elyum bills in credits (1 credit = $0.01) and charges only when you keep a take. Failed generations are never charged on Elyum. WaveSpeed AI auto-refunds failed requests, errors, and timeouts within about three hours; Sync Mode client timeouts are not auto-refunded if the job finished server-side. WaveSpeed AI has no subscription. Elyum plans sit on the pricing page; Seedance 2.5 runs on Free if you have credits.
WaveSpeed AI still wins if you live in ComfyUI or you need one key across 1,000+ models. Elyum is a studio, not an aggregator. Elyum does not have a timeline editor, stock footage, avatars, a mobile app, team seats, or a community feed. If you already compared WaveSpeed AI vs Elyum for Seedance 2.0, the split is the same, just a longer clip. For the rest of the catalog, see the WaveSpeed alternative page.
Seedance 2.5 on WaveSpeed AI
Seedance 2.5 is live on WaveSpeed AI with no monthly plan. WaveSpeed AI is pay-as-you-go: a one-time $1 trial (no card to start; some partner models may be excluded), then manual top-ups. WaveSpeed's Seedance 2.5 API page lists text-to-video, image-to-video, video-edit and video-extend, clips up to 30 seconds, and 480p, 720p, and 1080p, priced per run and per second. Published examples: about $0.81 to $0.90 for a 5s 480p text or image-to-video run, and about $1.80 for 5s at 720p. A 1080p Seedance 2.5 unit price is not in the fetched examples.
A failed request, system error, or timeout is auto-refunded within about three hours, per WaveSpeed's refund policy. Client-side timeouts in Sync Mode are not auto-refunded if the job completed server-side; retrieve it by prediction ID. A completed but unusable take is still a paid run. One Trustpilot reviewer wrote that about half of a batch of 20 purchased generations came back unusable or un-generated, and that support did not respond to email. WaveSpeed AI does not publish a keep-or-kill preview. Paid-file watermark is not published.
Seedance 2.5 on Elyum
On Elyum, the Seedance 2.5 page lists 480p at 8 credits/second (5s = 40 credits = $0.40; 15s = 120 credits = $1.20), 720p at 19 credits/second (5s = 95 credits = $0.95; 15s = 285 credits = $2.85), and 1080p at 26 credits/second (5s = 130 credits = $1.30; 15s = 390 credits = $3.90). Clips are 4 to 30 seconds with native audio. Routes: text to video, image to video, reference to video, and video editing. 1 credit = $0.01.
Every render comes back as a free preview. You judge it, then keep the takes you want (that is the only moment credits are charged) or kill the rest for a full refund. A failed generation is never charged. Kills are metered on Free (one kill a month); paid plans kill freely. Kept downloads are clean, full quality, no watermark, commercial use included. Free is up to 150 credits once (our algorithm may grant them), no card. Plus is $9/mo, Pro $29/mo, Ultra $69/mo; you can also top up. You can run the same model from the web studio or from Claude, ChatGPT, and Cursor via the MCP docs and the REST API docs.

Where the two differ
WaveSpeed AI charges per Seedance 2.5 run and per second. Elyum charges credits only when you keep a take: 8, 19.2, or 26 credits per second at 480p, 720p, or 1080p (1 credit = $0.01).
WaveSpeed AI auto-refunds failed requests, system errors, and timeouts within about three hours. Sync Mode client timeouts are not auto-refunded if the job finished server-side. Elyum never charges a failed generation. Killing a preview refunds in full (one kill per month on Free).
Both list Seedance 2.5 up to 30 seconds in one shot at 480p, 720p, and 1080p. WaveSpeed AI also lists video-extend. Elyum lists reference to video (up to 30 refs) as a first-class route beside text, image, and edit. WaveSpeed AI's fetched Seedance 2.5 note does not list reference-to-video.
WaveSpeed AI is API-first: one key, a web playground, and a ComfyUI node pack. Elyum is a web studio plus MCP and a REST API. Elyum has no timeline editor, stock footage, avatars, mobile app, team seats, or community feed.
WaveSpeed AI has no subscription tiers. Its refund-policy page says the balance never expires. Bronze, Silver, Gold, and Ultra raise rate limits with top-up spend. Elyum sells Free, Plus $9, Pro $29, and Ultra $69, plus top-ups. Pro and Ultra unlimited images do not apply to Seedance 2.5.
Elyum includes commercial use on kept, watermark-free downloads. WaveSpeed AI links a Commercial Use Policy from its refund-policy doc; specific terms were not in the fetched excerpt. Paid-file watermark on WaveSpeed AI is not published.

Seedance 2.5 in three styles, rendered on Elyum
Getting the most out of Seedance 2.5
- Write the shot as one continuous take. Seedance 2.5 generates 4 to 30 seconds in one pass. Name the camera move (locked off, slow dolly in, handheld follow) and the subject move as two separate clauses so they do not fight.
- If there is speech, put the line in quotes and name the speaker. Native audio generates with the picture. Specify room tone and one or two foley cues (cloth, footsteps, a door) instead of a long sound list.
- When you attach references, label them in the prompt: ref 1 is the face, ref 2 is the product, ref 3 is the location. Seedance 2.5 accepts up to 30 refs on Elyum. More refs lock identity; they do not replace a clear action line.
- For a 30s ad, write three beats with clocks (0-8 product hero, 8-20 use, 20-30 pack shot). A 5s prompt that asks for five scene changes will smear.
- For edits, say what must stay and what must change. Swap the product, keep the actor and camera. Do not ask for a new story and a surgical patch in the same prompt.
- Skip quality adjective stacks. Specify lens feel (35mm wide, 85mm close-up), time of day, and the lighting source. Photoreal is the default look; extra praise words do not buy sharpness.
