Generate a video on Seedance 2.5 or open the API documentation to run Seedance 2.5 on this site first. The notes below then explain the Kie channel without sending you off-site: create a Kie API key, call the Seedance 2.5 job endpoint (create task, then poll status), set duration and resolution (480p / 720p / 1080p), and estimate spend from the per-second price card on the Kie Seedance 2.5 page. Rates differ for requests with vs without reference video—copy the card, do not invent a blended dollar figure.

This guide covers Kie setup, the verified credit and dollar table, billing formulas, and how to place Kie beside fal, Replicate, and WaveSpeed. For credential basics across providers, see the Seedance API key guide. For our own credit-billed integration, use the API documentation and models and pricing.
How do you set up Seedance 2.5 on Kie?
- Create a Kie account and an API key; store it on your backend only.
- Open the Kie market docs for the Bytedance Seedance 2.5 model and confirm the live
createTaskschema there before you ship. This page does not link out to those docs. - Choose resolution (480p, 720p, or 1080p) and duration (Kie product framing: about 4–30 seconds).
- Decide whether the job includes reference video. That choice switches which per-second column you use and whether uploaded video duration is billed.
POSTa task, then poll the unified query endpoint until the result URL is ready.- Estimate cost from the price card before production batches; the card labels rates as beta.
Illustrative flow (confirm field names on the live docs before production):
export KIE_API_KEY="your_kie_api_key"
curl --request POST \
--url https://api.kie.ai/api/v1/jobs/createTask \
--header "Authorization: Bearer $KIE_API_KEY" \
--header "Content-Type: application/json" \
--data '{"model":"bytedance/seedance-2-5","input":{"prompt":"A ceramic cup on a wooden table. Soft steam rises as the camera slowly pushes in.","resolution":"720p","duration":5}}'
Adapt model / input keys from the current OpenAPI page. Treat the job as asynchronous: create, then poll, then download.
Verified Kie price card (2026-10-25)
Copied from the Kie Seedance 2.5 price card (the same figures are explained on the Kie pricing article). One credit ≈ $0.005 at the listed conversion (1 USD = 200 credits).
| Resolution | Without video input | With video input |
|---|---|---|
| 480p | 28 credits/s ($0.140/s) | 17 credits/s ($0.085/s) |
| 720p | 63 credits/s ($0.315/s) | 38 credits/s ($0.190/s) |
| 1080p | 158 credits/s ($0.790/s) | 95 credits/s ($0.475/s) |
Billing formulas stated on the same card:
| Mode | Formula |
|---|---|
| Without video input (text / images / audio refs only) | Rate × generated duration |
| With video input (one or more reference videos) | Rate × (uploaded video duration + generated duration) |
Additional verified notes:
- Reference images and reference audio add no billable seconds (Kie market docs).
- Prices are labeled beta and may be adjusted—re-check the card before locking a client quote.
- High-tier top-ups may include a +10% credit bonus (effective per-credit cost can be lower than the $0.005 list conversion).
- Draft mode: 480p preview; draft task ID valid 7 days; upgrade via the Seedance 2.5 Draft path at the standard table, inheriting with-video / no-video mode.
Worked examples (arithmetic on the card only)
| Job | Calculation | Credits | USD @ $0.005/cr |
|---|---|---|---|
| 10 s · 720p · text only | 63 × 10 | 630 | $3.15 |
| 15 s · 1080p · first frame (no video) | 158 × 15 | 2,370 | $11.85 |
| 15 s · 720p · guided by 10 s reference video | 38 × (10 + 15) | 950 | $4.75 |
Resolutions: Kie page vs Seedance 2.5 model caps
The Kie Seedance 2.5 card lists 480p / 720p / 1080p only. That matches our product hard rule for Seedance 2.5: no 4K tier.
| Source | What it lists for Seedance 2.5 |
|---|---|
| Kie Seedance 2.5 price card (2026-10-25) | 480p · 720p · 1080p (no 4K row) |
| Model / our product writing | 480p · 720p · 1080p; 4K belongs to Seedance 2.0 contexts |
| If another platform page shows 4K near “Seedance 2.5” | Label platform page wording vs model official 2.5 caps and verify the live enum |
Do not invent a Seedance 2.5 4K price from a 2.0 comparison row.
How does Kie compare with fal, Replicate, and WaveSpeed?
Keep each provider’s auth, schema, and bill separate. Use sibling guides for their verified numbers—do not paste Replicate per-second dollars into a Kie estimate.
| Provider guide | Shape to remember |
|---|---|
| fal API | fal-specific model routes and billing |
| Replicate API | bytedance/seedance-2.5 with that article’s verified per-second rates |
| WaveSpeed API | Endpoint starting-price table + separate FAQ per-5s rates; edit/extend routes |
| This Kie guide | Credit/s table with with-video vs no-video columns |
| API providers comparison | Side-by-side decision frame |
| Models and pricing (our API) | Credit-billed catalog on this site |
For a first creative check outside API billing, generate on Seedance 2.5. The web experience offers free credits on sign-up, enough for one video—separate from Kie account credits (the Kie new-user credit grant is a platform figure; do not treat it as our product CTA).
FAQ
What is the cheapest verified Kie rate for Seedance 2.5?
On the 2026-10-25 price card, the lowest listed per-second row is 480p with video input at 17 credits/s ($0.085/s)—but uploaded video duration is billed too. For text-only jobs, the lowest row is 480p without video at 28 credits/s ($0.140/s).
Why is the with-video rate lower?
Because both input and output durations are billed. The card states: rate × (total uploaded video duration + generated duration).
Does Kie list a 4K Seedance 2.5 price?
No. The Seedance 2.5 card verified on 2026-10-25 lists 480p / 720p / 1080p only. Treat any 4K claim as platform-vs-model conflict unless a live Seedance 2.5 enum clearly exposes it.
Are Kie prices the same as credit prices on this site?
No. Kie bills its own credits and dollar table. Our models and pricing page describes the credit-billed API on this site. Compare auth and units separately.
Do reference images or audio add billable seconds on Kie?
Per the Kie market docs (as cited on the Kie pricing explain page): no. Only reference videos add billable time under the with-video formula.
