The short answer
Start with the input you have, the result you want and your budget. These are the differences that affect that choice.
- FLUX 3 is listed as Filtered; Wan 3.0 as Uncensored. Compare the examples and content-test details on each model page for the scenes you want to create.
- The two bill on different tiers, so there is no like-for-like row: FLUX 3 starts at $0.06 / output seconds and Wan 3.0 at $0.045 / output seconds.
- Wan 3.0 runs to 30 seconds in one request; FLUX 3 stops at 20, so anything longer has to be stitched together.
Compare the published examples, then try the same input on both models with matching settings.

Current price
Price at the same setting
A start price answers a different question than the one you have. These are the tiers both models publish, matched setting for setting, in US dollars per billed unit with no conversion step in between.
These two bill on different tiers, so there is no row to line up. Each one's own published tiers are listed here instead.
FLUX 3: Output quality: Draft · 1080p $0.06 / output seconds · Output quality: Draft · 720p $0.06 / output seconds · Output quality: Standard · 720p $0.17 / output seconds · Output quality: Standard · 1080p $0.29 / output seconds
Wan 3.0: 480p $0.045 / output seconds · 720p $0.09 / output seconds · 1080p $0.18 / output seconds
What one ordinary job costs
- FLUX 3: $0.85 for a five-second clip at Output quality: Standard · 720p.
- Wan 3.0: $0.45 for a five-second clip at 720p.

Every row here is read from the JSON Schema the endpoint validates against, so it matches what the API will really accept rather than a feature list written by hand.

Do low-filter models allow every request?
Content policy, side by side
Two separate facts sit behind these labels. The first is what we do, which is nothing: no platform content filter, and no maturity flag to set on a request. The second is what each model does on its own, and that is the only part that varies between these two.
FLUX 3
Filtered
This model refuses requests beyond its own limits outright. Measured, not assumed — models we have not measured carry no label at all.
Wan 3.0
Uncensored
This model declares no content filter. SpicyAPI forwards the request without adding a platform content scan; legal and consent duties remain with the customer.
Usage note Use only authorised, general-audience-safe material. Do not create sexual content involving minors, non-consensual intimate imagery, or deceptive impersonation of a real person.
Use these content labels to shortlist models, then open each model page for available examples and content-test details.
The label never changes your obligations. Age, consent, real-person likeness and the law where you operate stay with you, and SpicyAPI does not inspect each request.
Can I swap the model ID without changing the request body?
Request body, field by field
The task lifecycle is shared; the body is not. Each endpoint publishes its own JSON Schema and the API validates against that, so this is the list to reconcile before a switch.
- 7 fields appear in both request bodies under the same names. aspect_ratio, duration_seconds, generate_audio, image_url, last_image_url, prompt, resolution
- Only FLUX 3 accepts: quality.
- Only Wan 3.0 accepts: enable_prompt_expansion, enable_thinking, seed.
- FLUX 3 requires image_url, prompt.
- Wan 3.0 requires image_url.
- Both reject unknown fields outright, so a parameter left over from the other model comes back as a validation error instead of being quietly ignored.

Moving from one to the other
The model identifiers are black-forest-labs/flux-3/image-to-video and alibaba/wan-3.0/image-to-video, and both go in the same field of the same request.
Both run the same way: submit the task, then poll it or take the callback. Queueing and retry logic carry over unchanged.
Both use the same submit-and-track flow, but their required inputs may differ. Check each model page before switching.
One key, one balance, one set of spend caps. Both bill to the same account in US dollars, and the per-key daily, monthly and lifetime limits apply to whichever one you call.
Questions developers ask
Which is cheaper, FLUX 3 or Wan 3.0?
Which is cheaper, FLUX 3 or Wan 3.0?
The two bill on different tiers, so there is no like-for-like row: FLUX 3 starts at $0.06 / output seconds and Wan 3.0 at $0.045 / output seconds. Prices may change; check the estimate shown for your actual settings before submitting.
How long can a single request run?
FLUX 3 allows 60 minutes per task and Wan 3.0 allows 180. Those are ceilings rather than typical times — most requests finish far sooner — but they are what your own client timeout has to survive.
