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.

Controls and limits
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.
Qwen Image 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.
Seedream 5.0 Flash
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 Unfiltered content needs no separate switch or endpoint. Do not submit material involving minors, non-consensual intimate imagery, or deceptive impersonation of real people. This statement is a usage boundary, not a claim that every request is automatically screened.
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.
- 4 fields appear in both request bodies under the same names. aspect_ratio, image_urls, prompt, resolution
- Only Qwen Image 3.0 accepts: enable_prompt_expansion, negative_prompt, num_outputs, seed.
- Only Seedream 5.0 Flash accepts: background, output_format.
- Qwen Image 3.0 requires image_urls, prompt.
- Seedream 5.0 Flash requires image_urls, prompt.
- 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.
Compare
Moving from one to the other
The model identifiers are alibaba/qwen-image-3.0/edit and bytedance/seedream-5.0-flash/edit, 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.

How long can a single request run?
