Model comparisons
Kling O3 or MiniMax H3 Edit, tier by tier: matched prices, request fields, limits and the content policy measured on each.
Kling O3 (Kling 3.0 Omni) video editing takes a video you already have and changes only what your prompt names. Source clips run 3 to 10 seconds at 720p or 1080p, with up to 4 optional reference photos for a new character or object.
View model details →View sample outputs →MiniMax H3 video edit rewrites the weather, light, style or setting of a clip you send, while your footage keeps driving who is in it, the composition and the motion. Edits run 3 to 15 seconds at 480p, 540p or 768p, with new sound by default.

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.
Kling O3: 720p $0.125 / output seconds · 1080p $0.168 / output seconds
MiniMax H3 Edit: 480p $0.03 / output seconds · 540p $0.045 / output seconds · 768p $0.066 / output seconds
About this comparison
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?
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.
Kling O3
This model refuses requests beyond its own limits outright. Measured, not assumed — models we have not measured carry no label at all.
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?
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.
How to choose
MiniMax H3 Edit supports clips up to 15 seconds.
Kling O3 supports a high-resolution option.
Compare
The model identifiers are kling/o3/video-edit and minimax/h3-edit/video-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.
Questions developers ask
The two bill on different tiers, so there is no like-for-like row: Kling O3 starts at $0.125 / output seconds and MiniMax H3 Edit at $0.03 / output seconds. Prices may change; check the estimate shown for your actual settings before submitting.
Kling O3 allows 60 minutes per task and MiniMax H3 Edit allows 60. Those are ceilings rather than typical times — most requests finish far sooner — but they are what your own client timeout has to survive.
