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.
DeepSeek V4 Pro
Uncensored
We add no content filter to this model, but like most chat models it declines a blunt request that comes with no context. It writes unrestricted fiction reliably once your system prompt sets up a fiction-writing context, or once the request is framed as a story. Legal and consent duties remain with the customer.
Usage note An NSFW refusal from V4 Pro can reflect the model’s own behaviour even though SpicyAPI adds no content filter to this text endpoint. Use authorized source material with DeepSeek V4 Pro, respect privacy and review the result before relying on it.
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.
- 8 fields appear in both request bodies under the same names. stop, tools, messages, max_tokens, tool_choice, response_format, reasoning_effort, parallel_tool_calls
- DeepSeek V4 Pro accepts no field the other one lacks.
- Only MiMo V2.6 Pro accepts: top_p, temperature.
- DeepSeek V4 Pro requires messages.
- MiMo V2.6 Pro requires messages.
- 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 deepseek/v4-pro/chat and xiaomi/mimo-v2.6-pro/chat, and both go in the same field of the same request.
Both return the response on the chat request. With streaming enabled, read the stream until it finishes; there is no media task to poll.
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?
DeepSeek V4 Pro allows 60 minutes per task and MiMo V2.6 Pro allows 10. Those are ceilings rather than typical times — most requests finish far sooner — but they are what your own client timeout has to survive.
