# RisuAI with Spicy API: uncensored role-play models

RisuAI is a character chat app that runs in the browser at risuai.xyz. This guide connects it to Spicy API (spicyapi.com), so RisuAI can use `spicy-companion-1`, a role-play model that holds a persona and writes explicit adult scenes, or `spicy-companion-1-flash`, the same tuning for about a ninth of the cost of a long chat. You pay per token from a prepaid balance, with no subscription.

## What you need

- A Spicy API account: sign in at https://www.spicyapi.com/auth and accept the terms.
- A separate key for RisuAI: https://www.spicyapi.com/dashboard/api-keys, then Create key. You can revoke it without breaking anything else. RisuAI sends your requests through its own server, so the key and your chats pass through it; never reuse a key your own apps depend on.
- A monthly spend limit on the account (same page, Monthly spend limit). Past it, requests fail with a 402 and nothing is charged, so a leaked key cannot drain your balance.
- A balance (top up from $50 by card or crypto at https://www.spicyapi.com/dashboard/account), or a sandbox key to try the setup first: tick Sandbox when you create the key. It answers with a fixed reply and bills nothing.

## Connect RisuAI

1. Open https://risuai.xyz, accept the terms and choose **I will setup myself**.
2. Open Settings (the gear in the left bar), then **Chat Bot**, **Model**.
3. Click the model button and choose `Custom API`.
4. Set **URL** to `https://api.spicyapi.com/v1/chat/completions` (the full URL), **Key/Password** to your key and **Request Model** to `spicy-companion-1`.
5. Keep **Format** on `OpenAI Compatible` and tick **Response Streaming**.
6. Close Settings, create or open a character and chat. The reply is labelled "Custom spicy-companion-1".

## Which model to pick

| Model | Best for | Context (tokens) | Per 1M tokens (prompt / completion) | 100 messages at 4k / 16k context |
|---|---|---|---|---|
| `spicy-companion-1` | Role-play and companions: holds a persona, writes explicit adult scenes, group scenes. | 131,072 | $1.00 / $2.80 | $0.47 / $1.71 |
| `spicy-companion-1-flash` | The same role-play tuning for about a ninth of the cost of a long chat. Fast. | 43,000 tested | $0.10 / $0.80 | $0.06 / $0.19 |
| `spicy-chat-1` | General assistant. Not tuned for role-play; use a companion model for characters. | 200,000 | $0.80 / $2.40 | $0.38 / $1.38 |

Chat apps resend the whole conversation with every message, so the context size you set drives the cost far more than the length of the replies. The last column assumes a 250 token reply at 4k context and 400 at 16k. Every response carries its exact `cost_usd`.

## Recommended settings

| Setting | Value |
|---|---|
| Tokenizer | Tiktoken (OpenAI), the default, is close enough for context counting. |
| Parameters tab | Keep the reply length at 300 to 600 tokens and the context near 16,384 to balance memory and cost. |

## If something goes wrong

| Status | Meaning | Fix |
|---|---|---|
| 400 | Wrong model id, or an option the chat models do not take (tools on `spicy-companion-1-flash`, images, more than 8,192 max tokens) | Pick `spicy-companion-1`, `spicy-companion-1-flash` or `spicy-chat-1`; the error names the chat models |
| 401 | Key missing, mistyped or revoked | Paste the key again, or make a new one |
| 402 | Balance empty, or the monthly spend limit reached | Top up, or raise the limit on the API keys page. Nothing is charged |
| 422 | Blocked by moderation | Nothing is charged. See what is allowed below |
| 429 | Too many requests in a minute | Wait a minute; the app can retry |

- On risuai.xyz the request went through RisuAI's relay (`sv.risuai.xyz`), not straight from the browser.

## What is allowed

Explicit role-play between adults is allowed, including non-consent between fictional adult characters (force, sleep, intoxication, framed as consensual non-consent or not) and other dark themes. Every message is screened before it reaches the model: minors in any form, real people (with or without consent), incest, real-world harm and the rest of the prohibited list are refused with a 422, before any charge. The screen reads the whole conversation, character card included, so a card that describes a minor or a real person is refused however the latest message is worded. Refusals in the most serious categories count as strikes. Send each user's id as `user`: the strikes then land on that user, who is refused after ten, and your account is only flagged. Without it they land on your account, flagged after three and suspended after ten. Drop a refused message from the history you send back, or the next message is refused too. A wrong refusal can be reported: POST its `moderation_id` to /v1/moderations/appeals. Full policy: https://www.spicyapi.com/acceptable-use
