RisuAI

RisuAI connects through its Custom API model (OpenAI Compatible format). On the web version, turn on Force Plain Fetch so requests go straight to FreeTheAI.

Category: Roleplay apps. Before you start, you need a FreeTheAI account, an API key, and today's check-in.

Steps ​

Open the bot settings ​

Open Settings (gear), then Chat Bot.

Choose Custom API ​

Set the model to Custom API and the format to OpenAI Compatible.

Fill in the connection ​

Enter the URL, your key in Key/Password, and a model ID in Request Model, using the values above.

Web version only: Force Plain Fetch ​

Go to Settings, Advanced Settings, turn on Show Unrecommended Settings, then turn on Force Plain Fetch. Without it RisuAI sends requests through its own relay, which FreeTheAI does not accept.

Tips ​

  • A base URL ending in /v1 also works; RisuAI adds /chat/completions.
  • The desktop and mobile apps do not need Force Plain Fetch.

Common questions ​

RisuAI says relay_not_supported. How do I fix it? ​

Turn on Force Plain Fetch under Settings, Advanced Settings (after enabling Show Unrecommended Settings). RisuAI then calls FreeTheAI directly from your browser.

Which model should I use? ​

fta/zai/glm-5.3 is a strong default for roleplay. See freetheai.org/models for all free models.
