Configure the connection

These settings apply to SillyTavern extensions that support a custom NovelAI endpoint. The built-in NovelAI image source uses fixed official hosts; replacing only the API key does not connect it to this service.

Create an API key →
FieldValue
API formatNovelAI
Base URLhttps://noveadream.com
Full generation URLhttps://noveadream.com/ai/generate-image
API KeyEnter your NoveaDream API key.
Model (NAI5)nai-diffusion-5-full
Model (NAI4.5)nai-diffusion-4-5-full

Use the site root when the extension asks for a base URL, or the full /ai/generate-image URL when it asks for a complete endpoint. Key fields typically take the raw key; HTTP requests use Authorization: Bearer YOUR_API_KEY.
