SillyTavern
Use NavyAI as the backend for SillyTavern. Point SillyTavern's Chat Completion API at NavyAI's OpenAI-compatible endpoint with your NavyAI key, then pick any model from the catalog.
Connect via Chat Completion (recommended)
- Open SillyTavern and click the API Connections (plug) icon
- Set API to
Chat Completion - Set Chat Completion Source to
Custom (OpenAI-compatible) - Set Custom Endpoint (Base URL) to
https://api.navy/v1 - Paste your NavyAI key (
sk-navy-...) into the Custom API Key field - Click Connect — available models load automatically; pick one from the Model dropdown
Anthropic-native alternative
If you prefer SillyTavern's Claude chat completion source, enable its Reverse Proxy option, set the proxy URL to https://api.navy and use your NavyAI key as the proxy password. Both routes hit the same models — the Custom (OpenAI-compatible) source is the simpler default.
Picking a model
Any model in the NavyAI catalog works. Popular roleplay picks include claude-sonnet-4.6 and claude-opus-4.6 for prose quality, gemini-2.5-pro for long context, and claude-haiku-4.5 for fast, cheap swipes. Browse everything with:
1curl https://api.navy/v1/modelsPremium models are marked with premium and required_plan in the catalog — the dashboard shows which tier your subscription unlocks.
Tips
