Chub AI Setup Guide
Set up Api.Airforce as a reverse proxy inside Chub (chub.ai / Chub Venus) — OpenAI- and Anthropic-compatible.
Account & API key
If you don't already have one, create a chub.ai account and sign in. In parallel, generate an API key in your Api.Airforce dashboard — you'll need it in the next step.
Enable the reverse proxy in Secrets
Open the ≡ menu in Chub (top right) → Secrets → OpenAI. Turn on Reverse Proxy and fill in the fields as shown below. The URL must be the base URL (ending in /v1), WITHOUT /chat/completions — Chub appends the path itself.
Reverse Proxy: ON
OAI Reverse Proxy URL: https://api.airforce/v1
API Key: YOUR_AIRFORCE_API_KEYNote: once saved, Chub hides the API key in plain text. Verify the connection immediately after saving.
Pick a model in the chat configuration
Open Configuration → Prompt Structure. Set API to "OpenAI" and pick an entry from the Model dropdown such as gpt-4o or gpt-4.5. Chub forwards this model name to us verbatim.
Tip: Model alias for roleplay models
Chub uses a fixed model dropdown — no free text. To use our roleplay models (claude-sonnet-4.6-rp, deepseek-v3.2-speciale, etc.), create a Model Alias in your Api.Airforce dashboard (e.g. gpt-4o → claude-sonnet-4.6-rp) and then simply pick gpt-4o in Chub.
Create a Model Alias in the dashboardUse Claude natively (optional)
Want to use the Anthropic protocol directly? Open Secrets → Anthropic and enable the reverse proxy the same way. Here the URL is the bare base https://api.airforce (without /v1).
Anthropic Reverse Proxy: ON
Anthropic Reverse Proxy URL: https://api.airforce
Anthropic API Key: YOUR_AIRFORCE_API_KEYCheck proxy & start chatting
Click Check Proxy in Chub — a green check means the connection works. Then open a character and start chatting. If you get empty replies, verify that the model name picked in the Chub dropdown actually exists on our side (or is mapped via a Model Alias).
Known limitations
Chub only uses chat-completions — no embeddings or image generation via this proxy. The model dropdown is fixed, so Model Aliases are recommended. Top-K is ignored by Chub.

Want more control?
SillyTavern accepts free-text model names (no alias needed), finer prompt control, and custom presets. Often the more stable pick for demanding roleplay.
