Belong AI Deploy
AI Providers
Give your agent a brain — connect ChatGPT, Claude, Gemini, or Kimi with OAuth or an API key.
AI Providers
Your agent needs an AI brain. Choose one (or more) of these providers. When you sign in with OAuth, your existing subscription covers usage — no extra per-message billing.
ChatGPT (recommended)
Default model: GPT-5.5
OAuth (recommended)
- Click Sign in with ChatGPT in the wizard
- Log into your OpenAI account
- Authorize the app
- Your existing ChatGPT subscription covers usage — no extra API billing
API key (fallback)
- Go to platform.openai.com/api-keys
- Click Create new secret key
- Copy the key and paste it in the wizard
API key usage is billed per message, separate from your subscription.
Claude
Default model: Claude Opus 4.8 (1M)
OAuth (recommended)
- Click Sign in with Claude in the wizard
- Log into your Anthropic account
- Authorize the app
- A local billing proxy on your deployed gateway keeps usage on your Claude Pro/Max plan
If you finish Claude setup from Telegram or WhatsApp after deploy, the bot sends a browser sign-in link. Copy it into Safari, Chrome, or your normal desktop browser instead of opening it inside the messenger — messenger browsers cannot finish this login reliably. Paste the final redirect URL or one-time code back to the bot. Never paste an Anthropic API key or OAuth bearer token into chat.
API key (fallback)
- Go to console.anthropic.com/settings/keys
- Click Create Key
- Copy and paste it in the wizard
Gemini
Default model: Gemini 3 Deep Think
Gemini uses API keys only (no OAuth).
- Go to aistudio.google.com/apikey
- Click Create API Key
- Select or create a Google Cloud project
- Copy the key and paste it in the wizard
Built-in media defaults after deploy: image generation uses google/gemini-3-pro-image-preview (with google/gemini-2.5-flash-image as a fallback), and voice-note transcription is handled natively.
Kimi
Default model: Kimi K2.6
Kimi uses API keys only.
- Go to platform.moonshot.cn/console/api-keys
- Create a new API key
- Copy and paste it in the wizard
Subscription vs. API-key billing
| Method | How it works |
|---|---|
| OAuth (subscription) | ChatGPT uses native subscription auth. Claude uses a built-in billing proxy on your deployed gateway, so usage stays on your plan. |
| API key | You pay per message based on the provider's pricing. |
If you have a ChatGPT Plus/Pro or Claude Pro/Max subscription, OAuth is the better option.
