Your own keys
Add a key under Settings → Models & keys and it appears in the model sheet as a row with a price. Keys are free on every plan and never count against the window.
What you can add
| Provider | How |
|---|---|
| Anthropic | Paste an Anthropic key. |
| OpenAI | Paste a key; the preset points at api.openai.com. |
| OpenRouter, Groq, Together, Mistral, DeepSeek, xAI | Presets with the right base URL — paste the key, pick a model. |
| Ollama or LM Studio on your machine | Presets for localhost:11434 and localhost:1234; no key needed. |
| Anything OpenAI-compatible | Enter a base URL, a model id and (if it wants one) a key. |
What the key can see
When you use a key, your prompt and the files the agent reads go to that provider and nobody else. OIOXO’s servers are not in the path. The provider’s privacy terms govern that traffic.
Where it is stored
Keys and GitHub tokens are encrypted in a secure store under a key that cannot leave this browser. That is why Settings → Your settings on another device exports everything except keys: the file could only carry ciphertext nothing else can read, or your live keys in plaintext in a Downloads folder. Add the key again on the next device.
Cost
The row shows the provider’s price per million tokens, and while a key is active the chat header shows the running cost. Stop always aborts; a stopped request stops costing.
A key does not need Pro, and Pro does not change what a key can do. The two are separate: Pro is about OIOXO models; keys are yours.
