Connect your own API keys for model providers so chats using those models bypass AgentSky's billing for that model.
Vendor accounts (also called Bring Your Own Key) let you supply your own API key for a model provider. When AgentSky routes a chat through your key, model token costs are charged to your provider account, not your AgentSky balance.
- Open Settings › Agents and apps › Bring your own subscription.
- Click Vendor accounts.
- Add your API key for the relevant provider.
Where: Settings › Agents and apps › Bring your own subscription › Vendor accounts (web and Mac).
Good to know: BYO API keys and BYO subscriptions (Claude/ChatGPT plans) are separate — you can use either or both. You still need AgentSky credits for compute, tools, and connectors regardless of which model billing you use. Related: Connect a Claude or ChatGPT plan, How billing works.
