One command launches the tool through Antseed. Your projects, chats, and settings stay the way they were.
Your local endpoint at localhost:8377 speaks the OpenAI and Anthropic APIs. One command launches your tool through it.
Your coding app talks to localhost. There is no account or API key on file, so no one can tie a session to you.

Learn moreNo. Keep it if it earns its price. When the plan’s window runs out, launch the same tool through Antseed and keep working, then switch back whenever you like. Nothing about your projects or settings changes between the two.
The live board lists what providers serve, including frontier models, each at the provider’s own price. Every response is signed by the provider and matched against the model’s fingerprint; providers who serve something else lose reputation and stop getting routed. How verification works →
Yes, through a public endpoint. Some Cursor requests come from Cursor's own servers, which cannot reach your localhost, so publish an authenticated HTTPS endpoint from the AI VPN, then in Cursor's model settings paste the Antseed key as the OpenAI API key and the endpoint as the OpenAI base URL.

Leave it on auto and every request goes to the cheapest verified provider for the model your tool asks for. To pin a model for one run, pass --model <id> to the wrapper, using an id from curl http://localhost:8377/v1/models. To pin a specific provider, use <peerId>@<model>. More questions in the FAQ →
