About BigModel.io
BigModel.io is one API for the world's big models: one key, prices in US dollars, no overseas card required.
BigModel.io is one API for the world's big models. Developers get one key for OpenAI- and Anthropic-compatible APIs, prices in US dollars with the official price alongside, and payment by Alipay or USDT, with no overseas card required.
What we do
- One API key and one USD balance for every model we sell; more model families are added as developers vote for them.
- OpenAI- and Anthropic-compatible endpoints, so existing SDKs and coding tools work unchanged.
- Published prices with the official price alongside, and a public status page.
