# Welcome to AIOHub

> AIOHub is a unified API gateway for AI models, with OpenAI-, Anthropic-, and Gemini-compatible endpoints.

AIOHub brings major AI models together on one platform — you can chat directly in the browser or connect through the API with your own tools.

<Tip>Usage-based billing is available, and monthly subscription plans are also supported. AIOHub can issue mainland China VAT special/general invoices and Hong Kong invoices. These are compliant invoices that can be used for business reimbursement. [Learn about payments and invoices ->](/en/account/recharge)</Tip>
