What it does

Blackbox is an inference platform. It routes requests to more than 300 open and closed models through one endpoint, and it runs open-weight models in dedicated, single-tenant deployments. The site describes end-to-end encrypted inference, zero data retention, deployment on Microsoft Azure, and enterprise options such as SSO and SAML. Visitors can create an account, read developer documentation, use the API, or contact sales.

Developer documentation describes a chat completions endpoint at https://enterprise.blackbox.ai/chat/completions, called with a bearer API key, and covers messages, tool calling, streaming, images, and provider routing. Model prices are listed on an LLM pricing page. The contact page carries a sales form and the address [email protected], and states a first reply within one business day. The listed office is Blackbox AI Technologies Inc., 535 Mission Street, San Francisco. The site states that training opt-out is on by default and enforced with upstream providers.
