Grok

SpaceXAI's models, strong on long-running engineering tasks.

Grok is SpaceXAI's model family, sold through its own API rather than published as weights. The recent versions are pitched at coding and agentic work — long software-engineering runs where the model checks its own output — and take text, images and files with a 500K-token context. Closed weights and paid only, so treat it as a frontier option you rent, not one you host. The Grok chat app is listed separately under Chats.
