What happened
On July 8, 2026, xAI released Grok 4.5. The company, now branded SpaceXAI, calls it its smartest model so far. It is built for coding, knowledge work, and agentic tasks. 'Agentic' means the AI can carry out multi-step jobs on its own. xAI trained Grok 4.5 alongside Cursor, a popular coding app, and shipped it inside Cursor at launch.
The context
xAI sits near the back of the frontier pack today. A strong new model helps it stay in the race with OpenAI, Anthropic, and Google.
