The newest Grok model from Elon Musk is advertised as a coding and engineering model and is now the default model in Grok Build and Cursor plans.

Elon Musk said the latest version of Grok is “faster, more token-efficient and lower cost” than one of Anthropic’s models.

Grok 4.5 is SpaceXAI's smartest model built for coding, agentic tasks, and knowledge work.

There are a lot of new AI models out this week.
