xAI just brought Grok 4.5, its smartest coding model, to millions of GitHub Copilot developers across VS Code, Copilot CLI, and cloud agents. You can simply pick it from the model selector (though some enterprise accounts require an admin toggle first), or access it directly via xAI's console starting at $2 per million input tokens.
xAI just released Grok 4.5, its flagship model tailored for coding, agentic workflows, and knowledge work. Trained alongside Cursor on tens of thousands of NVIDIA GB300 GPUs, it delivers 80 TPS generation speed and double the token efficiency of rivals, priced at $2 input and $6 output per million tokens. It is currently available with temporary free access in Grok Build and Cursor.
Elon Musk just announced that xAI will release Grok 4.5 to the public tomorrow following positive beta feedback. Musk described the new release as an Opus-class model that runs faster, is more token-efficient, and costs less than existing top-tier competitors.
Elon Musk just revealed that Grok 4.5 is now in private beta across SpaceX and Tesla. The 1.5 trillion parameter model incorporates Cursor data during training, with early evals reportedly rivaling or beating Claude Opus. Musk also claims SpaceX will roll out scratch-trained models every month this year.
