Grok 4.5 Has Finally Dropped!
Just moments ago, Elon Musk’s xAI made a bombshell announcement: the release of its strongest flagship model yet — Grok 4.5.
This time, xAI teamed up with Cursor in a powerful collaboration.
Trained on tens of thousands of GB300 GPUs, they forged a true performance monster purpose-built for coding and agentic workflows.
The report card is impressive:
SWE Bench Pro: 64.7% — surpassing Opus 4.7’s 64.3%
Terminal Bench 2.1: 83.3%
DeepSWE 1.0: 62.0% — crushing Opus 4.8
Musk himself stated: “Grok 4.5 is roughly equivalent to Opus 4.7, but much faster.”
Its real competitiveness lies in the combination of capability, speed, and cost. In other words, it gets the job done using only a fraction of the tokens others need.
Pricing:
Input: $2 per million tokens
Output: $6 per million tokens
Compared to Opus 4.8, Grok 4.5 consumes 4.2× fewer tokens.
