# Grok 4.5 Launches as xAI's Most Capable Model for Reasoning and Coding

> xAI has launched Grok 4.5, which it bills as its most capable model yet for reasoning and coding. The headline claim is efficiency: xAI says the model achieves roughly 2x the token efficiency of comparable leading systems, and Elon Musk asserts it is faster and more cost-effective than Opus. Pricing lands at $2 per million input tokens and $6 per million output tokens. Availability is broad from day one. Grok 4.5 is accessible through Grok Build, the xAI console, and notably inside Cursor, the popular AI coding editor, which puts it directly in front of developers where they already work. The company also says Grok Imagine, its image and video generation tool, is finished, with EU availability expected in mid-July. Whether the efficiency claims hold up under independent testing is the usual caveat with vendor benchmarks. But the competitive pressure is real. By undercutting rivals on price and slotting into tools developers already use, xAI is trying to buy its way into daily workflows rather than just topping a leaderboard. In a crowded field, distribution may matter more than bragging rights.
