Grok 4.5 is SpaceXAI's smartest model built for coding, agentic tasks, and knowledge work.
<p>xAI's Grok 4.5 just shipped, and the main takeaway isn't just its performance, but its sharp focus on developer economics. With significantly lower token counts on coding tasks and aggressive pricing, it's a direct challenge to the cost-per-task of established models.</p> <h2>…
