    "Really big step up for Grok AI models"

    5 out of 5 stars Posted 2026-07-09

    Pros: Grok 4.5 is really impressive from the perspective of a developer and AI agent builder. It feels built for the stuff I actually care about: coding, tool use, agentic workflows, debugging, refactoring, and getting real work done instead of just chatting. I especially like that it seems focused on speed and cost efficiency, because those two things matter a lot when you are running agents over and over in production-like workflows.

    Cons: It still feels early, and I would want to test it hard before trusting it as the backbone of serious production agents. Benchmarks and launch claims are useful, but they do not always translate perfectly into messy real-world codebases, weird edge cases, long-running tasks, and tool-heavy workflows. I also want to see how reliable it is across longer sessions, especially when an agent has to stay on track through multiple steps without drifting.

    Overall: Five stars from me. Grok 4.5 looks like a serious step forward for developers who are building AI agents, coding assistants, and automation-heavy workflows. The mix of coding strength, agentic focus, API availability, Cursor support, and lower-cost positioning makes it one of the more interesting models to build with right now.
