Main announcement · Blog Now that Grok 4.5 is available, we’d love to hear how it’s working for you. Some things we’re especially curious about: What are you using it for beyond coding? This is the first model we’ve built for more than software engineering. If you’ve pointed it at data science…

if i choose “Auto” Model that mean the agent will use composer 2.5 or grok-4.5 to excute?

The model is definitely faster than Composer 2.5, and I really like that. My biggest issue is that it doesn’t seem to understand what I’m actually asking very well. I often have to make my prompts extremely explicit before it gets them right. Even then, it tends to complete the task literally inste…

Everything seems to be great so far and it has barely touched my usage, to the point that I’ve double-checked on the website that …

Sorry for two posts in a row, but after working more deeply with Grok 4.5 last night and today, I’m sold. The performance is amazing for the cost. It seems to have access to more interesting tools (maybe I’m wrong about this?): it recently (correctly) traversed an open api using cURL and wrote ap…

This is a fantastic model—I’ve already built some really cool things with it in Rust and Python. The only thing I’m still wondering is: SpaceX AI is the new owner of Cursor, right? When you use SpaceX AI’s official API, the context window goes up to 512k tokens, but here in Cursor it’s only 256k tok…
