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, research, finance, legal work, or anything else you do on a computer, we want to hear how it went. How does it handle long-running, multistep tasks? Grok 4.5 was trained to investigate problems, use tools creatively, recover from mistakes, and verify results before calling it done. Does that match your experience? How does it compare to Composer and other frontier models in your day-to-day? Anything noticeably better (or noticeably worse)? It should be solving tasks in notably fewer steps; let us know if you’re seeing that. This is also our first model trained jointly with SpaceXAI, and the kind of multistep, tool-heavy work it’s built for is exactly what’s hardest to capture in a benchmark, so your feedback shapes where the model goes next. Drop your thoughts below (and leave a Request ID if you have one)! We read everything. :folded_hands:

There’s also this article which Digital Ocean recently shared. So for me, Grok is not an option until I see something concrete on their privacy and git stance.

Grok Build is a separate SpaceXAI product and is not part of Cursor. The incident you referenced does not change how Cursor handles data when Grok 4.5 is selected in Cursor! [image] Colin: Cursor Grok 4.5 is subject to the same Privacy Mode controls as other models offered in Cursor. With Privacy Mode enabled, Customer Data is not used for training by Cursor or model providers, and Cursor maintains zero data retention agreements with model providers for ZDR-supported models.

Grok is being forced as the model every time I open a new chat. Is this being fixed? EDIT: I see there’s an acknowledgement that it’s a bug in Grok re-enables itself after being disabled in Settings . Please post in this thread too when that bug is resolved.

Used Grok 4.5 It is not useful for me. I personally prefer Composer 2.5 over Grok 4.5.

Hi @Charles_Wood , I noted this recently in Feedback - Don't change my default model (I suspect this is intentional on Cursor’s part, but I object to it).

I have had my fair share of rage moments with cursor and composer at times. At times so bad that I thought about switching to something else. However Cursor Grok 4.5 really hit the spot. It is extremely good for the price and I am not sure Opus 4.6 (which I still use as I think its better then 4.8) could beat this. I am very pleased with this model hopefully it stays as a default model that can be used alongside composer 2.5. Is that the plan ?

I would be tempted to do this for personal projects. If only there were a way to set this per repo (work private, personal shared)

I am not using it for anything, but Cursor keeps trying to force me to use it. I have removed all Musk products from my model list. That is, I set all the switches to OFF. Yet, when my current model of choice GPT-5.5 hits a limit, Cursor re-enables grok on the model list and switches my account to it. This is 100% a deal killer. It has happened six times so far. I will not fund Musk enterprises and neither will my company. if it means I have to drop Cursor completely, then so be it. I have reported the problem, but have yet to see any progress toward a solution.

I’ve been using it as the primary model after hitting limits on api usage due to fable. Its been pretty good so far, a bit slower than composer but a point up in quality of results. The major issue with cursor grok is that it doesnt know how to ask questions via the UI selector, it always asks them through the chat so you have to write out all your responses rather than selecting from the UI.

This bug was opened 8 days ago – Grok re-enables itself after being disabled in Settings . So I’m sure they’ll fix it eventually but they’re not in any hurry.
