Grok 4.3 is a new pre-trained model matching the scale of Grok 4.20 with an improved architecture and a December 2025 knowledge cutoff. Rolling out now to SuperGrok and Premium+ subscribers.
Starting with Grok 4.3, Grok has access to the same kinds of tools, data, and environment that you would want if you were sitting down to do real work.
Create presentations, documents, and spreadsheets
Grok now has access to a computer where it can write code, run it, install what it needs, and produce real files.
What's next
This is the beginning. We are working on giving Grok full access to the internet, your files, your email, your calendar, and any service you can connect to. The goal is simple - if it would be useful for a person to have access to something, Grok should have access to it too.
