On the official website of x.ai you can find this:
We are thrilled to unveil an early preview of Grok 3, our most advanced model yet, blending superior reasoning with extensive pretraining knowledge.
You can find a simle and good example with python and pygame how this can be used.
The Grok 3 artificial inteligence is used for :
Research
Brainstorm
Analyze Data
Create images
Code
For me, the artificial intelligence help me to be more fast into coding versus issues and bugs, game design, parse and change data.
I don't test this Grok 3, but I can tell you some artificial inteligence into develop area are bad even they say is dedicated to this issue.
