@Emmanuel, @matjaz with the release of Xai (grok), I thought I would test it out.
The docs say the endpoint is compatible with the OpenAI API.
Early days of playing with it, but I get the occasional error (not supporting function calls), so I am not sure about the End Point I have defined. I am certain it is wrong, I played with some of the other end points.
Do you have some suggestions here?
@PeteSharp add |tools after the model name, or |vision|tools
For example:
grok-beta|tools|vision
Thank you @matjaz, so the end point is ok as it is then.
And So? Success? Failure? Mixed results? 
Haven’t done too much yet, but early test, Grok was not that great with layout. Content was ok. It’s very fast.
I think Grok 2 is suppose to be better code wise.
I will do some more tests soon, I didn’t want to mess with a current project I was working on too much.
If you sign up for the xAI you get $25 worth of tokens free. So give it a go @Emmanuel if you have some time.
