xAI's update timing is very clever, just right before the GPT-5 rumors.

The beta version is only available on the official website and does not provide an API, so developers will complain again.

Grok 4.3 This version number jumps a bit interestingly, jumping directly from 4.20 to 4.3, I’m amazed by the naming logic of xAI.

How long can the specific context length be? Hopefully not limited to PPT parameters.

Long-context understanding + native video comprehension—if these two are truly perfected, Claude and GPT will face significant pressure.

It’s only been two months since the 4.20 update, and Musk’s pace is crushing the competition.

Multimodal video understanding is finally here. Previously, Grok was okay at image recognition, but it truly falls short when it comes to videos.

Early Access is also for paying users first? Free users will just keep waiting.
