I’m currently using Grok 4.5 99% of the time now for both planning and tasks.
The fact that I don’t have to switch out to a cheaper model to do tasks means there is less context window model switching and faster speed.
Feels incredible.

SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities.

One very useful tool in Agent mode is image cropping of Grok Imagine .
I don't know why no one talks about it, as it is a crucial element for creating smooth transitions.
During a conversation, you need to frame each person and switch camera angles to add energy to your video.

Penny2x@imPenny2x· Jul 21, 2026Elon has repeated this over and over. "Everything will be free". The pickup is slow and few take him serious because humans are not good at visualizing exponential growth.
The truth is maybe not EVERYTHING will be free, like you can't own the entire galaxy for example. Nobody

Today we're announcing the completion of one of the largest engineering projects in the company's history:
We rebuilt the X Android app from scratch
It's faster, smoother and more reliable. But most of all: it will enable us to build new features at lightning speed.

Today is the 57th anniversary of Apollo 11 Moon Landing.
In 1969: most powerful technology on Earth = Apollo 11.
In 2026: most powerful technology on Earth = 2-trillion-parameter AI.
Which one changes civilization more?
