The upcoming wave of SpaceXAI Grok updates is insane
Grok 4.5:
The 1.5T foundation model is being refined almost daily, and its context window is expected to jump to 1M tokens, possibly as soon as next week
Next model:
The 2T foundation model is expected to finish training this month and become available to customers next month
Grok Build:
The harness is getting refinements almost every day based on user feedback. New features, fixes, and workflow improvements are landing at ridiculous speed
Inference:
SpaceXAI is working on internally developed C/C++ inference mapped directly to GB300 hardware, which could double speed or more
Agentic Imagine:
Grok will be able to call Imagine as a tool in agentic mode for image and video generation
That is going to be huge for game developers, designers, builders, and anyone creating interactive worlds
But the biggest thing is this:
Grok is being built for real-world engineering
Grok 4.5 early beta access was given to Tesla and SpaceX engineers, with feedback coming from real engineering teams solving real-world problems
Next month’s release is expected to be another massive step-change improvement as SpaceXAI closes the loop on real-world engineering problems at Tesla, SpaceX, Neuralink, and Boring Company
And from now through the end of 2026, Elon said a new from-scratch foundation model is expected to ship every month
