As the model gets better at writing code, the usefulness of abstraction layers designed to make things easier for humans trends to 0
I would probably be concerned with memory safety, but the models are already very good at identifying and fixing buffer overflows etc
Elon Musk@elonmusk· Jun 29, 2026@aaronburnett Truly massive gains will come in ~3 months when the entire training and inference stack is written in C/C++ and massively simplified (most software layers will be deleted completely) and we exact-map Grok to work incredibly well on a GB300

d this.
We wrote Telescript teleprompter software specifically in C and C+ to avoid the layers and “speak” directly to the firmware.
It was key in the early computer/video days (early 1990s) to have zero delays when important people depended on the words they had to say in

xAI is undertaking a major overhaul of Grok’s training and inference software stack. The core of this transformation is rewriting the entire system from high-level frameworks into C/C++, drastically eliminating intermediate abstraction layers, and performing exact mapping

In some cases, where we don’t have access to the source code, eg network switch software, we are also decompiling and modifying the binaries to improve performance

Projections 74 years into the future are a joke. The world will be completely unrecognizable much sooner than that. No one knows what’s going to happen.

Elon Musk@elonmusk· Jun 28, 2026@beffjezos In addition to their excellent and unique training data, the Cursor team is also making major engineering contributions to v9 SFT & RL. It’s an honor and a pleasure to work with them.
For this 1.5T run, Cursor data was added in supplemental training, which is not quite as good

Let’s see what calling in the aerospace/rocket engineers to work on AI models does for Grok.
Elon Musk@elonmusk· Jun 28, 2026@beffjezos To be clear, I’m not saying the Grok v9 foundation model will be mind-blowingly better than anything, but it will be a solid workhorse in the same league as Opus.
And the SpaceXAI cadence of model and harness improvement is speeding up tremendously, particularly due to a few

Our estimates for Starlink capacity/revenue are among the most bullish in the industry. The more I dive into the AI compute side the more I’m realizing we likely underestimated Cursor/grok.
Shay Boloor@StockSavvyShay· Jun 28, 2026$SPCX is expected to approach ~$100B of revenue by 2028 which would make SpaceX one of the fastest-scaling businesses in the world at this size.
The reason that ramp is even possible is that SpaceX controls the launch layer, uses that launch capacity to scale Starlink, uses

Andrew Carnegie spent a fortune building 2,500 free libraries so a poor kid could read what a rich one read. We are finishing the job he started. The only difference is the library now talks back, in every language, and it never closes.
