Europe is so cooked. Literally and figuratively. Joking aside, I have a theory. That continent has fought itself stupid. Napoleon, WWI, WWII, etc. Since 1800, 120+ million people have died on that continent due to war. Usually the finest stock of a country goes to war, so

The fact that the entirety of Europe is willing to sacrifice a notable amount of their population to a Covid-esque purity spiral is a pretty good indication that no lessons were or will be learned

VW plans to end its self-driving partnership with auto supplier Bosch as part of a wider push to cut costs and ‌after VW determined the technology was not competitive with other self-driving systems such as @Tesla's FSD. This follows a report that VW plans to cut 100,000 jobs

Back then we thought of C as being wasteful compared to assembly code. Interesting that C/C++ now is the fast code to get back to.

😂💯 We are using some assembly (and direct ASIC primitives) for operations that are done trillions of times per second

The more I use Grok and Grok Build, the more I think about (and am pained by) how insanely LOW BANDWIDTH human communication is. Really wish could dump what's in my brain about 1000x faster. I've switched to voice prompting for speed but it's still way too slow. (Neuralink has

@elonmusk · Jun 29, 2026

Neuralink is needed to solve the super low & lossy output bandwidth of humans. Our input bandwidth, thanks to vision, is many orders of magnitude higher than our output bandwidth, but could also be greatly improved. By addressing these bandwidth limitations and greatly increasing our effective cognitive capacity, human-AI symbiosis will be far better, improving the probability of a great outcome for humanity in the future.

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

@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

Same. I worked video games in the 90s with no graphics accelerators. Every CPU clock cycle mattered.

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

@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

@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
