@ohhanxiety 10-20% reality …. 40% is your dream and the end of any business that has wages so low that it needs 40% tips for its employees …

your critics are so dumb you don’t get paid until your goals are met some of the goals are almost impossible for my way of thinking so if you make them you deserve your compensation and the company gains impossible goals win win
I own a small amount of Tesla stocks and into my way of thinking if you can make all these goals yippee for me…

Elon Musk: At Tesla, we basically had two different chip programs: one Dojo and one. Dojo on the training side, and then what we call AI4, it's just our inference chip
The AI4 is what's currently shipping in all vehicles, and we're finalizing the design of AI5, which will be an immense jump from AI4. By some metrics, the improvement in AI5 will be 40 times better than AI4. So not 40%, 40 times
This is because we work so closely at a very fine-grained level on the AI software and the AI hardware. So we know exactly where the limiting factors are. And so effectively the AI hardware and software teams are co-designing the chip
Compared to the worst limitation on AI4, which is running the SoftMax operation, we currently have to run SoftMax in around 40 steps in emulation mode, whereas that'll just be done in a few steps natively in AI5
AI5 will also be able to easily handle mixed precision models, so you don't have it, it'll dynamically handle mixed precision. There's a bunch of sort of technical stuff that AI5 will do a lot better
In terms of nominal raw compute, it's eight times more compute, about nine times more memory, and roughly five times more memory bandwidth
But because we're addressing some core limitations in AI4, you multiply that 8x compute improvement by another 5x improvement because of optimization at a very fine-grained silicon level of things that are currently suboptimal in AI4, that's where you get the 40x improvement

grok reply to this:
**No, Tesla does not currently offer upgrades from AI4 (Hardware 4) to AI5 (Hardware 5) for existing vehicles.** This is because AI5 requires a completely redesigned motherboard, chip, and significantly higher power (2-3x more than AI4), along with new electrical and cooling systems that aren't compatible with AI4 vehicles without a major retrofit. Tesla has focused upgrades on older Hardware 3 (HW3) models in the past, but for AI4 owners, no such path has been announced, and experts expect it to remain unavailable due to these hardware constraints.
AI5 is slated for production vehicles starting around late 2025 or early 2026, delivering 3-5x (or even up to 40x in real-world performance) more capability than AI4, with around 2,000-2,500 TOPS of processing power. If Tesla achieves full autonomy on AI4 hardware through software optimizations, the need for upgrades could diminish, but that's still speculative. For now, AI4 remains sufficient for current Full Self-Driving (Supervised) features, which are expected to be 2-3x safer than human drivers.

@XFreeze I'm curious if people can upgrade their cars from AI4 to AI5?
