ELON MUSK: We believe the AI5 chip will be roughly comparable performance to an NVIDIA Blackwell, and at much less than 10% of the cost Transcription: I'm super hardcore on chips right now as you may be able to tell. I have chips on the brain. I dream about chips, Literally! Because in order to have a functional robot, you have to have a great AI chip. And it needs to be an inexpensive chip and it needs to be very power efficient So we think we believe the AI5 chip will be probably about a third of the power of say something like a Blackwell, an NVIDIA Blackwell, which is a great chip, for roughly comparable performance. And much less than 10% of the cost. This is a chip that is very much optimized for the Tesla AI software stack. So it's not meant to be a general purpose chip, it's meant to be an amazing chip for the Tesla AI software And I mean a couple of things that I think make... like how is Tesla able to achieve such an improvement? I think it is because we are specialized. We're not trying to... you know, NVIDIA has to serve the superset of all past and future customers. So all of their requirements, all of the software that they've written has to work, which is a very difficult problem. Whereas we just need to make it work for our software. And so we're able to simplify the chip dramatically And then we also, I think we're unique in this, but like we have an integer-based system. And integer operations are fundamentally more efficient than floating point operations. So we can do floating point, but the vast majority of our inference is done in integer. Which is, if you're familiar with sort of logic gates, the simplicity of integer... it's integer is much more power efficient, much more silicon efficient, but you have to, you actually have to train for integer inference, which everyone else is training for floating point. That's kind of like a niche technical detail, but it's actually very important. So, yeah, this is going to be a great chip So this chip will be made in basically in four places: TSMC Taiwan, Samsung Korea, TSMC Arizona, and TSMC Texas. And we already know what improvements to make for AI6. So I'm hopeful that we can within less than a year of AI5 starting production, we can actually transition in the same fab to AI6 and double all of the performance metrics

This is where I have to share my raw feelings about Rivian software currently on R1. The software experience they have created is good. It’s their own, with their software stack that they control. With that said, we have to stop making excuses for longstanding bugs. Like Quinn Nelson had posted about long ago, having to do multiple Resets, logins and out to get core functionality to work is not the experience we should be having. I know Rivian and Wassym do not want this. I also know they are working on R2 stuff as well. As a person who has spent real money on 4 Rivian’s with 3 R2 reservation between me and hubby, we are huge fans. Have helped many become Rivian owners as well. But the long outstanding bugs are starting to boil over. It’s dragging the software reliability down. Apple Music has been in Rivian vehicles for just about 2 years now. We are past the stage of it being “new”. Spatial Audio is a key music feature, and for me, and plenty of others, you have to turn that off sometimes just to get music to play. I shouldn’t have to do that. Plus, you can’t change that feature while the vehicle is in drive. So then you have to pull over and fiddle with it just to get it work and sometimes it doesn’t. Rivian assistant can’t do it either. Among other issues, like HVAC preconditioning, unstable cabin temps, GPS locking issues, profile switching not getting right or switching profile after the driver has gotten in, mobile app live activities not functioning properly, and more. The live activities is important, because we don’t have a notification for charging start stop/complete except for charging complete on DCFC, so on a level 2 charger, I don’t know if there is an issue with charging if the live activities don’t appear. Same for HVAC if it’s not showing up I have to keep opening the app to check to see what the temperature is. If you aren’t going to push me a notification that the cabin is at the temp I selected in favor of the live activities, then the live activities has to work. I could go on, but I really love my Rivian. I love the brand, I love what they want to do. And I think R2 is going to change the market for most things, but I want their focus to be on software and stability. Focus on polish, focus on features that many people want, don’t over complicate those things. Example, valet mode should be here by now that locks down speed acceleration and access to certain parts of the vehicle. Basic Pin to drive, not the multi factors drive one that depends on your phone and vehicle having an internet connection. Speedy, clean, stable software is always a win. I know Wassym Bensaid and plenty of others at Rivian can do this. We have seen it before and seen what they can do. The YouTube app is by far the best app they have added. I haven’t had any issues with it. It’s responsive, and works. Everything needs to work like that across the board. Please guy let me help in anyway I can, I just want the best for you and the community and customers. Let’s focus on that. I know some will see this as a complete complaining post but it’s not. It’s a plead to make the experience better for everyone and making the Rivian software the best software it can be.

Doubling down on my $RIVN Investment! Here are all the reasons why: • Founder RJ (RJ Scaringe), an MIT grad, is brilliant, hands-on, and laser-focused on Rivian (not building 7 different companies) • Rivian is the ONLY other company (besides $TSLA) that has already built a full EV stack: - cutting-edge software - top-tier manufacturing - in-house battery tech - in-house electronics & FSD/AI hardware - in-house top-tier AI and full self driving team - in-house fast-charging network (similar to Tesla super chargers) • Rivian is the ONLY other company that is shipping an 8-camera surround view and powerful onboard computer for FSD in EVERY vehicle. They can collect enormous amounts of real-world video (2nd only to Tesla) to train their AI. Can’t believe no traditional car maker is doing this yet! • Rivian’s FSD/AI team is led by top talent making rapid progress on FSD using latest AI neural net techniques, similar to Tesla’s FSD v12+. • Rivian’s R1 Truck and SUV are both highly rated and loved by customers • Rivian’s Delivery van is a unique offering that is also loved by customers • Rivan’s R2 vehicle (to be launched in 2026) is intended to be high-volume and will likely be a great alternative to the Model Y and drive the company to profitability (note that it doesn't need to beat Model Y...the shift is from gas-cars to EVs). • Rivian’s $5.8B parnership with VW proves that Rivian is FAR ahead in software/tech/electronics than any other traditional car company (remember VW is the world’s largest car manufacturer and they still need Rivian’s help for EVs!) • Rivan’s ~$13 Billion market cap is RIDICULOUSLY LOW for a company that is as accomplished with real-world products that customers love. That said, there are RISKS with Rivian: • Scaling & production challenges could delay Rivian’s progress • They are still losing A LOT of money every quarter and if progress to profitability takes too long, they could run out of money and be forced to raise money at unfavorable terms. But if Rivian becomes a viable and profitable company, in say 5 years from now, producing 500K+ vehicles, it could easily have a $200 Billion valuation (less than 1/7th or 15% of $TSLA’s valuation TODAY!) That’s roughly a 1,500% potential upside, with just a 100% downside, making this bet well worth it for me, even if the probability of success is less than 50/50. So that's why I’m doubling down on $RIVN. 🚀

NEWS: NVIDIA just announced Alpamayo, what CEO Jensen Huang calls the world’s first thinking, reasoning autonomous vehicle AI, launching on U.S. roads later this year, starting with the Mercedes CLA. Jensen: "It's trained end-to-end. Literally from camera in to actuation out; It reasons what action it is about to take, the reason by which is came about that action, and the trajectory." Alpamayo introduces Vision-Language-Action (VLA) models, which enable self-driving systems to interpret what they see, reason about complex driving scenarios, and generate driving actions. The platform includes large reasoning models, simulation tools for testing rare and edge-case scenarios, and open datasets for training and validation. NVIDIA says the approach improves transparency, safety, and robustness in autonomous systems, particularly in complex real-world environments, and supports progress toward higher levels of vehicle autonomy: "With a 10-billion-parameter architecture, Alpamayo 1 uses video input to generate trajectories alongside reasoning traces, showing the logic behind each decision. Developers can adapt Alpamayo 1 into smaller runtime models for vehicle development, or use it as a foundation for AV development tools such as reasoning-based evaluators and auto-labeling systems. Alpamayo 1 provides open model weights and open-source inferencing scripts. Future models in the family will feature larger parameter counts, more detailed reasoning capabilities, more input and output flexibility, and options for commercial usage."

On Friday, I hosted a Space with Jonathan Ross, the founder and CEO of Groq Inc - a company I invested in that is building custom chips for AI inference. Jonathan, a former high-school dropout, entered the chip industry while working on ad optimization at Google’s New York office. Jonathan overheard the speech recognition team complaining that they couldn't get enough compute. These were the early days of AI, and machine learning wasn’t really a thing yet. So he asked for some budget from Google and started putting together a chip-based machine learning accelerator for them. During the day, Jonathan would work in the normal ads part of the business, and at night, he would work with the accelerator team. After winning approval from Google, Jonathan and his team built a new chip called the Tensor Processing Unit, and began deploying it across Google’s data centers within a year. The TPU was a huge success within Google, eventually underpinning more than 50% of all of Google’s compute power. When the other hyper-scalers learned of this success, they tried to hire Jonathan to build custom chips for them too. During this process, it became increasingly clear to Jonathan that a gap would emerge between companies that had access to next-gen compute and companies that didn’t. So he founded Groq and set out to build a chip that would be available to everyone. I led Groq’s founding investment in 2016, and since then, Jonathan and his team have developed several types of AI hardware including the Language Processing Unit (LPU), a new type of silicon that is hyper-efficient at running inference for LLMs. In our conversation on Friday, we discussed the founding story of Groq, what you need for great AI hardware, large language models, and some of the implications for the key players in AI. It’s one of the most interesting conversations I’ve had on AI with a lot of learnings. You can listen to our conversation below:
