Making Sense of the World

Cerebras finally goes public. $CBRS opened at $385 a share, far above the pricing of $185, giving the company a market cap of nearly $83 billion, similar to Monster Energy and UPS. For those who still don’t know what they do, they design AI chips like the WSE-3 (short for Wafer-Scale Engine) and build it into systems like the CS-3 and even entire supercomputers for customers who want to build on-prem AI. They also run their own inference cloud, operating six datacenters with thousands of CS-3 systems.
Musk v. Altman reaches its final day. In closing arguments, Musk’s lawyers questioned the integrity of Altman and Brockman and tried to show that they abandoned OpenAI’s original mission. OpenAI’s lawyers argued that Musk tried to turn OpenAI into a for-profit as well. Altman and Brockman were both present, Musk was not (he is on Trump’s trip to China). The jury will begin deliberation tomorrow. Kalshi predicts Musk has just a 30% chance of winning.
Chip exports to China are back. After the recent Trump-Xi summit, the US cleared about 10 Chinese firms (including Alibaba, Tencent, ByteDance, JD, Lenovo, and Foxconn) to buy the Nvidia H200, the company’s second-most powerful chip. No sales have yet been reported.
OpenAI Codex (finally) comes to mobile. You’ll now be able to start new tasks, review outputs, approve next steps, and more all from the ChatGPT app on iOS or Android while Codex runs on your laptop or devbox.
Mythos finds bugs in macOS. Researchers at security company Calif used Mythos to find a privilege escalation exploit in macOS, an operating system known for its lack of exploits. Another testament to AI’s rising cyber capabilities.
Anthropic announces a $200 million partnership with the Gates Foundation, focusing on “programs in global health, life sciences, education, and economic mobility”, though OpenAI’s $200 billion nonprofit endowment puts this to shame.
OpenAI and Apple are going through a rough spot. OpenAI is considering suing Apple for breach of contract after Apple announced a new partnership with Google on Siri. OpenAI has also been recruiting heavily from Apple’s hardware division to work on their own devices under Jony Ive, once Apple’s chief design officer.
AI is still unpopular. UCF arts and humanities grads booed a commencement speaker who tried to tell them that AI is the next industrial revolution. Plus, a new Gallup poll finds that 71% of Americans (63% of Rs and 75% of Ds) oppose building data centers in their area. The most common reasons cited were water usage, energy usage, energy costs, and AI replacing human workers.

Today’s Drop

We’ve all seen the increase in RAM prices over the last few months. The 64 GB of RAM that I bought last September for $205 now costs a whopping $940 on Amazon. Downstream consumers aren’t safe either, with prices of everything from the Mac mini to the Nintendo Switch 2 rising. Memory manufacturers everywhere are pivoting production from consumer RAM sticks to much more profitable high bandwidth memory for data centers. So why can’t they just increase their production so everyone can have some RAM? We explain why in our latest drop at memory.mts.now.
