AMD UNVEILS NEW CHIP FOR CORPORATE DATA CENTERS, TALKS UP DEMAND

AMD's new MI440X chip is designed for use in smaller corporate data centers. The company's new Helios system, based on the new chip, will go on sale later this year. AMD's MI500 series of processors will debut in 2027. Those chips will deliver up to 1,000 times the performance of the MI300 series, which was first rolled out in 2023.

GROSS PROFIT PER TOKEN

Meta's $2 billion acquisition of Manus highlights the importance of gross profit per token, with Manus showing 40x GP multiple. DeepSeek and Together AI have the lowest multiples because they resell inference, unlike Perplexity, which achieves the highest at 222x as an application. Investors prioritize token monetization over raw volume, as indicated by a 0.71 correlation between gross profit per token and valuation.

AI CAPEX: BUILT ON OPTIONS, PRICED AS CERTAINTY

Letters of intents are real options that move markets, guide counterparties, and shape capex decisions before obligations harden. Options can be enough to pull forward tens of billions in irreversible investment. If the option doesn't convert, the stranded capital becomes a restructuring problem.

GRPO++: TRICKS FOR MAKING RL ACTUALLY WORK

Group Relative Policy Optimization (GRPO) is the RL optimizer used to train most open-source reasoning models. It is popular due to its conceptual simplicity and practical efficiency. The vanilla GRPO algorithm has subtle issues that can hinder the RL training process, especially at scale. This post provides an overview of the work done to solve the shortcomings of GRPO.

KERNELEVOLVE: SCALING AGENTIC KERNEL CODING FOR HETEROGENEOUS AI ACCELERATORS AT META

Making deep learning recommendation model (DLRM) training and inference fast and efficient presents three key system challenges: model architecture diversity, kernel primitive diversity, and hardware generation and architecture heterogeneity. KernelEvolve is an agentic kernel coding framework that tackles heterogeneity at scale for DLRM. It is designed to take kernel specifications as input and automate the process of kernel generation and optimization for a recommendation model across heterogeneous hardware architectures. KernelEvolve is designed to optimize a wide variety of production recommendation models across generations of Nvidia and AMD GPUs, as well as Meta's AI accelerators. It significantly mitigates the programmability barrier for new AI hardware.

OPENAI TO BUY PINTEREST? STRATEGIC ANALYSIS

OpenAI may acquire Pinterest, a visual search app disguised as a social platform. ChatGPT is missing Pinterest's level of visual efficiency because that is not a core capability of large language models. Pinterest's ability to go from intent to product, or from inspiration to intent to product, will be very important for OpenAI's commerce aspirations. ChatGPT must go visual to create a successful UX and user experience for agentic commerce.
