Most business AI use is the messy middle: multi-step workflows that need a smart enough model at a price a company can afford. It is the most important part of the market today, & it is where the competition is fiercest.Sep 23, 2026· Post
If this is the first of many primitives specialized for production, then harnesses are about to capture a lot more margin.Sep 21, 2026· Post
They also highlight the bifurcating economics of AI: state of the art models for discovery & optimized models for production. We use the largest frontier models to train new models, & the most capable models to architect systems. But once a system is engineered & hardened, running it thousands or millions of times through a workflow benefits from narrower AI.Sep 21, 2026· Post
AI customer retention sits between mobile games and social networks. Frontier models keep the crown for about 41 days, and the price of a given level of intelligence falls roughly 10x per year, giving buyers more leverage every cycle.Jul 13, 2026· Post

AI is fantastic at automating tasks that have verifiable outcomes, which is why we’re seeing amazing strides from coding, mathematical proofs, and workplace productivity is an extension to that.Andrew ChenSep 8, 2026· Post
Since the end of 2025, it has seemed that the era of devs writing code by hand is over at startups and in Big Tech. AI agents work faster and generate more pull requests (PRs) than devs ever did, and the size of those pull requests is also increasing.Gergely OroszSep 8, 2026· Post
