> Frontier AI feels like its full of people who are brilliant at making models, but when it comes to scale and practicality, they just leave it to whoever sets up infrastructure to worry about.
The idea that people in 10+ frontier labs (OpenAI, Anthropic, Google, Alibaba, Z.ai, DeepSeek, xAI, Amazon, etc) in a trillion dollars industry are all dumb is frankly, hilarious.
Anthropic's API has two nines availability and Claude Code is a TUI made with React that can regularly consume more than 1GB of RAM, and the codebase is utter slop. They couldn't fix the flickering bug for over a year!
And yet, Fable and Opus are among the best coding models out there (matched only by GPT5.6 Sol).
It's not about the people there being smart or not, it's about their and the company's priorities, resources and what they choose to focus on.
You cannot just "try all possible optimisations". It takes time, effort, and money that could otherwise be spent elsewhere (especially for training, where each training run is especially costly, and optimisations might be promising early on, but cause the final performance of the model to be worse). You need smart people interested in unglamorous work, and if you're swimming in VC money, it's far more straightforward to just throw more GPUs at the problem.
