OpenAI utilizes managed databases on Azure, employing a classic PostgreSQL primary-replication architecture without sharding.

AT AMAZON, SOME CODERS SAY THEIR JOBS HAVE BEGUN TO RESEMBLE WAREHOUSE WORK

As AI spreads through the labor force, many white-collar workers say their work is becoming more routine, less thoughtful, and much faster-paced. Companies seem to be persuaded that AI can increase productivity. Teams are getting smaller, but they're being expected to output the same amount of work by using AI. Managers say that AI can relieve employees of tedious tasks and enable them to perform more interesting work, but for inexperienced workers, the change resembles the shift from artisanal work to factory work in the 19th and 20th centuries.

ASK HN: GO DEEP INTO AI/LLMS OR JUST USE THEM AS TOOLS? (HACKER NEWS THREAD)

Large language models are becoming commodities. Many people use them, but few people are developing them from scratch. Developing large language models involves a lot of hardcore computer science and math - people can use them without having to know any of the internals. While it might be helpful to understand some of the internals and math, it's probably best to stick to learning how to get good at using these models and integrating what they do into agentic systems.
