Ask HN: How can ChatGPT serve 700M users when I can't run one GPT-4 locally?

Sam said yesterday that chatgpt handles ~700M weekly users. Meanwhile, I can't even run a single GPT-4-class model locally without insane VRAM or painfully slow speeds.<p>Sure, they have huge GPU clusters, but there must be more going on - model optimizations, sharding, custom hardware, clever load balancing, etc.<p>What engineering tricks make this possible at such massive scale while keeping latency low?<p>Curious to hear insights from people who've built large-scale ML systems.

Food, housing, & health care costs are a source of major stress for many people
