## Quote — verbatim

> GPUs are the fuel for AI. The need for GPUs is doubling every 3.5 months as these LLM models get more advanced... GPT-3.5 is 175 billion parameters and GPT-4 is going to be a trillion parameters — that means you need that much of compute.

## Context — site annotation, not spoken

Quantifying the AI compute curve just before GPT-4's release; adds that OpenAI was proposing ~$250,000/year for a dedicated ChatGPT instance and "90% of the cost goes to GPU" ([00:34:50](https://www.youtube.com/watch?v=328BxcY4ec4&t=2090s)).
