Why does DeepSeek's low training cost signal a shift toward AI commoditization?

Question

Accepted Answer

_Cheaper AI training costs mean models become commodities, not defensible assets._

> DeepSeek-V3's last training run cost just $5.576 million. Compare this to the $100 million that GPT-4 supposedly cost. That is 18 times smaller. AI technology is rapidly becoming more accessible everywhere at lower costs.
