Tech Insight: Developing AI models is not that hard

Andreessen Horowitz partner Martin Casado said AI innovation now depends less on genius and more on the ability to assemble data and computing power. He said building AI models may be easier than many think as well-funded teams outside elite backgrounds produce strong models. Casado said the pretraining phase for foundation models is largely over and expects reinforcement learning to drive the next stage, while business models for major AI developers remain uncertain.
