Despite continuing to bet big on A.I. startups and chip programs, the founders of the venture capital firm Andreessen Horowitz say they’ve noticed a drop off in A.I. model capability improvements in recent years. Two years ago, OpenAI’s GPT-3.5 model was “way ahead of everybody else’s,” said Marc Andreessen, who co-founded Andreessen Horowitz alongside Ben Horowitz in 2009, on a podcast released yesterday (Nov. 5). “Sitting here today, there’s six that are on par with that. They’re sort of hitting the same ceiling on capabilities,” he added.
