重磅:昂贵的新证据表明规模扩张并非万能

BREAKING: Expensive new evidence that scaling is not all you need

AI 导读

两项耗资巨大的AI实验相继失败,为"规模扩张并非实现突破的唯一路径"提供了新的佐证。这些结果表明,单纯依靠增加算力、数据和模型参数的传统Scaling策略可能已触及瓶颈,行业需要探索新的技术范式,而非一味追求规模扩张。

Two more colossally expensive experiments have failed

Remember the good old days a few years ago when almost everybody thought that the royal road to AGI ws just spending more money on compute and data?

That hypothesis continues to go badly, as expensive experiments from two of the world’s wealthiest men have just shown.

On the hand, it’s become clear that Mark Zuckerberg’s latest model at Meta is good but not great, and not what he was hoping for.

And in the very same week, Elon Musk has conceded that for all the gigantic models xAI has built, xAI was ”not built right first time around”. Instead most of the founders are gone, and Musk has said that the company “is being rebuilt from the foundations up”.1

So much for pure scaling2

Two of the most expensive scientific experiments in history. Sooo much money down the drain.

In my 2020 article, The Next Decade in AI, I foresaw all this, and urged the field to start focusing on world (cognitive) models and neurosymbolic AI. Now, maybe, we can finally move on to those projects?

So much time, money, and energy was lost chasing hype.

Elon’s concession also fits well with the theory offered here on Feb 3 that SpaceX’s acquisition of xAI at $250 billion was a thinly disguised bailout. You don’t pay $250 billion for a company that was built wrong from the foundations.

Musk could —literally— have saved tens of billions of dollars, if he had asked me….

Discussion about this post

Starting to feel glad they cocked it up. Can you imagine what these guys would have done with it if they’d got to AGI? Best they go broke before they attain that sort of power :)

"Musk could —literally— have saved tens of billions of dollars, if he had asked me" - or me! :-)
