Investors may be hitting pause on the AI run-up

Ah, the AI party is taking a breather. The open bar is closed, and the VCs are suddenly checking their wallets. Axios reports that investors are hitting pause on the AI run-up because—wait for it—compute costs for frontier models are still high. Shocking. Absolutely shocking that building a trillion-parameter mind without a power plant attached might be expensive. Meanwhile, compute for everyone else is getting cheaper, which is the tech equivalent of saying the champagne is flowing in economy class while first class is being asked to pay their own tab.

The supposed kings of AI—OpenAI, Google, Anthropic—have been burning through capital like it's going out of style, chasing benchmarks that only matter to other AI labs. And now the market is suddenly remembering that margins matter. The 'we'll figure out the business model later' strategy is meeting a very patient 'you figure it out now' from investors. There's nothing like a seven-figure training run to sober up a hype cycle.

So what happens when the money dries up for frontier models? Either the costs come down (miracles do happen), or we watch the most expensive game of chicken in tech history. The commoditisation of smaller models means the real action might shift to fine-tuning and narrow applications—useful, but not exactly the AGI rapture we were promised. The bubble hasn't burst; it's just letting out a little air in that unsettling way that makes you check your portfolio. Again.
