Backend storage costs of AI inference are underestimated
What happened
On 22 October 2026, MIT Technology Review reported that the hidden storage costs of AI inference are underestimated. The report cites internal WD measurements: for an 8-second AI video, the user ultimately receives a 3.97MB 720p file, but the associated data left behind on the backend exceeds 500MB, 130 times the size of the output file. The report therefore points out that substantial backend storage overhead continues after inference ends. So far this is the only report on the matter, with no follow-up developments or differing accounts.

- MIT Technology Review · AIAI’s hidden storage bill: What inference leaves behind
Ask most executives to picture the cost of AI and they’ll likely see GPUs—racks of accelerators with gigawatts of power—and a waitlist for silicon. But that picture leaves something out: Data storage costs. What happens to data after a model responds?
