Epoch AI tracked quarterly production of AI accelerators across the major chip designers and found total AI compute growing about 3.3x a year since 2022, a seven-month doubling (X). It turns the 15 million H100-equivalents stock of two days earlier into a rate, and pairs with the 1.9% of GDP capex figure as the dollar side of the same curve. The newsletter treats the clock as the driver of everything downstream, reading the same day’s Erdős #729 solution as a function of compute rather than insight; the recursive-self-improvement storyline later sets a capability clock beside this hardware one when the UK’s AI Security Institute measures a 4.5-month capability doubling.
Development
Global AI compute doubles every seven months
The newsletter's base clock speed of civilization: the measured growth rate of the substrate on which every self-improvement gain in the corpus compounds, stated as a doubling time rather than a stock.
Claim
Epoch AI reported global AI compute capacity is doubling every seven months, a 3.3x annual compounding rate.
Reported metric: 3.3x/year
Reporting date: (not necessarily the event date)
