Using a dataset of 124 machine learning (ML) systems published between 2009 and 2022,1 I estimate that the cost of compute in US dollars for the final training run of ML systems has grown by 0.49 orders of magnitude (OOM) per year (90% CI: 0.37 to 0.56).2 See Table 1 for more detailed results, indicated by “All systems.”3
By contrast, I estimate that the cost of compute used to train “large-scale” systems since September 2015 (systems that used a relatively large amount of compute) has grown more slowly compared to the full sample, at a rate of 0.2 OOMs/year (90% CI: 0.1 to 0.4 OOMs/year).
