 In 2018, the processing power was increased again to 8.4 petaflops,  The agency also tested a potential replacement model with different mechanics, the flow-following, finite-volume icosahedral model (FIM), in the early 2010s; it abandoned that model around 2016 after it did not show substantial improvement over the GFS.In 2019, as a result of the recent tenfold increase in computing power, an upgrade to the GFS model is planned that will increase its horizontal resolution to 9 km and 128 layers out to 16 days, compared to the current run of 13 km and 64 layers out to 10 days.As of the 12z run on 19 July 2017, the GFS model has been upgraded.
