Chronology
Timeline of frontier model releases
Every model in the dataset, plotted by its release date. Each dot is one model release; its size encodes the total inference spend that model has accumulated in this dataset (log scale), and its color encodes the lab. Vendor lanes are stacked vertically so multiple releases close in time are visually separated.
