datasette code-frequency chart on GitHub. Out of curiosity I decided to see if I could find a useful illustration of the impact of coding agents and Opus 4.5 class models on my own output. The best I've found so far is this GitHub chart of frequency of code changes to my Datasette open source project:

Screenshot of a GitHub "Code frequency" bar chart, subtitled "Additions and deletions per week", showing green addition bars and red deletion bars per week from 2018 through 2026, with a y-axis labeled Frequency ranging from -20k to 30k. Activity comes in sporadic bursts: the largest spike is 37,022 additions with -9,528 deletions in 2026, followed by 14,638 additions with -6,584 deletions in late 2025, 15,998 additions in early 2018, and a standout deletion spike of -10,658 in mid-2020, with quieter periods of smaller weekly changes in between.

The big spike in activity at the end aligns with Opus 4.8, GPT-5.5, Fable 5 and GPT-5.6 Sol.
