datasette code-frequency chart on GitHub
Simon Willison Simon Willison
Simon Willison examined his Datasette open source project's GitHub code-frequency chart to measure the impact of AI coding assistants on his productivity. A notable spike in commit frequency appeared in the most recent period, coinciding with the release of models including Opus 4.8, GPT-5.5, Fable 5, and GPT-5.6 Sol. The increased activity suggests AI coding tools have accelerated his development pace on the project.
Why it matters
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: The big spike in activity at the end aligns with Opus 4.8, GPT-5.5, Fable 5 and GPT-5.6 Sol.
