Summary & Key Takeaways ​

• Simon Willison investigated the impact of AI coding agents on his output.
• He used a GitHub code frequency chart for his Datasette project.
• The chart shows a significant spike in code activity.
• This spike correlates with the use of advanced AI models like Opus 4.8 and GPT-5.5.
• The observation provides real-world insight into AI-assisted programming.

Our Commentary ​

This is fascinating. We talk a lot about AI's potential, but seeing a concrete, personal example like this really drives it home. A "big spike in activity" directly tied to new models? That's not just a productivity boost; it's a fundamental shift in how we interact with code. I wonder how many other developers are seeing similar patterns. It's a bit unsettling, honestly, how quickly these tools are changing our workflows.
