Fun (but depressing?) data analysis project from Louis Abraham, showing how repetitive Claude is in the words it chooses when submitting GitHub pull requests. Abraham, in the project’s readme:

GitHub pull request descriptions, grouped by the words they are written with rather than by anything they were told to look for: eight ways of writing, and every description belongs to one of them. One of the eight was 1.0% of the corpus at the start of 2025 and is 45% of it by the middle of 2026.

If you want to get a little more depressed, I’ve been doing deeper reading into AI watermarking research, and one of the admissions in [Google’s white paper on SynthID-Text](https://www.nature.com/articles/s41586-024-08025-4) — the watermarking scheme Anthropic says Claude is going to start using — is that the technique incurs “some reduction to inter-response diversity”. That means different answers to the same prompt become more similar to each other — there’s less variety to watermarked text responses. That’s a load-bearing problem given that Claude clearly already struggles in this regard *before* watermarking its output.
