I've been experimenting with LLM autoresearch. I prompted Sol to make difftastic faster without changing output on the test suite, and log everything it tried: https://github.com/Wilfred/difftastic/blob/c6e9c6fed4c71276a8b0e377c92695c3d929dc7f/PERF_RESEARCH_LOG.md It found some interesting performance tweaks, although it's too tolerant of complexity.
