The most data-rich practitioner account available. Woolf progressed from skepticism to conversion over months of experiments with Claude Opus 4.5/4.6 and OpenAI Codex. Standout result: agent-driven Rust implementations of UMAP ran 2-10x faster than Rust's fast-umap and 9-30x faster than Python's umap. Key insight: agents work best when you have broad domain knowledge to evaluate outputs. minimaxir.com
