- A developer, inspired by Nick Cammarata's interpretability essay "Neural Networks Are Already Clean", turned its ideas into speedups for pretraining without backpropagation. Still a work in progress, with a claimed 2.3x speedup.
- Quoter astridwilde argues "mech interp is just capabilities research by another name", hinting interpretability work is being used to boost capabilities rather than only for safety understanding.
