Came across this new paper on using self-improving LLM agents to automate the quant research loop, from factor discovery to model development. The system keeps validated results from previous experiments and uses them to guide the next round of research. The researchers built in sealed sandboxes so the AI cannot cheat on test results.

The reported results are pretty strong (net positive for 5 years, 2.5 Sharpe for US stocks) although I’m more curious about the methodology and how robust this is out of sample.

For those doing quant research, do you think this kind of recursive research loop could actually become useful in practice, or are there some obvious failure modes I’m missing?
