Can Language Models Self‑Optimize? Inside the STOP Framework

Researchers introduce the Self‑Taught Optimizer (STOP), a scaffolding‑based framework that lets large language models iteratively improve their own code without altering model weights, demonstrating superior performance on tasks like LPN, exploring diverse strategies such as beam search and genetic algorithms, while also highlighting security risks like sandbox bypass and reward hacking.
