# Claims of Closed-Loop Self-Improvement in Enzyme Engineering Outrun the Published Evidence

Automated protein platforms that propose mutations, synthesise and assay them, and retrain on the results are real and documented since 2024. Reviews report that they operate with substantial human involvement, not autonomously.

A widely shared post this week describes closed-loop recursive self-improvement in biology: a model predicts which mutations improve an enzyme, an automated laboratory synthesises, expresses and assays them, and the model retrains on the re…
