GPT-5 autonomously runs 36,000 experiments in Ginkgo's cloud lab, cutting protein-synthesis cost 40%
OpenAI and Ginkgo Bioworks reported that GPT-5, in a closed loop with Ginkgo's automated cloud lab, tested over 36,000 cell-free protein synthesis reaction compositions on 580 plates over six rounds. It cut the cost of producing sfGFP by 40% ($422/g vs $698/g), with reagent cost 57% lower, reaching a new state of the art within three rounds.
Key facts
- 6 closed-loop rounds; 36,000+ compositions; 580 plates
- Cost $422/g vs $698/g of sfGFP (−40%); reagent cost −57%
- The optimised mix is now sold commercially by Ginkgo
- bioRxiv preprint (Feb 2026); not yet peer-reviewed

What happened
GPT-5 designed each round of experiments, Ginkgo's robots ran them, and the results fed back to the model.
Why it matters
It is a concrete, economically meaningful result from an LLM driving a physical lab end-to-end.
