Google DeepMind says Gemini 4 Argon designed five lab-verified serine esterases in hours

Google DeepMind says Gemini 4 Argon compressed enzyme engineering into a matter of hours and designed five serine esterases that were verified in the lab.

The company reports these results from zero-shot tests of Argon on protein engineering workflows conducted over several weeks. The claim comes from a DeepMind post on X, which does not name the enzymes' target reactions or give performance measurements.
