Cozy Peptide — Demo video

Cozy Peptide is an AI designer for Live Biotherapeutic Products: name a disease, get a novel therapeutic peptide — screened for safety, matched to the microbial factory that will produce it, and compiled to a DNA order a real lab can build. The bottleneck in living medicines isn't the biology, it's the payload: designing the right peptide is slow, expert-only guesswork. Cozy Peptide boosts it with Meta's Muse Spark models, which mine the scientific literature, draft candidates across multiple scaffolds, and revise them against safety, chassis-compatibility, and biocontainment checks. Every decision is logged in an audit ledger. A Lab Guide then closes the loop, walking through DNA and lab orders, to assay results that feed the next design.
