Chai Discovery develops AI models that predict and reprogram biochemical molecule interactions. Chai’s goal is to shorten the drug development timeline so that potential new medicines enter first-in-human studies and reach the market quicker. It can design molecules that have needed properties and tackle challenging targets that have been out of reach. The team has already used its flagship model Chai 2 to develop monoclonal antibodies aimed against tough-to-drug targets, and (accoring to the company) the new designs have properties similar to known antibody drugs.
