LLM-designed antibodies hit 38/80 binders in lab tests, 85% success on RAGE

A team built opendde-harness, a workflow that uses LLM reasoning to design antibodies and then validated the designs experimentally: 80 synthesized designs across three targets produced 38 experimentally detected binders.

Success rates by target–format cohort:

Notably, CXCR4 is a 7-transmembrane protein notoriously hard to target with synthetic antibodies due to its dynamic conformations, yet 10 designs still bound. A commenter who co-discovered CXCR4 as an HIV co-receptor 30 years ago called it a super impactful BioAI model. Example workflow: ask the LLM to design a VHH against CRLF2, verifying target and epitope, keeping the framework fixed, and designing CDRs with a visible plan.
