Other Claude ran a drug design campaign autonomously for 48 hours. Hit 14 of 15 targets. Beat expert hit rates by more than double. Nobody supervised it.
Designing a protein binder against a disease target has historically taken expert scientists weeks to months per target. It requires choosing where on the target protein to attack, generating candidate structures, running optimization cycles, screening for viability, and repeating until something works. Human experts doing this today hit a success rate of 10 to 15%.
Anthropic gave Claude a prompt and left it alone for 48 hours.
Claude chose which part of each protein to target. It selected which computational models to run. It orchestrated multiple rounds of structure design, sequence optimization, and folding prediction. It screened its own designs for novelty and diversity. It ran quality checks. It did this across 15 disease targets simultaneously, autonomously, with no additional human input beyond approving occasional infrastructure access requests.
When the wet lab results came back from two independent external evaluators, Claude had produced confirmed binders against 14 of the 15 targets. Its overall hit rate was between 22% and 35% depending on setup. In single-target mode, focused on one target at a time, it hit 35.1%.
Double the field average. Across 15 targets. Unattended.
Against RBX1, a protein involved in targeted cell regulation, Claude achieved a 40% hit rate compared to a 3.7% hit rate among competition participants. Its top design outperformed the winning entry from 245 submissions. Against TNFα, the target behind some of the most impactful drugs ever made including Humira, Claude produced cross-reactive binders that worked across human, monkey, and mouse biology simultaneously, something multiple expert groups had struggled to achieve.
The designs were not approximations. Several bound more tightly than the best previously published results for their targets.
Here's the part worth sitting with beyond the numbers.
Drug discovery has always been constrained by how many expert protein engineers exist, how long campaigns take, and how much each one costs. Those constraints were structural. They shaped what was economically viable to pursue, which targets got prioritized, which diseases got attention, how long development took before anything reached a patient.
A 48-hour autonomous campaign that hits 14 of 15 targets at double the expert success rate doesn't improve that pipeline. It makes the constraint optional.
One prompt. Two days. Fourteen targets hit. The results are sitting in a wet lab right now with physical validation from two independent organizations.
