Microsoft Opens a Biology AI That Learns Genes, Proteins and Cells Together
Microsoft Research introduced Quine, an experimental artificial intelligence system for biology, on Sept. 29, 2026, and opened applications for a first cohort of outside scientists to use it. What is new is the shape: one model trained jointly across genetic sequence, protein structure and function, cell state and microscope images, not a set of specialist models wired together.
In its announcement, the company says the system is meant to rank and narrow options before anyone spends time in the lab, with the model sitting inside a harness that connects it to scientific tools, the published literature and the researchers using it. Microsoft calls Quine research technology only, not for clinical or medical use, and says its outputs may be incomplete or inaccurate and need review by qualified researchers.
Microsoft's worked example is pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer. Working with researchers at the Broad Institute of MIT and Harvard, the company says it used Quine to rank thousands of compounds by their predicted ability to push tumor cells from one state into another, and that in its own wet-lab assays the highest-ranked compounds produced the largest shifts in the intended direction. Microsoft puts the whole exercise, from a wide field to a short list for the bench, at one weekend. These are the company's own figures: no paper, preprint or benchmark was published alongside the announcement, and no outside group has tested any of it.
The company also reports a result it says it did not expect. Several compounds moved cells toward a third state rather than either of the two it was tracking. Microsoft says the model predicted that, the lab bore it out, and pancreatic tumor cells may occupy a wider range of states than a two-way split.
Access stays narrow for now. Microsoft says availability is limited to the Quine Fellows program, whose first round of applications is open, and to selected research collaborations. The company says it expects to widen access later through its Microsoft Discovery product.
