[1/3] Happy to share that our paper "MapPFN: Learning Causal Perturbation Maps in Context" has been accepted at NeurIPS 2026! 🎉 TL;DR: We frame perturbation prediction as an in-context learning problem given a set of interventional experiments.

[1/6] How can we build virtual cell foundation models that adapt to unseen biological contexts? Meet MapPFN, the first prior-data fitted network (PFN) for perturbation prediction. Meta-learned from a synthetic biological prior, it adapts at inference via in-context learning. 🧵
