PHAI Labs Paper Defines Discovery Foundation Models With Seven Coupled Capabilities and GALILEO Case Study

PHAI Labs' Discovery Foundation Models paper (arXiv 2609.15973, Sept 15) argues for a new capability category beyond task-solving agents, defined by seven coupled skills (problem discovery, formulation, representation, hypothesis, intervention, revision, continual improvement) trained via multi-signal RL from scientific feedback. It instantiates the framework as 'Zetema' with dry-lab/wet-lab grounding, and reports a therapeutic-discovery case study called GALILEO that produced a transferable Amphiphilic Balance Grammar. The paper distinguishes DFMs by requiring agents to construct problems and revise representations, not just solve given tasks.
