Monroe: A Molecular Foundation Model for In-Context Probabilistic Inference

Scale plus a prior-fitted model for in-context prediction is a sensible combination for data-starved drug discovery tasks, and the pairwise statistical comparison framework is a good methodological choice that most molecular ML papers skip. This is squarely for computational chemistry and drug discovery teams evaluating foundation models for lead optimization, not a general AI signal. Worth benchmarking against your existing MFM if you're doing bioassay prediction work.

AI in drug discovery – what it is, where we stand and the path forward

Drug discovery has been one of AI's most hyped verticals for a decade, and honest stock-taking pieces like this are useful precisely because they cut through vendor claims from Insilico, Recursion, and others. If the piece is skeptical about near-term clinical wins, that's a signal for investors to recalibrate timelines on biotech AI valuations rather than a reason to abandon the thesis. Worth a read for anyone with capital in this vertical, less urgent for pure software builders.
