EP27: Medical Foundation Models - with Tanishq Abraham (Sophont.AI)

Tanishq Abraham, CEO and co-founder of Sophont.ai, joins us to talk about building foundation models specifically for medicine.

Sophont is trying to be something like an OpenAI or Anthropic but for healthcare  - training models across pathology, neuroimaging, and clinical text, to eventually fuse them into one multimodal system. The surprising part: their pathology model trained on 12,000 public slides performs on par with models trained on millions of private ones. Data quality beats data quantity.

We talk about what actually excites Tanishq, which is not replacing doctors, but finding things doctors can't see. AI predicting gene mutations from a tissue slide, or cardiovascular risk from an eye scan.

We also talk about the regulation and how the picture is less scary than people assume. Text-based clinical decision support can ship without FDA approval. Pharma partnerships offer near-term impact. The five-to-ten-year timeline people fear is really about drug discovery, not all of medical AI.

Takeaways:

• The real promise of medical AI is finding hidden signals in existing data, not just automating doctors
• Small, curated public datasets can rival massive private ones
• Multimodal fusion is the goal, but you need strong individual encoders first
• AI research itself might get automated sooner than biology or chemistry
• FDA regulation has more flexibility than most people think
