@karlprosser @YashHustle_22 Disagree. There is no “wiping the floor”. Benchmarks are the 2026 version of AI slop.

[Dan McCoy, MD @docdano]

@YashHustle_22 Agree. Accurate statement against the anti-Claude slop.

@DutchRojas You might check this out. It would be great for you to join the discussion. https://t.co/JIsDqmZMP0

You have probably been out of the game for a bit so easy to understand. Check out Serif Health that uses ML to parse TiC files into natural language readable info. Some of the biggest users are independent physician groups. Insurers as a group are the least interested. They know the prices.

[Dan McCoy, MD @docdano]

@DutchRojas Great point! Check out Serif Health for great transparency data. The providers make it hard to find but Serif uses ML to make is easy to understand.

@peduarte There is no standard anymore than there is one Rust or one Typescript.

@petergyang There is no standard anymore than there is one OS.

@mark_k This is just a great question and something we talked about this week on a podcast: what will be the physician liability if THEY DON'T utilize AI tools in the future?

[Dan McCoy, MD @docdano]

Brand meds sell at list price, then the supply chain adds markups. Same pattern with hospitals - they set prices, insurers pass them through. Both are cost problems at the source. Both have middle-chain markups.

The difference: you're disrupting pharma distribution with Cost Plus. Who's doing that for hospital prices? Price transparency data shows 300-500% variation for the same procedure in the same city. That's the bigger dollar problem for employers. I'd love it if you would expand CostPlus to hospitals!

new ignition episode

target's pregnancy algorithm was a 12-year preview of how healthcare AI is going to work for the rest of our lives

and almost nobody is framing it correctly

on the podcast:

[Dan McCoy, MD @docdano]

genuinely cannot stop thinking about this one

your smartwatch can detect cognitive decline 6-12 months before you can. atrial fibrillation days early. depression weeks ahead of clinical scoring.

the science is settled

the actually hard question is who gets to see the model output

wrote it up:

@TheAhmadOsman It all demands on your depreciation schedule whether you “make money” or not. And, what are you using the inference for. So much gripe about Anthropic pricing on here, but the delta between client pricing and local LM cost is huge. That is why we do it. Better margins.

[Dan McCoy, MD @docdano]

target's pregnancy prediction algorithm from 2012 needed 25 features to know a teenager was pregnant before her dad did

your phone broadcasts 200-400 health-adjacent signals an hour now

a modern version needs maybe 6

this is the healthcare AI story nobody's telling correctly
