OpenAI doesn't lack investment capital. What they still don't have is a good source of high quality clinical data. And this isn't just a matter of buying access to deidentified patient charts from some large health system. Most clinical data quality is kind of crap so using it directly for model training produces garbage output. You need an extensive cleansing and normalization pipeline designed by human clinicians who understand the data at a deep level.

That’s true but they have a massive shortage of clinical data. Doctor patient confidentiality is a thing.
