What it answers that a model cannot answer alone

A language model answers from training data that is months old and does arithmetic from memory. This server returns the current figure with its source. In the words of its README, it knows these things that your model does not.

  1. Which drugs FDA lists as in shortage today. Shortages start and end every week, and openFDA refreshes the list daily.
  2. Package level detail. Each listing is one NDC from one company, with its own availability and update date.
  3. Whether a shortage was resolved or the product is being discontinued, with the date and the FDA note.
