Yes there are metabolic changes in the mother herself during pregnancy but that's not why it's hard to research. The main fear is that drugs will cross the placenta and affect the growing fetus, or similarly be transmitted through breast milk to an infant. Very young humans are uniquely vulnerable to disruption in their growth that can cause life-long problems.
Maybe not due to attention, but it is certainly possible for chat content to get leaked into other conversations due to bugs in the stack, and in fact it has happened before.
"We took ChatGPT offline earlier this week due to a bug in an open-source library which allowed some users to see titles from another active user’s chat history. It’s also possible that the first message of a newly-created conversation was visible in someone else’s chat history if both users were active around the same time."
You are probably right about this particular LaTeX issue though.
In my case I had hundreds of invoices in a not-very-consistent PDF format which I had contemporaneously tracked in spreadsheets. After data extraction (pdftotext + OpenAI API), I cross-checked against the spreadsheets, and for any discrepancies I reviewed the original PDFs and old bank statements.
The main issue I had was it was surprisingly hard to get the model to consistently strip commas from dollar values, which broke the csv output I asked for. I gave up on prompt engineering it to perfection, and just looped around it with a regex check.
Otherwise, accuracy was extremely good and it surfaced a few errors in my spreadsheets over the years.
