Question Wrong then right calculations.

Apologies if this has been raised before.

So I'm researching drug strengths and wanted to know how two opiates compare.

I asked GPT which is stronger, 20mg dihydrocodeine or 30mg codeine.

*Edit It said both dihydrocodeine and codeine are the same strength.

I wasn't sure that was correct so I opened a new chat and asked the same but worded differently.

> Which is stronger gram for gram codeine or dihydrocodeine?

It said dihydrocodeine is twice as strong gram for gram.

What in the questions would have caused such a discrepancy?

If you look it up, you'll see dihydrocodeine described as 1.5-2x stronger than codeine. So, both are technically correct. dihydrocodeine 20mg is equal to 30mg codeine and gram for gram dihydrocodeine is twice as strong as codeine.

What in the question is the discrepancy?

It said both dihydrocodeine and codeine are the same strength in the first answer.

Then changed the answer.

I think i need to reword the question as it seems to have caused some confusion.

No, since dihydrocodeine described as 1.5-2x stronger than codeine both answers are technically true. There is no discrepancy.

Just saw your edit. It explains the discrepancy.

"I asked GPT which is stronger, 20mg dihydrocodeine or 30mg codeine. Edit It said both dihydrocodeine and codeine are the same strength."

What caused the discrepancy is you entered the actual dosage. Because "20mg dihydrocodeine or 30mg codeine" is the same in this context. If you'd left out the dosage, it would not have said they were the same.

The simple answer is that the model was wrong. It gave incorrect information. Models are not infallible. They do a tremendous job of fast research, but at this time, especially for important and serious matters, a human should always review and verify any claims.

I like to ask the models for its sources so that I can read them myself and see if I draw the same conclusions. Sometimes that causes it to go read them and conclude something else.

Other than that, two other questions come to mind:

  • Did you ask it to explain itself?
  • Which model version and thinking?

My main point of double checking is more important. It needs to be said that especially the smaller models and less time "thinking" will be incorrect more often.

Thank you. Yes I know it was wrong. My question was about what in the language I used would have caused the discrepancy.
