Wait. 150 is one third of the USDA answer, and 375 is half of the USDA answer? What is the USDA answer?
This equation is beyond my paygrade!
Edit: I asked our GPT3.5 bot to solve this, and it hallucinated "pulling up the USDA database" ; complete with a "(a few moments later...)" message before giving me 160 calories as the USDA answer.
I asked the same bot (identical prompts) with GPT-4-Turbo enabled and it went through "step by step" to say the correct answer is 461 calories because 1/3 cup uncooked is 1 cup cooked, so 1 rice cooker cup (160g) = 3/4 cup uncooked, so 2.25 cooked * 205 = 461 cal.
Is that the right answer? If so, 375 seems far from "half"
The database gives 716 calories for 1 cup uncooked rice. So, 537 calories for 3/4 cup. It was a mistake to say 375 was half of 537, my intention was to point out that it's not close.

I don't have access to GPT-4 but your results are interesting. I don't understand why it's trying to approximate the yield of the uncooked rice after cooking before giving a calorie estimate. From my testing it doesn't do this for other ingredients like raw chicken.
It seems to be more accurate when giving calorie estimates for a list of ingredients instead of a single ingredient. For example, in a recipe that includes "boneless skinless chicken thighs (1 lb, raw)" ChatGPT gives "about 880 calories" as the answer. But in a new prompt if you ask it only about the chicken and nothing else, it gives "between 1100 and 1300 calories." The USDA database shows 144 calories per 100 grams, so 653 calories per pound. The first answer by ChatGPT is much more accurate.
I have no idea why this is the case, and I bet this would be easy for a researcher to demonstrate if true. Alas, I don't have API access.
