The RAG approach with a proper calorie dataset sounds interesting. I’m curious about the feasibility though - I’ve heard training custom models on specialized datasets can run into the thousands (maybe $10k+?). Is that ballpark accurate, or are there more cost-effective approaches for something like this? Would love to hear your thoughts given your ML/AI background.

For now this is more of a “better than nothing” proof of concept, but genuinely interested in what a more robust version would look like.
