If you're looking for "Hot Dog/Not A Hotdog" type (i.e., heavily bounded) answers from LLMs, make certain to at least consider (or better still benchmark) traditional AI and machine learning approaches against LLMs. The traditional approach is almost certainly less computationally expensive and might work better for your problem than an LLM. I recall hearing stories from people on a popular podcast, that they benchmarked and went with the traditional approach because it was more accurate, deterministic, and cheaper. Many had always wanted to try traditional AI/ML, but only got the go ahead recently to add AI to their project from management because of the AI/LLM hype. They were surprised to find that when they benchmarked, the traditional approaches outperformed LLMs both in terms of accuracy and cost. Don't get fixated on LLMs to the point of ignoring older tools that might do a better job.
