I did find this Info.

GPT-3.5 Turbo models can understand and generate natural language or code and have been optimized for chat using the Chat Completions API but work well for non-chat tasks as well.
As of July 2024, use gpt-4o-mini in place of GPT-3.5 Turbo, as it is cheaper, more capable, multimodal, and just as fast. GPT-3.5 Turbo is still available for use in the API.

I'm currently using 4.1 for most of my database work. It's faster than 5, and for most of what I do (usually just spelling, grammar, and formatting), it works just fine. As far as things I do from a database with automation, I use 5 if I'm working with the web-based version.

4.1  Or  4.1 mini  Or  4.1 nano

I just use regular 4.1. I've found that Mini and Nano are faster, but the responses they give aren't as good, and I'll wait a few seconds longer for a better reply. Mini and Nano are okay if all you're doing is a basic spelling and grammar check, but anything with context, no.

Thanks Richard.
I'm just going to be using it in the Access AL Builder for now.

Yeah, I'd stick with regular 4.1.
