I really only tried out the Wolfram one for a few prompts to see if it worked. I also have been compiling a list of the ChatGPT plugins (in the store and unverified) which hopefully will become a public post later this week. Per Logan this would not be a good idea for a valid reason. As I don’t know if the reason should be made public will not give the details.
My real goal with them was noted here when I first learned of them. Also considering doing one for Lambda Calculus, think reduction strategies. Hopefully it will give me some much needed insight into the inner workings of how LLMs work, I would not be surprised if some of the reduction strategies never work and can not be learned with a transformer.
