Since GPT-3.5 and GPT-4 APIs are available many companies and start-ups have implemented them into their products. Now developers have started to do it the other way around. They build systems around GPT-4 to enable it to search, use APIs, execute code, and interact with itself. Examples are HuggingGPT or AutoGPT. They are based on works like Toolformer or this result. Even Microsoft itself started to build LLM-Augmenter around GPT-4 to improve its performance.

I talked about this development in my post on how to get from GPT-4 to proto-AGI. I still think that this is the way to a general assistant even though I am not sure if GPT-4 is already capable enough or if we need another small improvement.
