GPT-4 CAN USE TOOLS - NOW THAT'S A BIG DEAL

Summary from the TLDR newsletter

The GPT API was recently updated with a tool called function calling. Function calling allows GPT to call out to external code, databases, or other APIs whenever it needs to. GPT can decide which tools to use and when. This ability makes GPT models significantly more powerful as it helps them overcome many of their limitations. It also makes some open-source projects obsolete. OpenAI's release should remind developers that projects built at the infrastructure layer can be easily obviated by a future OpenAI update.
