There’s one more man you are missing that fits better with the Windows piece that is more likely than those two. A man that was obsessed with anonymity (with no real picture of him on the net), an active writer still today, and with the coding and cryptography chops to have actually built it.
Agree. Can really build a strong chain of functionality with this function calling. I have a harder time seeing the use of something like Langchain - seems unnecessary to learn a new bloated API when I can use the powerful tools from the models themselves, and then chain things together myself.
Yes, the 'function calling' naming is unfortunate. It's really structured output that can be fed as input into any functionality elsewhere in your code.
The difference between the structured output of json mode is that the model can choose which set of structured output (matched to various function definitions). Subtle, but pretty cool and powerful.
