Does openai has access to data when we use tools or functions

[d1pankarmedhi]

When we use functions/tools for agents, does openai have access to the data output from one of the functions?
Is it something like, the output of the first function getting passed on to the second function without the knowledge of openai OR is it that, openai knows about the data and decides which function to call based on the output data?
How does it work?

After a tool is executed, it's response is sent to OpenAI in the form of a FunctionMessage. Without this response, the model running on OpenAI side wouldn't be able to act as an agent (i.e., take multiple steps based on previous tool results).

Okay, so openai has access to the output of the 1st tool/functions, and it decides which function/tool to call next. Then, the output of 1st is passed as the input to the second function. This is how it works on a high level, right?

That's right
