MemGPT uses function calling to do memory management. With [OpenAI's ChatCompletion API](https://platform.openai.com/docs/api-reference/chat/), you can pass in a function schema in the `functions` keyword arg, and the API response will include a `function_call` field that includes the function name and the function arguments (generated JSON). How this works under the hood is your `functions` keyword is combined with the `messages` and `system` to form one big string input to the transformer, and the output of the transformer is parsed to extract the JSON function call.
In the future, more open LLMs and LLM servers (that can host OpenAI-compatable ChatCompletion endpoints) may start including parsing code to do this automatically as standard practice. However, in the meantime, when you see a model that says it supports “function calling”, like Airoboros, it doesn't mean that you can just load Airoboros into a ChatCompletion-compatable endpoint like FastChat, and then use the same OpenAI API call and it'll just work.

1. When a model page says it supports function calling, they probably mean that the model was finetuned on some function call data (not that you can just use ChatCompletion with functions out-of-the-box). Remember, LLMs are just string-in-string-out, so there are many ways to format the function call data. E.g. Airoboros formats the function schema in YAML style (see https://huggingface.co/jondurbin/airoboros-l2-70b-3.1.2#agentfunction-calling) and the output is in JSON style. To get this to work behind a ChatCompletion API, you still have to do the parsing from functions keyword arg (containing the schema) to the model's expected schema style in the prompt (YAML for Airoboros), and you have to run some code to extract the function call (JSON for Airoboros) and package it cleanly as a function_call field in the response.
