Add contextual memory. Make it save past messages like below this to a json file, then append it before the new message in the curl request.

{"role": "system", "content": "You are an AI"},
{"role": "user", "content": "Hello!"},
{"role": "assistant", "content": "Hello there!"},
{"role": "system", "content": "You are an AI"},
...
So on...
