Model's maximum context length exceeded when building agent

[kingcharlezz]

I'm trying to use the GPT model to interact with the Google Calendar API, but I'm receiving the following error message:

"This model's maximum context length is 4097 tokens. However, your messages resulted in 4392 tokens. Please reduce the length of the messages."

Could someone please help me find a way to avoid exceeding the model's maximum context length, or suggest alternative approaches to achieve the same functionality without encountering this issue? Any help would be greatly appreciated.
