Model's maximum context length exceeded

Unless the commit is a very very very small one (a few lines in a single file), I always get this error:

`Error: (error http 400) ((error (message . This model's maximum context length is 16385 tokens. However, your messages resulted in 27482 tokens. Please reduce the length of the messages.) (type . invalid_request_error) (param . messages) (code . context_length_exceeded)))`
