Default model deprecated

[raghavkarol]

The default model text-davinci-003 has been deprecated. This causes codegpt command to fail. Running openapi with debug-mode shows the error message:

[ENCODED]: {"model":"text-davinci-003","prompt":"What is the following?\n\n(cl-defun openai-completion ( prompt callback\n\n","max_tokens":2000,"temperature":1.0}
