Open Source GPT-3 Powered Command Line Interface (CLI) is a powerful tool that can be used to generate text with a prompt length of approximately 840 tokens. The cost of using Text-Davinci-002 for 1K tokens is estimated to be $0.02, which works out to be around $0.017 per command. With some fine-tuning, it is possible to not only improve the response but also reduce the cost per command.
