Just kidding, I wrote the readme... or did I?

$ gpt

This Bash script uses the OpenAI API to generate a response to a user-specified query using the GPT-3 language model. The response is appended to a specified context file, which contains the history of messages and responses.

Requirements

To use this script, you will need:

• Bash (version 4 or later)
• curl
• jq
• pandoc (optional pretty printing to terminal)
• elinks (optional retty printing to terminal)

You will also need an OpenAI API key, which can be obtained from the OpenAI website.

Installation

1. Copy paste the script in a $PATH directory.
2. Make the script executable with chmod +x gpt.
3. Add export OPENAI_KEY="your-api-key" to your .bashrc.

You can now run the script.

Note: If you do not wish to export your OpenAI API key, you can include it directly in the script by replacing $OPENAI_KEY with your actual API key.

Usage

To run the script, use the following command:

gpt                   # Opens the context file for editing.
gpt Hellp gpt         # Uses the arguments as input.
stdin | gpt           # Uses the stdin as user input.
stdin | gpt Hello gpt # Uses stdin + arguments as input.

It's important to know that you can configure gpt using the environment variables. I create gpt aliases for different tasks. Here is a list of those variables and their default values.

OPENAI_KEY="${OPENAI_KEY:?OPENAI_KEY is not set}"
OPENAI_MODEL="${OPENAI_MODEL:-gpt-3.5-turbo}"
OPENAI_CONTEXT="${OPENAI_CONTEXT:-/tmp/gpt.$WINDOWID}"
OPENAI_PROMPT="${OPENAI_PROMPT:-/tmp/gpt.$WINDOWID.prompt}"
OPENAI_TOKENS="${OPENAI_TOKENS:-4096}"

$WINDOWID is unique for every terminal you open. This allows you to spawn a new terminal and start with a clean slate.

alias programmer-gpt='OPENAI_PROMPT="$HOME/programmer.prompt" gpt'
alias git-gpt='OPENAI_PROMPT="$HOME/git.prompt" gpt'

Thanks @mountaineerbr, I assume you meant wrapper; warper sounds way cooler though. I might borrow an idea or two from your script, but this gist is meant to stay a simple warper.

@bas081 OK, I understand. That is worthwhile to have your own chatgpt script, at least you know exactly what is going on!
If I may point it out, perhaps setting temperature, and/or presence/frequency penalty is in order to unlobotomise the bot a little more..
The guys at The Linux Link Tech Show use the word "warp" as a verb for describing what some programmes do, not as agentive noun which is grammatically wrong, but you get the gist! Cheers!
