ChatGPT Helper

This is an extension to quickly query OpenAI's ChatGPT (both GPT-3.5 and GPT-4) from VS Code. A ChatGPT Plus subcription is not required to use this extension.

GPT-3.5, which powers ChatGPT, is a large language model made by OpenAI. The official GPT-3.5 API costs $0.002 / 1K tokens for both prompts and responses, where 1,000 tokens is approximately 750 words, so $1 would buy approximately 375,000 words.

Alternatively, you can opt to use GPT-4, GPT-3.5's successor, which is an even more powerful model. The API is currently invite-only, however you can sign up for the waitlist here. The API is more expensive than GPT-3.5, costing $0.03 / 1K tokens for prompts and $0.06 / 1K tokens for responses, meaning $1 would buy approximately 12,500 words of prompts and 6,250 words of response..

To use this extension, you must provide an OpenAI API token linked to an account with billing set up; costs for using the API are charged directly to your OpenAI account.
