ChatGPT-to-API

Create a fake API using ChatGPT's website

IMPORTANT

You will not get free support for this repository. This was made for my own personal use and documentation will continue to be limited as I don't really need documentation. You will find more detailed documentation in the Chinese docs by a contributor.

API endpoint: http://127.0.0.1:8080/v1/chat/completions.

Setup

Authentication

After 2024-04-02, accouts.txt is optional because no need authentication for gpt-3.5.

Access token and PUID(only for PLUS account) retrieval has been automated by OpenAIAuth with account email & password.

accounts.txt - A list of accounts separated by new line

Format:

email:password
...

All authenticated access tokens and PUID will store in access_tokens.json

Auto renew access tokens and PUID after 1 day

Caution! please use unblocked ip for authentication, first login to https://chatgpt.com/ to check ip availability if you can.

HAR file pool

Currently logged in account, using the GPT-4 model and most GPT-3.5 models, you need to configure a HAR file (file with .har suffix) to complete captcha verification.

Use a chromium-based browser (Chrome, Edge) to open the browser developer tools (F12), switch to the Network tab, and check the preserve log option.
Log in to https://chatgpt.com/, create a new chat and select the GPT-4 model, enter any text, switch to the GPT-3.5 model, and enter any text.
Click the Export HAR button under the Network tab to export the file chatgpt.com.har and place it in the harPool folder of the same level as this program.

API Authentication (Optional)

Custom API keys for this fake API, just like OpenAI api
