Utilize the unlimited free GPT-3.5-Turbo API service provided by the login-free ChatGPT Web.

Due to the frequent updates of OpenAI, I have once again created a new version, which is based on DuckDuckGo, and is GPT-3.5-Turbo-0125.

Repo: https://github.com/missuo/FreeDuckDuckGo

Deploy

Node

npm install
node app.js

Docker

docker run -p 3040:3040 ghcr.io/missuo/freegpt35

docker run -p 3040:3040 missuo/freegpt35

Docker Compose

Only FreeGPT35 Service

mkdir freegpt35 && cd freegpt35
wget -O compose.yaml https://raw.githubusercontent.com/missuo/FreeGPT35/main/compose/compose.yaml

mkdir freegpt35 && cd freegpt35
wget -O compose.yaml https://raw.githubusercontent.com/missuo/FreeGPT35/main/compose/compose_with_next_chat.yaml

Request Example

You don't have to pass Authorization, of course, you can also pass any string randomly.

curl http://127.0.0.1:3040/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer any_string_you_like" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [
      {
        "role": "user",
        "content": "Hello!"
      }
    ],
    "stream": true
    }'

Compatibility

You can use it in any app, such as OpenCat, Next-Chat, Lobe-Chat, Bob, etc. Feel free to fill in an API Key with any string, for example, gptyyds.
