This project converts the API of Anthropic's Claude model to the OpenAI Chat API format.
- ✨ Call Claude API like OpenAI ChatGPT API
- 💦 Support streaming response
- 🐻 Support
claude-instant-1
,claude-2
models - 🌩️ Deploy by Cloudflare Workers or Docker
You can run this project using Cloudflare Workers or Docker:
By using Cloudflare Workers, you don't need a server to deploy this project.
- Create a Cloudflare Worker
- Paste the code in
cloudflare-worker.js
to Cloudflare Worker "Quick Edit" Editor - Save and deploy
- (Optional) Set custom domain for your Cloudflare Worker
The Cloudfalre Workers support 100k requests a day, If you need to call more than that, you can use Docker to deploy as below.
docker run -p 8000:8000 wtzeng/claude-to-chatgpt:latest
docker-compose up
The API will then be available at http:https://localhost:8000. API endpoint: /v1/chat/completions
When you input the model parameter as gpt-3.5-turbo
or gpt-3.5-turbo-0613
, it will be substituted with claude-instant-1
. otherwise, claude-2
will be utilized.
Here are some recommended GUI software that supports this project:
curl http:https://localhost:8000/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $CLAUDE_API_KEY" \
-d '{
"model": "gpt-3.5-turbo",
"messages": [{"role": "user", "content": "Hello!"}]
}'
The Claude Completion API has an endpoint /v1/complete
which takes the following JSON request:
{
"prompt": "\n\nHuman: Hello, AI.\n\nAssistant: ",
"model": "claude-instant-1",
"max_tokens_to_sample": 100,
"temperature": 1,
"stream": true
}
And returns JSON with choices and completions.
The OpenAI Chat API has a similar /v1/chat/completions
endpoint which takes:
{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "user",
"content": "Hello, AI."
}
],
"max_tokens": 100,
"temperature": 1,
"stream": true
}
And returns JSON with a response string.
This project converts between these two APIs, get completions from the Claude model and formatting them as OpenAI Chat responses.
