A Node.js Netlify Function based port of [jtsang4/claude-to-chatgpt](https://github.com/jtsang4/claude-to-chatgpt)'s cloudflare-worker.js. This project converts the API of Anthropic's Claude model to the OpenAI Chat API format.
Netlify Function calls offer _slightly_ more resources than Cloudflare Workers and may be more performant in some use cases. _However, Netlify Functions do not support streaming._
A PHP port, designed to deploy on DigitalOcean App Platform, is available [samestrin/claude-to-chatgpt-digitalocean](https://github.com/samestrin/claude-to-chatgpt-digitalocean) here.
## Dependencies
- **Node.js**: The script runs in a Node.js environment.
- **node-fetch**: A Node.js module used for making HTTP requests to external APIs.
## Features
- **API Compatibility**: Enables Claude model integration by mimicking the OpenAI ChatGPT API structure.
- **Model Flexibility**: Supports various configurations of Claude models including claude-instant-1 and claude-2.
- **Performance Optimization**: Utilizes the enhanced capabilities of Netlify Functions for improved performance over alternatives like Cloudflare Workers.
## Deploy to Netlify
Click this button to deploy the project to your Netlify account:
[](https://app.netlify.com/start/deploy?repository=https://github.com/samestrin/claude-to-chatgpt-netlify)
## **Endpoints**
### **Chat Completion**
**Endpoint:** `/v1/chat/completions`
**Method:** POST
Simulate ChatGPT-like interaction by sending a message to the Claude model.
#### **Parameters**
- `model`: The OpenAI model (e.g., 'gpt-3.5-turbo') or Claude model (e.g.,'claude-instant-1') to use. (OpenAI models are automatically mapped to Claude models.)
- `messages`: An array of message objects where each message has a `role` ('user' or 'assistant') and `content`.
#### **Example Usage**
Use a tool like Postman or curl to make a request:
```bash
curl -X POST http://localhost:[PORT]/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{
"model": "claude-instant-1",
"messages": [
{"role": "user", "content": "Hello, how are you?"}
]
}'
```
The server will process the request and return the model's response in JSON format.
### **Model Information**
**Endpoint:** `/v1/models`
**Method:** GET
Retrieve information about the available models.
#### **Example Usage**
Use curl to make a request:
```bash
curl http://localhost:[PORT]/v1/models
```
The server will return a list of available models and their details in JSON format.
### **CORS Pre-flight Request**
**Endpoint:** `/`
**Method:** OPTIONS
Handle pre-flight requests for CORS (Cross-Origin Resource Sharing). This endpoint provides necessary headers in response to pre-flight checks performed by browsers to ensure that the server accepts requests from allowed origins.
#### **Example Usage**
This is typically used by browsers automatically before sending actual requests, but you can manually test CORS settings using curl:
```bash
curl -X OPTIONS http://localhost:[PORT]/ \
-H "Access-Control-Request-Method: POST" \
-H "Origin: http://example.com"
```
The server responds with appropriate CORS headers such as Access-Control-Allow-Origin.
## Testing Your Netlify Deployment Locally
Start your Netlify dev server using the command:
```
netlify dev
```
then use the following curl command to test your deployment:
```
curl -X POST http://localhost:8888/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: YOUR_CLAUDE_API_KEY" \
-d '{"model": "gpt-3.5-turbo", "messages": [{"role": "user", "content": "Hello, how are you?"}]}'
```
## Options
This application can be configured with various options through environment variables:
- **CLAUDE_API_KEY**: API key for accessing the Claude API.
- **CLAUDE_BASE_URL**: URL endpoint for the Claude API; defaults to "https://api.anthropic.com" if not set.
- **CLAUDE_MAX_TOKENS**: Maximum tokens that can be processed in a request; defaults to 100000 if not set.
- **CLAUDE_MAX_REQUEST_SIZE_BYTES**: Maximum size of the request payload in bytes; defaults to 1048576 (1MB) if not set.
