# Claude-on-OpenAI Proxy
|
|
|
|
🚀 **Use Claude Code with OpenAI Models** 🚀
|
|
|
|
A proxy server that lets you use Claude Code with OpenAI models like GPT-4o.
|
|
|
|
## Why Use This?
|
|
|
|
- 🧠 **Leverage Claude Code with more models**: Use Claude Code's powerful coding interface but with OpenAI's more affordable models
|
|
- ⚡ **No code changes needed**: Your Claude clients work without modification
|
|
- 🔄 **Transparent model swapping**: Claude requests are automatically routed to OpenAI equivalents
|
|
|
|
## Quick Start
|
|
|
|
### Prerequisites
|
|
|
|
- OpenAI API key
|
|
|
|
### Setup
|
|
|
|
1. **Clone this repository**:
|
|
```bash
|
|
git clone https://github.com/1rgs/claude-code-openai.git
|
|
cd claude-code-openai
|
|
```
|
|
|
|
2. **Install UV**:
|
|
```bash
|
|
curl -LsSf https://astral.sh/uv/install.sh | sh
|
|
```
|
|
|
|
3. **Configure your API keys**:
|
|
Create a `.env` file with:
|
|
```
|
|
OPENAI_API_KEY=your-openai-key
|
|
```
|
|
|
|
4. **Start the proxy server**:
|
|
```bash
|
|
uv run uvicorn server:app --host 0.0.0.0 --port 8082
|
|
```
|
|
|
|
### Using with Claude Code
|
|
|
|
1. **Install Claude Code** (if you haven't already):
|
|
```bash
|
|
npm install -g @anthropic-ai/claude-code
|
|
```
|
|
|
|
2. **Connect to your proxy**:
|
|
```bash
|
|
ANTHROPIC_BASE_URL=http://localhost:8082 DISABLE_PROMPT_CACHING=1 claude
|
|
```
|
|
|
|
3. **That's it!** Your Claude Code client will now use OpenAI models through the proxy.
|
|
|
|
## Model Mapping
|
|
|
|
The proxy automatically maps Claude models to OpenAI models:
|
|
|
|
| Claude Model | OpenAI Model |
|
|
|--------------|--------------|
|
|
| haiku | gpt-4o-mini |
|
|
| sonnet | o3-mini |
|
|
|
|
|
|
You can customize these mappings in `server.py` by editing the `validate_model` function.
|
|
|
|
## How It Works
|
|
|
|
This proxy works by:
|
|
|
|
1. **Receiving requests** in Anthropic's API format
|
|
2. **Translating** the requests to OpenAI format via LiteLLM
|
|
3. **Sending** the translated request to OpenAI
|
|
4. **Converting** the response back to Anthropic format
|
|
5. **Returning** the formatted response to the client
|
|
|
|
The proxy handles both streaming and non-streaming responses, maintaining compatibility with all Claude clients.
