 A proxy server that lets you use Anthropic clients with Gemini or OpenAI models via LiteLLM. 🌉
 
-
 ![Anthropic API Proxy](pic.png)
 
 ## Quick Start ⚡
 
 ### Prerequisites
 
-- OpenAI API key 🔑
-- Google AI Studio (Gemini) API key (if using Google provider) 🔑
-- [uv](https://github.com/astral-sh/uv) installed.
+-   OpenAI API key 🔑
+-   Google AI Studio (Gemini) API key (if using Google provider) 🔑
+-   [uv](https://github.com/astral-sh/uv) installed.
 
 ### Setup 🛠️
 
 1. **Clone this repository**:
-   ```bash
-   git clone https://github.com/1rgs/claude-code-openai.git
-   cd claude-code-openai
-   ```
+
+    ```bash
+    git clone https://github.com/1rgs/claude-code-openai.git
+    cd claude-code-openai
+    ```
 
 2. **Install uv** (if you haven't already):
-   ```bash
-   curl -LsSf https://astral.sh/uv/install.sh | sh
-   ```
-   *(`uv` will handle dependencies based on `pyproject.toml` when you run the server)*
+
+    ```bash
+    curl -LsSf https://astral.sh/uv/install.sh | sh
+    ```
+
+    _(`uv` will handle dependencies based on `pyproject.toml` when you run the server)_
 
 3. **Configure Environment Variables**:
    Copy the example environment file:
-   ```bash
-   cp .env.example .env
-   ```
-   Edit `.env` and fill in your API keys and model configurations:
-
-   *   `ANTHROPIC_API_KEY`: (Optional) Needed only if proxying *to* Anthropic models.
-   *   `OPENAI_API_KEY`: Your OpenAI API key (Required if using the default OpenAI preference or as fallback).
-   *   `GEMINI_API_KEY`: Your Google AI Studio (Gemini) API key (Required if PREFERRED_PROVIDER=google).
-   *   `PREFERRED_PROVIDER` (Optional): Set to `openai` (default) or `google`. This determines the primary backend for mapping `haiku`/`sonnet`.
-   *   `BIG_MODEL` (Optional): The model to map `sonnet` requests to. Defaults to `gpt-4.1` (if `PREFERRED_PROVIDER=openai`) or `gemini-2.5-pro-preview-03-25`.
-   *   `SMALL_MODEL` (Optional): The model to map `haiku` requests to. Defaults to `gpt-4.1-mini` (if `PREFERRED_PROVIDER=openai`) or `gemini-2.0-flash`.
-
-   **Mapping Logic:**
-   - If `PREFERRED_PROVIDER=openai` (default), `haiku`/`sonnet` map to `SMALL_MODEL`/`BIG_MODEL` prefixed with `openai/`.
-   - If `PREFERRED_PROVIDER=google`, `haiku`/`sonnet` map to `SMALL_MODEL`/`BIG_MODEL` prefixed with `gemini/` *if* those models are in the server's known `GEMINI_MODELS` list (otherwise falls back to OpenAI mapping).
+
+    ```bash
+    cp .env.example .env
+    ```
+
+    Edit `.env` and fill in your API keys and model configurations:
+
+    - `ANTHROPIC_API_KEY`: (Optional) Needed only if proxying _to_ Anthropic models.
+    - `OPENAI_API_KEY`: Your OpenAI API key (Required if using the default OpenAI preference or as fallback).
+    - `GEMINI_API_KEY`: Your Google AI Studio (Gemini) API key (Required if PREFERRED_PROVIDER=google).
+    - `PREFERRED_PROVIDER` (Optional): Set to `openai` (default) or `google`. This determines the primary backend for mapping `haiku`/`sonnet`.
+    - `BIG_MODEL` (Optional): The model to map `sonnet` requests to. Defaults to `gpt-4.1` (if `PREFERRED_PROVIDER=openai`) or `gemini-2.5-pro-preview-03-25`.
+    - `SMALL_MODEL` (Optional): The model to map `haiku` requests to. Defaults to `gpt-4.1-mini` (if `PREFERRED_PROVIDER=openai`) or `gemini-2.0-flash`.
+
+    **Mapping Logic:**
+
+    - If `PREFERRED_PROVIDER=openai` (default), `haiku`/`sonnet` map to `SMALL_MODEL`/`BIG_MODEL` prefixed with `openai/`.
+    - If `PREFERRED_PROVIDER=google`, `haiku`/`sonnet` map to `SMALL_MODEL`/`BIG_MODEL` prefixed with `gemini/` _if_ those models are in the server's known `GEMINI_MODELS` list (otherwise falls back to OpenAI mapping).
 
 4. **Run the server**:
-   ```bash
-   uv run uvicorn server:app --host 0.0.0.0 --port 8082 --reload
-   ```
-   *(`--reload` is optional, for development)*
+    ```bash
+    uv run uvicorn server:app --host 0.0.0.0 --port 8082 --reload
+    ```
+    _(`--reload` is optional, for development)_
 
 ### Using with Claude Code 🎮
 
 1. **Install Claude Code** (if you haven't already):
-   ```bash
-   npm install -g @anthropic-ai/claude-code
-   ```
+
+    ```bash
+    npm install -g @anthropic-ai/claude-code
+    ```
 
 2. **Connect to your proxy**:
-   ```bash
-   ANTHROPIC_BASE_URL=http://localhost:8082 claude
-   ```
+
+    ```bash
+    ANTHROPIC_BASE_URL=http://localhost:8082 claude
+    ```
 
 3. **That's it!** Your Claude Code client will now use the configured backend models (defaulting to Gemini) through the proxy. 🎯
 
 ## Model Mapping 🗺️
 
 The proxy automatically maps Claude models to either OpenAI or Gemini models based on the configured model:
 
-| Claude Model | Default Mapping | When BIG_MODEL/SMALL_MODEL is a Gemini model |
-|--------------|--------------|---------------------------|
-| haiku | openai/gpt-4o-mini | gemini/[model-name] |
-| sonnet | openai/gpt-4o | gemini/[model-name] |
+| Claude Model | Default Mapping    | When BIG_MODEL/SMALL_MODEL is a Gemini model |
+| ------------ | ------------------ | -------------------------------------------- |
+| haiku        | openai/gpt-4o-mini | gemini/[model-name]                          |
+| sonnet       | openai/gpt-4o      | gemini/[model-name]                          |
 
 ### Supported Models
 
 #### OpenAI Models
+
 The following OpenAI models are supported with automatic `openai/` prefix handling:
-- o3-mini
-- o1
-- o1-mini
-- o1-pro
-- gpt-4.5-preview
-- gpt-4o
-- gpt-4o-audio-preview
-- chatgpt-4o-latest
-- gpt-4o-mini
-- gpt-4o-mini-audio-preview
-- gpt-4.1
-- gpt-4.1-mini
+
+-   o3-mini
+-   o1
+-   o1-mini
+-   o1-pro
+-   gpt-4.5-preview
+-   gpt-4o
+-   gpt-4o-audio-preview
+-   chatgpt-4o-latest
+-   gpt-4o-mini
+-   gpt-4o-mini-audio-preview
+-   gpt-4.1
+-   gpt-4.1-mini
 
 #### Gemini Models
+
 The following Gemini models are supported with automatic `gemini/` prefix handling:
-- gemini-2.5-pro-preview-03-25
-- gemini-2.0-flash
+
+-   gemini-2.5-pro-preview-03-25
+-   gemini-2.0-flash
 
 ### Model Prefix Handling
+
 The proxy automatically adds the appropriate prefix to model names:
-- OpenAI models get the `openai/` prefix 
-- Gemini models get the `gemini/` prefix
-- The BIG_MODEL and SMALL_MODEL will get the appropriate prefix based on whether they're in the OpenAI or Gemini model lists
+
+-   OpenAI models get the `openai/` prefix
+-   Gemini models get the `gemini/` prefix
+-   The BIG_MODEL and SMALL_MODEL will get the appropriate prefix based on whether they're in the OpenAI or Gemini model lists
 
 For example:
-- `gpt-4o` becomes `openai/gpt-4o`
-- `gemini-2.5-pro-preview-03-25` becomes `gemini/gemini-2.5-pro-preview-03-25`
-- When BIG_MODEL is set to a Gemini model, Claude Sonnet will map to `gemini/[model-name]`
+
+-   `gpt-4o` becomes `openai/gpt-4o`
+-   `gemini-2.5-pro-preview-03-25` becomes `gemini/gemini-2.5-pro-preview-03-25`
+-   When BIG_MODEL is set to a Gemini model, Claude Sonnet will map to `gemini/[model-name]`
 
 ### Customizing Model Mapping
 
 Control the mapping using environment variables in your `.env` file or directly:
 
 **Example 1: Default (Use OpenAI)**
 No changes needed in `.env` beyond API keys, or ensure:
