LiteLLM Proxy with OpenAI SDK

OpenAI

First, add this to your litellm proxy config.yaml:

OpenAI Proxy Configuration

model_list:
  - model_name: gpt-image-1
    litellm_params:
      model: gpt-image-1
      api_key: os.environ/OPENAI_API_KEY

Start the LiteLLM proxy server:

Start LiteLLM Proxy Server

litellm --config /path/to/config.yaml

# RUNNING on http://0.0.0.0:4000

Basic Image Edit via Proxy

OpenAI Proxy Image Edit

from openai import OpenAI

# Initialize client with your proxy URL
client = OpenAI(
    base_url="http://localhost:4000",  # Your proxy URL
    api_key="your-api-key"             # Your proxy API key
)

# Edit an image
response = client.images.edit(
    model="gpt-image-1",
    image=open("original_image.png", "rb"),
    prompt="Add a red hat to the person in the image",
    n=1,
    size="1024x1024"
)

print(response)

</TabItem>

<TabItem value="gemini" label="Gemini">

1. Add the Gemini image edit model to your `config.yaml`:
```yaml showLineNumbers title="Gemini Proxy Configuration"
model_list:
  - model_name: gemini-image-edit
    litellm_params:
      model: gemini/gemini-2.5-flash-image
      api_key: os.environ/GEMINI_API_KEY

2. Start the LiteLLM proxy server:

Start LiteLLM Proxy Server

litellm --config /path/to/config.yaml

3. Make an image edit request (Gemini responses are base64-only):

Gemini Proxy Image Edit

curl -X POST "http://0.0.0.0:4000/v1/images/edits" \
  -H "Authorization: Bearer <YOUR-LITELLM-KEY>" \
  -F "model=gemini-image-edit" \
  -F "image=@original_image.png" \
  -F "prompt=Add a warm golden-hour glow to the scene" \
  -F "size=1024x1024"
