🔧 Quick Start: Access All Models with One API

Instead of managing separate API keys for each provider, you can use an API gateway to access all models through a single OpenAI-compatible endpoint.

Example with Python (OpenAI SDK):

from openai import OpenAI

# Works with any OpenAI-compatible gateway
client = OpenAI(
    api_key="your-api-key",
    base_url="https://your-gateway.com/v1"  
)

# Switch models by just changing the model name
models = [
    "claude-sonnet-4-20250514",
    "gpt-4.1",
    "gemini-2.5-pro-preview-05-06",
    "deepseek-chat",
]

for model in models:
    response = client.chat.completions.create(
        model=model,
        messages=[{"role": "user", "content": "Explain quicksort in 3 sentences"}],
    )
    print(f"{model}: {response.choices[0].message.content[:100]}...")

Popular API gateways: Crazyrouter, OpenRouter, AIHubMix

📈 Key Trends — May 2026
