About OpenRouter

OpenRouter aggregates models from multiple providers into a single API. They offer both free and paid models with transparent per-token pricing. Through Antbase, OpenRouter serves as one of many providers — ANT routes to OpenRouter when it offers the best combination of model availability and cost.

How to Use OpenRouter on Antbase

All OpenRouter models are available through Antbase's unified OpenAI-compatible API. You can either route directly to a specific OpenRouter model or let ANT's intelligent router automatically select the best model for your task.

from openai import OpenAI

client = OpenAI(
    base_url="https://antbase.ai/v1",
    api_key="your-ant-api-key",
)

# Let ANT auto-route (may use OpenRouter if optimal)
response = client.chat.completions.create(
    model="ant:auto",
    messages=[{"role": "user", "content": "Hello!"}],
)

# Or route directly to a OpenRouter model
response = client.chat.completions.create(
    model="openrouter/free-llama",
    messages=[{"role": "user", "content": "Hello!"}],
)
