Switching from OpenRouter

OpenRouter alternative.
More modalities, lower fee, same catalog.

OpenRouter is a popular text-model router with ~300 text LLMs. AIgateway covers the same frontier text models plus image, video, audio, voice, music, and embeddings — under one schema, one key, and a lower platform fee.

Migration

One-line diff.

Change the base URL and the key. Every other line of your integration stays the same.

Before — OpenRouter
from openai import OpenAI

client = OpenAI(
    base_url="https://openrouter.ai/api/v1",
    api_key="sk-or-...",
)

r = client.chat.completions.create(
    model="openai/gpt-5.4",
    messages=[{"role": "user", "content": "Hello"}],
)
After — AIgateway
from openai import OpenAI

client = OpenAI(
    base_url="https://api.aigateway.sh/v1",
    api_key="sk-aig-...",
)

r = client.chat.completions.create(
    model="openai/gpt-5.4",
    messages=[{"role": "user", "content": "Hello"}],
)
Why switch

What AIgateway ships that OpenRouter doesn't.

WINS
  • Every modality, not just text — image, video, voice, audio, music, embeddings under the same schema.
  • 5% flat platform fee at credit top-up — no per-call fees, no variable markup.
  • Sub-account API for scoped end-user keys with spend caps (OpenRouter has none).
  • Eval-driven routing: grade candidate models on your data, bind the winner to an alias.
  • Replay + shadow A/B on any logged request to safely test new models.
HONEST
What OpenRouter does better, per their public docs.
  • OpenRouter has a longer tail of community text models; we curate to what ships reliably.
