OpenRouter

What is OpenRouter

OpenRouter is a unified API that gives you access to models from OpenAI, Anthropic, Google, Meta, Mistral, and more. With Fastlane + OpenRouter BYOK, you get smart routing across all of them.

Setup

1. Get an API key from openrouter.ai/keys

2. Add to your settings:

[byok]
openrouter_key = "sk-or-your-key"

3. Restart Fastlane

Available Models

OpenRouter models are prefixed with the provider:

• openai/gpt-4o
• openai/gpt-4o-mini
• anthropic/claude-sonnet-4-20250514
• anthropic/claude-3.5-haiku
• meta-llama/llama-3.3-70b-instruct
• meta-llama/llama-3.1-8b-instruct
• mistralai/mixtral-8x7b-instruct

Why Use OpenRouter

• Single key - One key for dozens of providers
• More models - Access models not available directly
• Automatic fallback - If one provider is down, OpenRouter retries another
• Usage tracking - See all your usage in one dashboard

Pricing

OpenRouter charges per-token on top of the provider’s base price. Check openrouter.ai/models for current rates.
