Frequently Asked Questions

Is OpenRouter worth the extra cost?

For most teams: yes at early stage. OpenRouter provides: single billing account, unified API across 100+ models, automatic failover when a provider is down, and model routing. The 5-15% markup buys engineering time and reliability. At >$5,000/month direct API cost, consider switching to direct APIs for the models you use most.

Which providers is OpenRouter most cost-effective for?

OpenRouter's markup is lowest on open-weight models (Llama, Mistral, DeepSeek) where they're running dedicated infrastructure. For OpenAI and Anthropic models, OpenRouter adds a clear markup — evaluate if the unified API is worth the cost at your volume.
