Frequently asked questions
- Which API host serves the most AI models?
- DeepInfra serves 26 of the 78 models we test, according to OpenRouter's endpoint list.
- Which API host is cheapest?
- Among hosts that compete on at least three models, OpenAI is cheapest most often: the lowest list price for 9 of the 9 models it shares with other hosts.
- Do hosts charge different prices for the same model?
- For 35 of the 47 models served by two or more hosts, list prices differ between hosts. The widest gap is DeepSeek V4 Pro 0813: 11.8× from the cheapest host (Baidu) to the most expensive (Venice), by blended price.
- Is speed measured per host?
- Not yet. Our speed runs went through whichever host OpenRouter routed each request to, so host pages compare price, uptime and limits, not speed.
