About OpenRouter
OpenRouter provides a single interface to access more than 500 AI models from providers such as ChatGPT, Claude, Gemini, and DeepSeek. It lets users route requests to the most suitable model for each task and automatically switches to a fallback model if the primary one fails, helping applications stay online. The platform supports auto-routing to the lowest-cost model and exposes a unified API so developers can integrate multiple models without rewriting their code. Teams can test new models quickly, compare outputs, and optimize costs by selecting cheaper alternatives for non-critical tasks. OpenRouter is aimed at software engineers, data scientists, and teams building AI-powered products who need flexibility and reliability across providers. It is commonly used to prototype with the latest models, run A/B tests between different LLMs, and deploy production applications that require high availability and cost control.
