Auto Router

The Auto Router model from OpenRouter is a sophisticated meta-model designed to optimize your AI interactions. Instead of manually choosing an AI, Auto Router analyzes your prompt and dynamically selects the most suitable model from a vast array of options, including cutting-edge models like OpenAI's GPT-5 series, Anthropic's Claude 3.5 Haiku, Google's Gemini 2.5 Pro, and many others. This ensures you consistently receive the best possible output for your specific needs. This intelligent routing is powered by Not Diamond technology, providing a seamless and efficient experience. You can track which model was used for each request in your activity log. With a generous 2000K token context window and 4K token max output, Auto Router is ideal for complex and lengthy conversations. It's available for free, offering exceptional value and access to premium AI capabilities without direct cost per token.
