OpenRouter
OpenRouter is a multi-model unified access platform that allows developers to access over 400 large language models from over 60 model providers, including GPT-4, Claude, Gemini, Llama, Mistral, DeepSeek, and more, through a single API. The platform is compatible with OpenAI API calls, supports multilingual SDK access, and can configure custom calls with model keys. Developers can flexibly call different models based on the points billing system, and manage quotas, usage logs, and call monitoring in a unified manner. OpenRouter provides automatic routing, model degradation mechanisms, dynamic load balancing, and other capabilities, making it suitable for building highly available, cross-model intelligent agents, AI tools, task processing systems, and other application scenarios, reducing development complexity and improving system elasticity and scalability.
