OpenRouter

OpenRouter provides a single, unified API that allows developers and organizations to access hundreds of large language models (LLMs) and other AI models from over 60 providers. Instead of integrating with each provider separately, users can connect to OpenRouter and route their requests to the best available model based on cost, performance, and reliability.

The platform is fully compatible with the OpenAI SDK, making it easy for developers to get started with just a few lines of code. OpenRouter’s distributed infrastructure ensures high uptime and low latency, automatically falling back to alternative providers if one becomes unavailable. This helps maintain service continuity and keeps costs in check without sacrificing speed.

OpenRouter also offers fine-grained data policies, allowing organizations to control which models and providers handle their data. Users can monitor token usage, compare models, and explore performance metrics across different providers and applications. The platform supports advanced features like prompt caching, structured outputs, tool calling, and multimodal message transforms.

With no subscription required, credits can be used across any model or provider, making OpenRouter a flexible and cost-effective solution for accessing state-of-the-art AI capabilities.
