OpenRouter provides a unified API interface to access over 400 large language models from 60+ providers, offering better prices and uptime.

OpenRouter acts as a unified interface for accessing a wide range of large language models (LLMs) from various providers through a single API. It supports over 400 models from more than 60 active providers, including major ones like OpenAI and Anthropic. The platform is designed to offer competitive pricing, improved uptime through distributed infrastructure and fallback mechanisms, and minimal latency by running at the edge. The service is fully compatible with the OpenAI SDK, allowing developers to integrate different models by simply updating the base URL and model names. OpenRouter also provides features like custom data policies for organizational control, activity logs, budget controls, and a management API key. Recent additions include consistent web search and fetch capabilities for tool-calling models, and new audio APIs for speech synthesis and transcription across multiple providers.
