You can use OpenRouter to connect to hundreds of large language models and multimodal artificial intelligence models through a single standard interface. Instead of managing separate accounts and API keys across multiple AI providers, you buy prepaid credits and route requests to models from Anthropic, OpenAI, Google, and open-source creators. The service automatically falls back to secondary providers if an outage occurs, compares live pricing and latency, and lets you enforce custom data privacy rules to restrict where your prompts travel.
