GPU cloud and inference platform for open-source LLMs — fast, low-cost APIs for Llama, DeepSeek, Qwen, Mistral, plus fine-tuning and dedicated endpoints.
Starting at $0.02/1M tokens
OpenRouter is used as a unified API layer for accessing many LLMs through one OpenAI-compatible interface. Instead of integrating separately with Anthropic, OpenAI, Google, and other model providers, developers can route requests through OpenRouter and use one credit balance across supported models.
OpenRouter can replace direct provider integration for many chat and agent use cases because its API is OpenAI-compatible and the site says the OpenAI SDK works out of the box. Teams with provider-specific requirements should still verify whether the needed features are supported through OpenRouter.
OpenRouter advertises reliability through distributed infrastructure and provider fallback. In practice, this means an application can be configured so that if one provider or model endpoint becomes unavailable, requests can be routed to another compatible option when available.
OpenRouter uses free model access for selected models and pay-as-you-go credits for paid usage. Exact costs depend on the selected model, provider route, input tokens, output tokens, and the live model-level pricing shown by OpenRouter.
OpenRouter highlights custom data policies that let organizations control which models and providers can receive prompts. These controls are relevant for teams that need budget enforcement, provider restrictions, or safer model access across internal applications.
