Core Features
Unified API
Access all major LLMs through a single, OpenAI-compatible interface, simplifying integration and reducing vendor lock-in.
High Availability
Distributed infrastructure with automatic fallback to alternative providers ensures reliable uptime and minimal service disruption.
Edge Performance
OpenRouter runs at the edge, reducing latency between users and inference for fast response times.
Custom Data Policies
Fine-grained data policies allow you to control which models and providers handle your prompts, enhancing privacy and security.
Prompt Caching
Reduce costs by caching repeated prompts; cache reads cost 0.1x to 0.5x of fresh input when sticky routing is enabled.
Auto-routing
Automatically route requests to the best model or provider based on performance, cost, or availability.
Activity Logs & Export
Track and export detailed activity logs for monitoring usage, costs, and compliance.
Classifiers
Define taxonomies and automatically tag each generation by department, task type, or agent complexity for analytics.
Transcription API
Send base64 audio to /api/v1/audio/transcriptions and receive JSON text with usage data using the same API key.
