Our review
OpenRouter aggregates OpenAI, Anthropic, Google and a sea of open models behind one OpenAI-compatible API: a single key switches any model, billing is unified, routing can optimize for price or speed, and traffic fails over automatically when a provider goes down.
The extra hop adds a little latency and a small fee, and enterprises must do their own compliance review. But for multi-model apps and fast experiments, OpenRouter is close to default infrastructure for developers.
