Our Verdict
OpenRouter does one thing exceptionally well: it collapses dozens of vendor relationships into a single OpenAI-compatible API and one key. Switching models means changing a string, automatic failovers keep you running, and per-request price transparency makes cost comparison almost too easy. The trade-offs are structural: a routing layer sits between you and providers, adding slight latency, and per-model prices can shift without notice. Anyone building on more than one model — or who wants the freedom to swap tomorrow — should default to it; teams committed to a single vendor gain less.
