Higher is better. Each point prices a typical request of the model (~80k input / 1k output) at the recorded market rates, against today’s cheapest OpenRouter endpoint for the same request, using input and output rates only on both sides; OpenRouter history is not recorded. Negative values mean above the OpenRouter reference. Dashed lines show current references and the gateway estimate. Recorded market prices exclude the routing fee; gaps stay visible. In + out = 1M input + 1M output tokens.
