ESTIMATE (base-model reference; self-hosted open weights, no public tariff): OpenRouter google/gemma-4-31b-it, the reference of the published deck31b and quyet-1-0-large rows, USD 0.09 per 1M input and USD 0.34 per 1M output x this row's own measured tokens. Estimated, not charged
Measured p50 latency: 0.126 s (on-GPU, no network, loopback; not directly comparable with API latency, which we time end to end from our measuring host, network included)
Ranking and cap use: 0.40 s (est. incl. network (2x + 150 ms))
Self-hosted model: measured p50 0.126 s on-GPU, no network (timed on our GPU over loopback). Not directly comparable with API latency, which we time end to end from our measuring host, network included. The ranking and latency cap use the same estimate for every self-hosted row: 2 × measured + 150 ms = 0.40 s. Model authors can ask us to time a hosted endpoint instead (on request).
x2 + 0.15 s (assumption, not measured)
