Cost and measurement conditions
$0.014 per 1,000 decisions (estimated)
v1.5.4 published cost per 1,000 decisions carried (pricing rules unchanged; v1.6 item lengths differ): ESTIMATE: documented hosted-model estimate; reference deepinfra:Qwen/Qwen3.5-4B frozen at the 25 Sep cut-off, already marked deprecated at that cutoff (replaced by Qwen/Qwen3.5-9B); re-score if it changes (I-3). Frozen market reference deepinfra:Qwen/Qwen3.5-4B.
Measured p50 latency: 0.047 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: 0.24 s (est. incl. network (2x + 150 ms))
Self-hosted model: measured p50 0.047 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 = 0.24 s. Model authors can ask us to time a hosted endpoint instead (on request).
x2 + 0.15 s (assumption, not measured)
Current frozen 1500-item pool measured 2026-10-04 by coordinator plan P88 on one evaluator-owned Lium H100. Current staged log verifies evalengine/decision-4b-gguf@08859d1d8307f7b7ea452549e303b7805c35e350; stored GGUF SHA256 f2519bcdc945291974c81a37ff92417b22df27154c9df2564420d08576b907ce. Serial offline loopback-only inference, standard selfhosted x2+0.15 s latency adjustment. Carried published estimate retained.
