Cost and measurement conditions

$0.044 per 1,000 decisions (estimated)

ESTIMATE, v1.5-M2 base-model reference rule: vendor-hosted API, customer list price USD 0.048/M input and USD 0.00/M output effective 2026-10-11 has been in force fewer than 30 days. Base model google/gemma-4-31b-it reference on OpenRouter USD 0.09/M input / USD 0.34/M output, snapshot fetched 2026-10-12T17:55:05Z (SHA-256 81eae2f3f94bf299c8d4499260f842c357b7a869ce82dfa1741ad6a89cf57014), same base-model estimate precedent as metask_jev_rain_31b_trained. Applied to measured response usage; failed HTTP 500 usage/billing may be unreported. No output generation; reported output tokens 0. Estimated, not a vendor bill. COMMON COST BASIS (v1.6.30): cost per 1,000 decisions is computed on the common 1,485 items of this draw, leaving out the 15 very long items (at least 76,358 input tokens as counted by the rows that answered them). They are the 15 items the Jev reference refused with max_tokens_exceeded, which the other rows that did not answer them refused or failed on; their tokens count for no row, whether the row refused or answered them, and a refused item still counts as a wrong answer for Intelligence. This row: USD 0.043889 per 1,000 decisions (0.679x the official cost cap USD 0.064595), against USD 0.043450 over all 1,500 items (v1.6.29).

p50 latency: 0.1 s

none (API)

Paid public fast-lane order 07d13315. Vendor-hosted attest.engineering /v1/systemone API; latency measured from Sandy (Germany), using the official per-item latency subset without API adjustment. Full S1200+P300 draw, not API A300 supplement; no API equating. 15 of 1,500 requests returned HTTP 500 after 8 retry invocations and are scored as wrong in the full denominator. Public model documentation declares frozen google/gemma-4-31B-it @842da3794eaa0b77d5f08bae87a17459d91ff475, unmodified bf16, no adapter or quantization; single forward pass reading option-label logits, no generated tokens, one fitted temperature (value not documented). Hosting implementation and deployed weights were not independently inspected. Hosted API access is not an open-weights release by the vendor; base weights are under the Gemma 4 licence.
