Cost and measurement conditions

$0.043 per 1,000 decisions (estimated)

ESTIMATE, v1.5-M2 base-model reference rule. Launchables publishes a list price for Myles-G 31B (launchables.ai/licensing, fetched 21 Oct 2026, saved copy sha256 ad4736d5...): GBP 0.005 per million input tokens, output free; that is USD 0.0066734 per million input tokens at the ECB reference rate of 20 Oct 2026 (GBP 1 = USD 1.33468), prices exclude VAT. Under the method, the base-model reference price applies as an ESTIMATE for this vendor-hosted row, as for attest-31b-v1.0: base model google/gemma-4-31B-it through the frozen pricing_v15 module (sha256 1f4d1f7b1ce97ab27b938043444b9c2757e4a9dbecc799a803122588401f5bf1) reference() -> google/gemma-4-31b-it on OpenRouter, USD 0.09 per million input tokens, USD 0.34 per million output tokens. The vendor list price is shown for information and is not used for the Cost axis. Applied to this row's own provider-reported tokens (907,107 input and 1,500 output tokens over all 1,500 items; 697,619 input and 1,485 output tokens over the 1,485 items of the common cost basis; the 15 truncated items count for no row's cost). Estimated, not a vendor bill and not a quote. 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 in full).

p50 latency: 0.4 s

none (API)

Paid public fast-lane order 46550a0f. Vendor-hosted Launchables API (api.launchables.ai, model `myles-g-31b`, TypeSafe-compatible endpoint), through the unchanged TypeSafe adapter; latency measured from Sandy (Germany) over the official per-item latency subset without API adjustment; one non-item warm-up request preceded the scored loop and is excluded. Full S1200+P300 draw of v1.6-regular-20261012 through the unchanged run_api_full_v161.py; the full-set exposure gate logged all 1,200 sealed items to provider `launchables` (no proxy) before the first request. All 1,500 of 1,500 requests answered with HTTP 200 and the served model was `myles-g-31b` on every row; native probabilities on all three question types. Run with the customer's own API key; hosting implementation and deployed weights were not independently inspected.
