Per-outcome cost of two fixed reference workloads across the routes a buyer actually has (derived-instruments decision of record, 2026-07-24). Cost is per task, not per token — and the v1.0 limitation is disclosed on every surface where a value displays (acceptance condition of the 2026-07-24 decision).

| Frontier set | claude-sonnet-5 · gpt-5.6-terra · gemini-3.1-pro, each with ordered fallbacks; median of the three workload costs; each model at its cheapest route across providers/sources that day |
| Open-weight set | deepseek v4 family · kimi k2/k3 · qwen 3.5 flagship open-weight sizes · llama 3.3-70b, across all providers; minimum workload cost |
| Self-host throughput assumption | v1.0 (2026-07-24): 700 output tok/s per H100 for 70B-class open weights (cited range 600–800); 60% sustained utilisation, input processing absorbed; minimum deployment 4× H100; nodes = ceil(out_tokens_day / (700 × 0.60 × 86,400 × 4)); $/day = max(nodes,1) × 4 × 24 × price_hrAny change to these numbers is a methodology version bump, not an edit. |

| Assessment close | 18:30 UTC — the scheduled daily cycle anchorfrom the day's token_pricing rows plus the GAP legs |
| Submission cut-off | n/a — no submitted inputs |
| Publication time | With the daily print (masthead: 04:30 AEST) — on the briefing, /instruments, the daily report, /api/print/<date> (permanent) and MCP. |
| Data hierarchy applied | Published per-token list prices from provider price cards (offers, tier 2 — executable at the posted rate; no transactions) and the GAP legs (tier-2 bookable asks). Judgment: none (arithmetic). |
| Accelerator class / contract basis / region | n/a on the API paths; the self-host paths inherit GAP-H100's SXM-class basis |
A path prints only when at least one qualifying route exists in the day's token_pricing rows; the index prints when its cheapest path exists. No formal floor is specified.

| 2026-08-14 | — | rwi_s_selfhost_reserved and rwi_l_selfhost_reserved cease printing from 2026-08-22 — their input is the suspended reserved leg. RWI-S / RWI-L cheapest-path indices are unaffected: the cheapest path was the open-API leg on every print of both. | docs/methodology-notices/2026-08-14-instrument-actions.md §6 |
