X.8 Cost Active
Each result reports tokens per item and, where a price table is available, the converted cost per item. Recorded as a required report field.
Evidence: none. No benchmark card lists this capability yet. No level is issued: methodology 0.1.0 sets no level thresholds.

Definition in detail
Cost decides whether a capability can be used in practice. Results without cost cannot be compared.
Inputs a task gives
- Usage counters from each run
- A price table, where one is available
Artifact required
Required fields in the result record: tokens per item and, with a price table, converted cost per item.
How it is graded
Reported, not graded. Where token counts or a dated price table exist, the result record carries them and the site checks them against the run records; missing cost fields are shown as "—", never as zero.
In scope
- All tokens consumed by the run, including sub-agents and tool-side model calls
- Converted cost per item when a price table is available
Out of scope
- Score stability - X.7
- Step counts used to compare tool revisions - graded under B.5
Typical failures
Expected failure patterns; not measured rates.
- Counting output tokens only
- Omitting tokens used by sub-agents
- Converting cost with an outdated price table
