| # Cost Per Task |
|
|
| Dollars per verified result, not tokens per second. |
|
|
| ## What it measures |
|
|
| Cost, retries, turns, and tokens required for deterministic back-office task success. |
|
|
| Category: `agents`. Status: `alpha`. |
|
|
| ## How to run |
|
|
| ```console |
| $ npx benchmark-cost-per-task list |
| $ npx benchmark-cost-per-task run --model <model-id> --provider openrouter |
| $ npx benchmark-cost-per-task score results.json |
| ``` |
|
|
| `--provider mock` runs the whole benchmark offline with no keys. Real models run |
| through OpenRouter (`OPENROUTER_API_KEY`) or any OpenAI-compatible base URL |
| (`OPENAI_BASE_URL`, `OPENAI_API_KEY`). |
|
|
| ## Data fields |
|
|
| `data/tasks.jsonl` holds 30 tasks, one JSON object per line |
| (kinds: 30 episode). |
|
|
| | field | type | |
| |---|---| |
| | `id` | string | |
| | `kind` | string | |
| | `prompt` | string | |
| | `input` | object | |
| | `expected` | object | |
| | `metadata` | object | |
|

| ## Provenance |

|
| # Cost Per Task provenance |
|
|
| This file is generated from the benchmark definition. |

| - How to get it: Run `node scripts/gen-tasks.mjs --seed 20261015 --split public` from the repository root. |
| - Contamination notes: The public tasks and generator are visible. Use `--split hidden` with an unpublished seed for final evaluations. |
| - Refresh: Generate and review a new public seed every six months. |

| - How to get it: Run `node scripts/fetch-prices.mjs`; no API key is required. |
| - Contamination notes: Factual pricing metadata, not evaluation content; OpenRouter states no separate data licence for the endpoint. |
| - Refresh: Refresh before releases and at least monthly; retain git history for audits. |

|
| ## Grader |
|
|
| Deterministic replay followed by exact virtual file-system and CRM state verification. |
|
|
| ## Limitations |
|
|
| This dataset contains only the public task split (30 tasks). |
| Hidden evaluation splits use a private seed and are deliberately not part of |
| this dataset. Source kinds: live-feed, synthetic. These are evaluation prompts |
| for the `benchmark-cost-per-task` benchmark, not training data; scoring requires the package's |
| deterministic grader. See PROVENANCE.md for contamination notes. |
