Which open-weight model does
the business work right?

Real spreadsheet edits, PDFs of every kind, reconciliations, VAT returns, inbox triage and fraud checks — scored by code, to the penny, with no LLM judge. Open-weight models only, updated daily as new ones land on OpenRouter.

All categories: the official difficulty-weighted score.

Ranking

Score = difficulty-weighted strict pass. An attempt passes only when every critical check is exactly right (the final balance, the amount to pay, the totals that move when inputs change) and nothing outside the brief was touched. Partial answers score zero. Every scored task is then weighted by 1 − how often the field passes it, so the tasks almost nobody gets right count most — the score has room to grow as models improve. 50 tasks are scored. Reliable = tasks passed on all 3 repeats. Baseline tasks (below) earn nothing; a miss is flagged. The strict pass rate counts every task equally and is shown alongside for auditing. Overlapping 95% ranges are not a real difference.

Score sheet

Per task: share of repeats that strictly passed (0, 33, 67, 100). Shading: ≥95 75–94 50–74 <50. Spread = best minus worst; a low spread means the task is not separating models. 👁 = some content exists only as pixels. ▨ = the input did not fit that model's context window, scored as a failure.
