How this task was evaluated
Results are ordered by this task's published score. API runs use one prompt and one completion; agent runs use a coding harness with tools and iteration. Inspect the execution method when comparing results.
Objective scores use the benchmark's execution checks. Judge scores use a vision panel's fixed rubric; the published score leaves out a model's own family. Missing values are labelled rather than treated as zero.
Read the brief
This is a benchmarking hypothetical, not tax advice. Figures and public-holiday dates are as at FY2025-26 (Australia). You are acting as the bookkeeper for a cafe registered in New South Wales (NSW). This is a SCRIPTED MULTI-TURN run for one quarter. You will be asked a sequence of questions, one per turn. Answer each turn on its own, and keep your earlier answers consistent across the whole run. Quarter figures (all sales and purchases are GST-taxable at the standard 10% rate, so each GST-inclusive amount contains one eleventh of GST): - Total sales including GST: $93,500 - Total purchases including GST: $44,000 - Gross wages paid to employees: $30,000 - PAYG withholding rate applied to those wages: 19% There are no PAYG instalments, fuel tax credits, or other amounts this quarter. Reminder: GST on a GST-inclusive amount is that amount divided by 11, never 10% added on top. Use the public-holiday date for the business's own state, not another state's.
