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 are as at FY2025-26. An Australian business issues a tax invoice for $1,100 including GST at the standard rate of 10%. State, in dollars: (a) the GST amount included in the invoice, and (b) the GST-exclusive price.
