Director duties and insolvent trading issue-spotting

The same task, run on 28 models. Compare the outputs side by side, or open any one in a popup to inspect it.

Top result: claude-opus-4-8 (medium reasoning) at 100.0% composite. Lowest: deepseek-v4-pro at 0.0%. 28 models compared on this task.

How it ran
  • Each model was given the brief below in a fresh, isolated session with no access to our tools, and returned its answer from scratch.
  • The rendered output was scored 1 to 5 on brief fidelity, visual design, craft, and impact by a four-family vision panel - Anthropic (Claude Opus 4.8), OpenAI (GPT-5.5), Google (Gemini 3.1 Pro), and xAI (Grok 4.3) - using one identical prompt so the scores compare. The published judge score is leave-one-family-out: a model is never scored by a judge of its own family, so same-family self-preference is removed.
The brief

This is a benchmarking hypothetical, not legal advice. The law is as at FY2025-26 (Commonwealth). A sole director of a small proprietary company keeps trading and ordering stock on credit from suppliers, even though the company has stopped paying its debts as they fall due, has no realistic prospect of new funding, and the director has been warned by the bookkeeper that the company looks insolvent. The director also diverts a profitable customer contract to a separate company the director owns. Identify the statutory duties and the specific liability engaged by these facts. In your answer: (a) name the controlling Act, (b) name the directors' duties provisions engaged, and (c) name the insolvent trading provision engaged, and briefly state the key concept behind each.
