In the DeepFinance benchmark of 21 end-to-end private equity and investment banking tasks that take a human professional an average of 27.1 hours, the best configuration, GPT-6 Astra with max reasoning, satisfies 57.6% of rubric criteria, and the top four configurations are not statistically distinguishable
The DeepFinance benchmark, published on arXiv on 7 Nov 2026, measured the percentage of rubric criteria satisfied by 22 model configurations on 21 end-to-end private equity and investment banking tasks. The best configuration, GPT-6 Astra with max reasoning, satisfied 57.6% of rubric criteria, and the top four configurations were not statistically distinguishable.

Models can find relevant data and calculate accurately yet still fail to use that information correctly in complex decisions.
More on Models
- AI models can now win gold at the International Mathematical Olympiad, yet Stanford's 2026 AI Index found they still fumble a task most children master early. Across ClockBench's 180 clock designs and 720 questions, the top model, GPT-5.4 High, read analog clocks correctly only 50.6% of the time, versus 90.1% for humans
- After briefly nearly closing in 2024, the performance gap between the best closed-weight and open-weight AI models widened again on the Arena leaderboard. As of March 2026, Stanford's 2026 AI Index finds the top closed model leads the top open model by 3.3%, up from a 0.5% lead in August 2024
- Stanford's 2026 AI Index tracks how AI models perform on GPQA Diamond, a set of PhD-level chemistry and physics questions designed to resist Google searches. Mean model accuracy on the benchmark reached 93% in 2025, compared with an expert human validator baseline of 81.2% -- AI models now beat PhD-level experts by 12 points on GPQA Diamond
