Models build first- to third-year investment banking analyst models, such as three-statement and leveraged buyout models, with formatting and citations. OpenAI grades the outputs internally.

The GPT-5.2 post called it Investment banking spreadsheet tasks, with GPT-5.2 at 68.4 under both names. The grading method is not described, so model-judged is assumed.

GPT-5.5 Pro leads with 88.6% among models released by April 2026

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in April 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 GPT-5.5 Pro 88.6%
