Do agent-built spreadsheets hold up to professional finance standards? MBABench 2.0 checks each answer against an answer key and each workbook against 129 criteria across 12 categories, with the best agent passing only 16% of the tasks. Proud to support @ThomsonYenTY, @hsnamkoong, and the @Columbia_Biz team through Open Benchmarks Grants, and excited to see them launch the benchmark at Frontier Data Summit yesterday.

Tier C

Niche: a handful of models scored, or built by an RL vendor.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
