Same model, different work, different answer

54% → 18%
GPT-6 Luna on PubSec work, then on Banking work

18 models have run both benchmarks. Most land in a similar place on each. GPT-6 Luna does not: 54% of its PubSec work was right, and 18% of its Banking work.

Share of work right: PubSec (first bar) and Banking (second).

Banking tasks lean on long, exact sums: totals over dozens of rows after the exceptions are taken out, where being close is still wrong. Muse Spark 1.3 held steady (64% and 63%).

Writing more doesn't fix it. Nemotron 3.5 Lightning wrote about 38,000 tokens of working for each Banking task, most of it reasoning nobody reads, and got 2% of them right.

A benchmark score describes the work that was tested. It is a poor guide to work that was not.

We marked our own answer key

When three or more models gave the same answer and our key marked it wrong, we checked the key by hand. It was right 13 times out of 17. The other 4 times the models were. We fixed those and regraded everything.
