Why this result

Inkling is clearly ahead on the provisional aggregate, 69 to 61. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Mistral Medium 3.5 128B is also the more expensive model on tokens at $1.50 input / $7.50 output per 1M tokens, versus $1.87 input / $4.68 output per 1M tokens for Inkling. Mistral Medium 3.5 128B is the reasoning model in the pair, while Inkling is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Inkling gives you the larger context window at 1M, compared with 256K for Mistral Medium 3.5 128B.
