Why this result
Inkling is clearly ahead on the BenchAlign aggregate, 67.54 to 56.79. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Inkling's sharpest advantage is in mathematics, where it averages 97.1 against 67.1. The single biggest benchmark swing on the page is HLE, 46% to 34.7%. Kimi K2.6 does hit back in agentic, so the answer changes if that is the part of the workload you care about most.
Inkling is also the more expensive model on tokens at $1.87 input / $4.68 output per 1M tokens, versus $0.95 input / $4.00 output per 1M tokens for Kimi K2.6. Kimi K2.6 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 Kimi K2.6.
