Why this result
Grok 4.5 is clearly ahead on the BenchAlign aggregate, 76.72 to 67.54. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4.5's sharpest advantage is in agentic, where it averages 83.3 against 69.4. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 83.3% to 63.8%. Inkling does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Grok 4.5 is also the more expensive model on tokens at $2.00 input / $6.00 output per 1M tokens, versus $1.87 input / $4.68 output per 1M tokens for Inkling. Grok 4.5 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 500K for Grok 4.5.
