Pick Inkling if you want the stronger benchmark profile. Grok 4.3 only becomes the better choice if multimodal & grounded is the priority or you want the cheaper token bill.
Confidence note. This is a partial-evidence comparison with 4 shared benchmark results across 3 evidence categories; 4 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
Inkling is clearly ahead on the provisional aggregate, 69 to 63. 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 coding, where it averages 68.6 against 47.3. The single biggest benchmark swing on the page is HLE, 35% to 46%. Grok 4.3 does hit back in multimodal & grounded, 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 $1.25 input / $2.50 output per 1M tokens for Grok 4.3. Grok 4.3 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.
