Frank Downing(@downingARK):Grok 4.6 lands in a great spot on the Pareto frontier per Artificial Analysis indexing. Same avg. score as GPT 5.6 Sol (max) and 32% cheaper. Contrary to popular assumptions, of the 16 models on the frontier, only 2 are open, meaning if you are opting for an open model to save money you are likely overpaying.
