Closed Models Dominate Price-Performance Frontier as Open-Weight Share Falls to 3%

Village's LLM Atlas, which maps the strongest model at every price point, shows that by October 31, 2026 only 5 of the 21 models on the price-performance frontier were open-weight, all confined to the cheap end. The share of budgets where an open model is the best buy collapsed from 41% in June to 3%, as closed vendors established both capability and cost advantages across nearly every budget tier.
