OpenAI’s frontier output token pricing has fallen sharply in 2026 amid an industry-wide price war, with the company launching GPT-6.1 Sol at $2 input/$10 output per million tokens in late September and GPT-6 Luna at $0.10/$0.50, alongside cached-input reductions that lower effective costs for high-volume workloads. These moves followed similar cuts from Anthropic’s Claude Opus 5.5 and competitive offerings from Google Gemini and xAI Grok, reflecting efficiency gains in model training and inference that enable labs to maintain capability while compressing rates. Trader sentiment for 2026 hinges on whether OpenAI sustains premium frontier pricing near $50 for models like GPT-6 Astra or accelerates commoditization of even top-tier output through further tiered releases or batch/caching optimizations before year-end.
