OpenAI released GPT-5.6 with a stratified model lineup (Luna, Terra, Sol) and 36 API variants, but the launch caused UX regressions and unexpected cost overruns, prompting two usage-limit resets and a corrective roadmap. GPT-5.6 Luna at the lowest effort setting costs 25 times less than GPT-5.5 at highest effort while delivering superior health-domain performance, though overall capability gains remain mixed across domains. The ecosystem is shifting toward harness-centric competition, with routing, memory, and orchestration tools becoming the primary differentiator as frontier model quality converges.
