GPT-5.6 Luna and GPT-6 Sol carry source-labelled ratings with evidence and any approved estimates in their category breakdowns. Models may use different benchmarks and test settings. This is an indicative composite, not a controlled head-to-head comparison or community Elo. Admin-approved sentiment estimates fill categories without accepted benchmark results. Estimates are labelled and do not increase benchmark coverage.
