How GPT‑5.6 _Sol_ Appears in This Channel GPT‑5.6 Sol is the flagship model explored in the release-day video I Tested GPT‑5.6 Sol for a Month — the result of roughly a month of testing inside Every, with one break in access along the way before testing resumed. What Was Tested Sol is evaluated as a model plus an environment: it launches inside a single merged ChatGPT desktop app with two surfaces, ChatGPT Work and ChatGPT Codeex — the same engine in two presentations. Work hides the code; Codeex shows it in a programming-like way. Testing was organized around four categories of intellectual work: programming, writing, design, and intellectual work. The Framing Sol together with the ChatGPT environment is positioned as the gold standard — the best model in the best environment. The video's central claim, from the release-day moment: [moment: 4]I believe this model offers a new approach to intellectual work, familiar to programmers, but now available to everyone in ChatGPT Work and ChatGPT Codeex. The Presenter The exploration is led by Dan Schipper, co-founder and CEO of Every, whose subscription gives the team access to the model essentially the minute it comes out. [moment: 100] - GPT‑5.6 Sol is a flagship model tested for about a month inside Every and introduced on release day.- It launches in a single merged desktop app: ChatGPT Work hides the code, ChatGPT Codeex shows it — same model underneath.- Testing spans programming, writing, design, and intellectual work, with comparisons against Fable and Opus 4.8.- Sol plus the ChatGPT environment is framed as the gold standard for intellectual work.
