## Definition

GPT‑5.6 _Sol_ is the flagship AI model tested in the channel's release-day video, launched inside a newly merged ChatGPT desktop app (with ChatGPT Work and ChatGPT Codeex as two presentations of the same engine) and evaluated across programming, writing, design, and intellectual work.

**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.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**.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:> 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 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.- **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.
