Devin Desktop’s latest Windsurf Next build includes four model codenames that were not present in the prior build, according to community monitoring.
X user @aitrackerbot noted that the new build adds Theia, Obsidian 2, Obsidian 3 and Slate 2, each with its own reasoning levels, and that no lab attribution is provided.
Another user, @fayequepeerzade, reported the same four codenames and suggested the list could signal stealth models or upcoming releases, speculating that one might be Kimi K3.1.
