About
GPT-5.6 is what actually runs inside HumanLike Coworker today. We expose it as three named tiers rather than raw effort settings, because in practice teams pick a speed/quality point once and keep it: Luna for everyday actions, Terra for drafting and tool use, Sol when the answer has to be right. Luna is the default for new workspaces.
