Comparison basis
Official sources and verification date
Release date, model name, price and limits come from Anthropic’s official launch and model documentation. VUST separately checks its product integration and claims neither partnership nor universal model superiority.

Direct answer
How VUST's Opus entry works
Open the direct link and @vustbot first confirms the exact model it will run — today that is “VUST Max — Claude Opus 5.5,” not Claude Opus 5 itself. Pro and Max can run it inside their allowance; other users keep the prompt and see pass options, top-up, or an explicit return to the previous available model.
