0Floor 13 pts · measured

The floor is 13 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison. How the floor is measured · Every change resolves to its category page and to the previous edition's record on the Data page.

The models asked

Fourteen models: the generally available models a buyer meets as a default in an assistant, with search on. Two joined this edition and zero left. A model joins at an edition boundary and stays at least three editions; movement is read over the models both editions asked, so a join never moves a share on its own. The roster rule.
