Tier B

Established: 15 or more models scored, or curated RL directories rate it.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

How we got to tier B

Adoption: built by AfterQuery, Aptura. Tier C.
Not yet read on X.
In curated RL directories: 6 points, a floor of B. Raised to B.
Confirmed: a line from its own site or paper places it.

A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
