Tier B

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.

  • 20 models scored

How we got to tier B
  1. Adoption: 20 models scored; built by Proximal. Tier B.
  2. Not yet read on X.
  3. In curated RL directories: 4 points, a floor of B.
  4. Not yet confirmed by a line from its own site or paper.

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

Not on the map yet: no line from its own site or paper places it in a domain.
