You should try Silico. Not only for mech interp, but for AI Research in general. Goodfire have put a lot work into building a great interface for long-horizon agent-driven research.

What is PopuLoRA?

PopuLoRA: Co-Evolving LLM Populations for Reasoning Self-Play (arXiv:2605.16727, 2026-05-16)

Tier C

Niche: a handful of models scored, or built by an RL vendor.

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 C

Adoption: built by Vmax. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
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.
