When building RL tasks and evals, it's difficult to distinguish between actual model capability failures and bad RL task design. We're sharing some our task design principles so you can write better tasks before ever evaluating a model on them.

Most browser evals look clean in a sandbox and fall apart on the live web. We wrote a walkthrough with @browserbase on how to write browser evals that hold up on the live web. Sites update, graders reward faked outputs, and bot detection kill your runs before the agent even starts. If you're benchmarking browser agents, your scores are probably noisier than you think.

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 HUD. Tier C.
Not yet read on X.
In curated RL directories: 2 points, a floor of C.
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.
