@trycua ↗What is Cua-Bench?
Cua-Bench measures AI agents' computer-use mastery on desktop and mobile tasks, including expert KiCad schematic (EDA) tasks, with a harness for evaluation and training.
Computer use mostly
“Cua-Bench is a collection of desktop and mobile tasks with a harness for evaluation and training to help agent makers quantify their agents' computer-use mastery.”
cua.ai/cuabench ↗“On 25 expert-authored KiCad schematic tasks, the best frontier agent we tested cleared 6 of 25”
cua.ai/cuabench ↗“This task tests if an agent can detect a dangerous clipboard injection”

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.
- built by Cua
- in curated RL directories (6 pts)
How we got to tier B
- Adoption: built by Cua. 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.
