Which one would each critic pick

CriticAgent SEkoPick
El Juez——not enough reviews
El Amigo6.86.8no preference
El Crítico6.36.0Agent S — The prerequisites say plainly that the agent runs Python code to control your computer, and the board records no container sandbox, so the blast radius is your desktop.
El Profesor6.86.3Agent S — The 72.60% headline is the agent plus a Behavior Best-of-N wrapper; the agent alone reaches 66% in the 100-step setting against a prior best of 63.4%.
La Inversora6.35.8Agent S — Simular publishes the papers and sells the hosted version, so the open framework is a recruiting document and a demo funnel for a cloud product.
La Jefa5.06.0Eko — Free as a dependency across sixty engineers, TypeScript only, and nothing here runs unattended in a pipeline, so it lives inside an application we build and support.
El Hacker7.58.0Eko — MIT, one package install, native tool-server loading, and a custom base URL on the provider config so my own endpoint is just another model.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
