A benchmark for real-time physical judgment.

Same robots, same situations, same controllers. Only the decision model changes. Pick a model and watch it decide, live in your browser.

robojev bench is the benchmark; Jev, d1, Decision-1, GPT-6 Luna, Solar Flash and robo-jev are models you can run in it.

How it works

Only the decision model changes.

Every environment splits the robot’s work into three layers. The task and the executor stay fixed; the decision model between them is the one you choose.

L3THE PLAN

Task

Sets the goal and the order of work: the tables to serve, the tubes to prepare, the order to deliver.

FIXED FOR EVERY MODEL
L2UNDER TEST

Decision model

Reads the robot’s state as it moves and answers typed questions: what next, who first, wait or go.

Executor

Carries each answer out with the environment’s own controllers.

FIXED FOR EVERY MODEL
  1. 01

    Same harness

    Every model gets the same state, the same questions and the same executor.

  2. 02

    Real time

    Robots ask as they move, once a second or faster. A late answer is carried out late.

  3. 03

    Typed questions

    Choice, score or yes/no, through OpenRouter’s Decisions API.

  4. 04

    The robot’s senses only

    No model sees the simulator’s ground truth. Where a stand-in replaces a perception model, the environment’s page names it.

03

Models

Choose one on any environment’s page.

The models the site runs answer through OpenRouter’s Decisions API. No scores yet: watch them decide.

Bring a model

Any model that answers OpenRouter’s Decisions API can run in every environment.

REQUIREMENT
Takes a description of the state and choice, score and yes/no questions, and answers with probabilities.
SAME HARNESS
Every model runs on the same harness: state, questions and executor. The harness was first built with Jev, and each version of it is fixed.
REAL TIME
Robots ask once a second or faster, so answers should come back within about a second. Until an answer comes, the robot carries on with its last decision, as a real robot would.
