An environment corpus — built, connected, and graded.

Environments for frontier models.

We build the environments where AI models do real work. Every step is checked against the right answer, so the model learns from what it gets wrong.

How it works

From a skill to a graded test, in five steps.

01

Perceive

Pick a skill and find where models fail at it.

02

Represent

Turn it into tasks that each have a clear right answer.

03

Build

Build the test so it cannot be gamed or memorized.

04

Scale

Make many versions. The early ones become training data.

05

Choose

Measure how often models succeed, then build the next test around what they miss.

Where we work

The areas we point it at, most important first.

Safety

Keeping AI safe and overseen. The first priority.

Defense

High-stakes work and stress-testing.

Science

Bio, pharma, and research.

Commerce

Real work inside real companies. Live today.

Why Idler

Real, broad, and built for the best models.

Real

Built from real work, not made up. The skills carry over.

Broad

Coding, using tools, long tasks, and recovering from mistakes.

Frontier

Built for the best models, on what they cannot do yet.
