For Ecosystem

One engine. Every role.

Every simulation on internship.ai runs on the Job Simulation Engine: CareerLLM reasoning over millions of career data points to compose briefs, datasets, apps, and graders. Soon, the framework behind it goes open source.

The engine room

CareerLLM at the core.
An engine around it.

CareerLLM.

Our own model layer, tuned on millions of career data points: live job ads, briefs, rubrics, and graded submissions from real simulations.

The Job Simulation Engine.

Turns any job description into a runnable simulation: briefs, datasets, sandboxed apps, and deterministic graders that score real work.

An open framework. Soon.

Define your own roles and apps, plug them into the engine, and share them with everyone. The Job Simulation Framework goes open source soon.

The simulated app ecosystem

59 simulated apps.
One engine underneath.

Faithful, sandboxed recreations of the tools real teams work in, from IDEs and BI dashboards to SIEM consoles, all speaking to the same engine.
