OFF POLICY

We build rich RL environments for frontier labs. Our novel verifiers make complex, long-horizon work trainable.

Boulton and Watt rotative beam engineA blue-ink perspective engraving of a steam engine on an open cast-iron bed. A rocking beam connects the cutaway cylinder and its reciprocating piston to a large six-spoked flywheel. A belt-driven centrifugal governor turns beside the cylinder. All connecting rods remain rigid through a complete revolution. Labels: a, cylinder; b, centrifugal governor; c, flywheel.a. Cylindera.b. Centrifugal governorb.c.
