Simulations with
verifiable rewards

Refresh builds simulation engines for coding and computer use, focused on helping labs deliver an effective AI coworker.

What we're building toward

We believe AI will work alongside you on almost everything, at work and at home. We build simulation engines that help AI empower human productivity, by teaching it how to use the computer exactly like you would. On the terminal and on the GUI.

Accelerating RL
Data Ops

We partner with frontier labs and enterprises to build training gyms, datasets, and infrastructure to support the development of the next set of capabilities in LLMs.
