Over 100 closed-loop controllers, running in production.
Imubit is the only commercial solution applying closed-loop reinforcement learning at scale in a production environment. Here is where its controllers run, and what counts as one.
- Over 100closed-loop controllers deployed worldwide
- 300+applications deployed, from inferentials to closed loop
- 7+ yearsof closed-loop engagement in production
- 13approved U.S. patents
What we count.
A closed-loop controller is a Deep Learning Process Control® controller running in closed loop on a production unit. It writes its moves to the APC where there is one, or directly to the DCS, always inside the envelope the plant's engineers set.
An application is anything Imubit has deployed in production, from an inferential, a quality estimated from process signals, to an advisory model to a closed-loop controller. The 300+ applications include the controllers, so the two figures are never added together.
Results, with their scope.
- $0.25/bblmargin improvement, refining
- 2 to 3%increase in jet recovery on top of existing APC, at one refinery's naphtha and jet complex
- 33%reduction in furnace downtime on one crude furnace at one refinery
- 20 to 30%reduction in process variability on one customer's kiln pyroprocess, in closed loop
- 0.5 to 1%increase in yield across multiple sites, at the Model step, for a multi-site chemical manufacturer
- 15 to 30%reduction in energy consumption where energy is the optimization target

ARC Advisory Group positions Imubit as a Leader in the ARC MarketMap 2026: Autonomous Execution Agents, Continuous Process Edition, its study of AI that executes decisions in the plant rather than only recommending them.
Autonomy comes in steps, with experts in charge
Plants will not jump to full autonomy. It comes in steps, with domain experts, deterministic plant models and generative AI working together.
