Telos-OS is an open-source Python framework that turns real-world optimization problems into declarative YAML manifests. Define your variables, constraints, and objectives — a MILP solver finds the optimal answer. Actuators execute decisions automatically across Docker, Kubernetes, or your own stack. No optimization PhD required. 16+ production-ready templates spanning energy dispatch, traffic routing, manufacturing, portfolio allocation, and more. MIT licensed. pip install telos-os and solve.
