OSP is Okuma's in-house control, unusual for being developed together with the machine and drives (Okuma's 'mechatronics'). That integration shows up as strong thermal compensation, collision avoidance (Collision Avoidance System) and an open, PC-based architecture.
Because Okuma builds control, machine and servos as one system, OSP machines are tightly matched and tend to hold value well. Generations run from OSP-P200/P300 up; the version and installed apps affect capability and resale.
