Plexus is the control plane for production AI systems at Anthus. It turns model prompts, classifiers, and agent procedures into versioned operational assets with evaluation, deployment controls, and feedback loops that can keep improving after launch.
Most teams can get a demo working. The difficult part is operating an adaptive system without losing track of what changed, why it changed, and whether the new version is better. Plexus is where Anthus puts that operational discipline.
Plexus sits near the center of the stack. Tactus can call into it through MCP. Korporus can host interfaces and workers around it. Biblicus, Virtuus, and Caducus support adjacent knowledge, storage, and operator workflows.
A common pattern is Tactus + Plexus + Caducus: define the procedure, evaluate and improve it, then keep operators informed once it is live.
