Plano is an AI agent orchestrator and LLM gateway proxy that unifies access to multiple AI providers through a single interoperable interface. It functions as a model routing engine that decouples applications from specific vendors using semantic aliases, allowing traffic to be shifted between providers without modifying application code.
The system distinguishes itself with intent-based agent routing, which directs prompts to specialized agents based on semantic analysis. It features an interceptor-based filter chain system that acts as guardrail middleware to enforce safety policies, rewrite prompts, and validate inputs before they reach a model.
The project covers a broad operational surface, including automated OpenTelemetry-driven observability for tracing agentic signals, conversational state management for session affinity, and reliability tools such as automatic model fallbacks and endpoint load balancing. It also provides capabilities for converting natural language into structured backend function calls.
The server can be deployed as a containerized image in Docker or Kubernetes.
