-1. Arch-Guard: A fast and efficient model for jailbreak attempts; improves performance over Meta Prompt Guard
+1. Plano-Orchestrator is a family of state-of-the-art routing and orchestration models that decide which agent(s) or LLM(s) should handle each request, and in what sequence. Built for multi-agent orchestration systems, Plano-Orchestrator excels at analyzing user intent and conversation context to make precise routing and orchestration decisions. Designed for real-world deployments, it delivers strong performance across general conversations, coding tasks, and long-context multi-turn conversations, while remaining efficient enough for low-latency production environments.
 2. Arch-Router: A fast preference-aligned routing model that guides LLM selection by matching queries to user-defined domains (e.g., travel) or action types (e.g., image editing) – offers a practical mechanism to encode preferences in routing decision.
 3. Arch-Agent: Designed to power sophisticated multi-step and multi-turn workflows, Arch-Agent excels at handling complex, multi-step tasks that require intelligent tool selection, adaptive planning, and seamless integration with external APIs and services.
