Swarm: Open-Source Rust Framework Unifies Multi-Agent Orchestration and LLM Gateway

A developer has released Swarm, an open-source AI framework written in Rust that combines multi-agent orchestration and an LLM model gateway into a single unified system. The project addresses a common infrastructure problem where agent orchestration and LLM request routing are handled by two separate, unrelated frameworks. In its orchestration mode, Swarm uses a Planner Agent to generate execution plans, an Executor Agent to manage task workflows, and domain-specialist agents that interact with tools via the Model Context Protocol. Its gateway mode exposes an OpenAI-compatible API endpoint that supports multi-provider routing across services like Groq, Google Gemini, OpenAI, and local backends such as Ollama and vLLM. Both modes run on a shared Tokio async runtime, with type-safe inter-agent messaging and a built-in LLM-as-a-Judge evaluation loop for output verification.
