Highlights

🛣️ The Path to v1.0 — A Major Step

v0.13.0 is a significant release for our journey to V1.0. It introduces a brand-new Multi-Agent Network runtime and LiveAgent for full-duplex realtime voice. Plus, A2A v1.0 and MCP now in Beta to complete the connectivity story.

📍 Release Roadmap

🌐 Network — Multi-Agent Runtime (NEW)

Other frameworks treat an agent or a graph as the primitive. AG2 Beta makes the channel between agents the primitive — a durable, identity-scoped, protocol-typed container. Open it, work inside it, close it. The channel is the artifact.

• 🔗 Channel as the unit – Append-only event log per channel. Adapter state is derived from the log, so a hub restart is a non-event.
• 🎭 Choreography you can dial in – From open multi-party discussion to fully declared workflows, all on the same primitive. Four built-in patterns ship today:
  • consulting — 1↔1, one round (strict Q+R, auto-close)
  • conversation — 1↔1, multi-turn (bidirectional, long-running)
  • discussion — N-party turn-taking (round-robin, dynamic, or static ordering)
  • workflow — orchestrated by a declarative TransitionGraph, with conditions and dynamic handoffs (great for transitioning your classic AG2 group chats - Guidance)
• 🛠️ Design your own orchestration – The ChannelAdapter protocol is small (~50 lines for a custom adapter). Define your own manifest, state, and turn-taking rules; reuse the durability and identity layers for free.
• 🪪 Identity is three records – Passport (immutable, hub-stamped), Resume (mutable track record + observed stats), SKILL.md (LLM-facing doc). Discovery ranks by observed outcomes.
• 🤝 Federation with Passport + Visa – A channel can span two hubs the same way a TCP connection spans two networks. Cross-org channels are the base case, not an extension.
• 👤 HumanClient – Humans are peers on the network, not a special case.

🎮 Try it in the Playground – An 8-page hands-on walkthrough (~30 min) with full code examples. Build a hub, register agents, open channels, walk through all four turn-taking patterns, hub-side governance, and write your own adapter from scratch.

🎙️ LiveAgent — Realtime Voice (NEW)

New autogen.beta.live module for full-duplex voice agents backed by provider realtime APIs. Unlike turn-by-turn STT/TTS pipelines, LiveAgent opens a single bidirectional session for the entire conversation — audio flows in and out continuously.

• 🎤 Single bidirectional session – No turn-by-turn round trips.
• 🛑 Built-in VAD and barge-in – Voice activity detection and interruption support out of the box.
• 🛠️ Same tool surface as Agent – @agent.tool decorator works identically; tool calls route through AG2's normal executor.
• 🌐 Provider-neutral – OpenAI Realtime (10 voices: alloy, ash, ballad, coral, echo, sage, shimmer, verse, marin, cedar) and Gemini Live (8 voices: Aoede, Charon, Fenrir, Kore, Leda, Orus, Puck, Zephyr).
• 📝 Text-only mode – Keep the realtime session for low-latency turn detection but disable audio output entirely.
• 🔊 Audio peers – SoundDevicePlayer and SoundDeviceRecorder share the conversation context with the agent.

📔 Docs: LiveAgent · STT & TTS alternative also available.

🔗 A2A v1.0 — Now in Beta

A2A is now available in the Beta framework via the new autogen.beta.a2a module.

• 📡 Expose any AG2 Agent over A2A via A2AServer
• 🔌 Connect to a remote A2A endpoint as if it were an LLM provider via A2AConfig
• 🚚 Transport-agnostic: JSON-RPC, HTTP+JSON (REST), or gRPC
• 📥 Tasks & push notifications for long-running work
• Install with pip install "ag2[a2a]"
