# v0.6.0 — Realtime Agents & Provider Expansion

*Released April 2, 2026*

A release focused on expanding what agents can do and how many ways you can build them. Realtime speech-to-speech agents are now supported as a first-class pipeline, 24 new providers cover nearly every major AI vendor, and the playground now shows per-turn latency so you can see exactly where time is spent.

## ✨ What's New

### ⚡ Realtime (Speech-to-Speech) Agents

Agents can now run as **Realtime agents** — a new pipeline mode where a single multimodal model handles speech input and output directly, skipping the cascade STT → LLM → TTS chain. Four realtime providers are supported: **OpenAI**, **Gemini**, **Azure OpenAI**, and **xAI**.

To use it, drop a Realtime Agent node on the canvas and connect one of the four realtime provider nodes. The existing pipeline is now called **Cascade Agent** for clarity. Both modes support input variables, the playground, and all conversation flow nodes.

### 🌐 24 New AI Providers

**LLM providers:** Anthropic (direct), Mistral, OpenRouter, AWS Bedrock

**TTS providers:** Groq TTS, Google Cloud TTS, Azure Speech, AWS Polly, Cartesia STT

**STT providers:** ElevenLabs STT, Cartesia STT, AssemblyAI STT, Mistral STT, Google Cloud STT, Azure Speech STT, AWS Transcribe

**Avatar providers:** Anam, Avatario, AvatarTalk, Hedra, Keyframe, LiveAvatar, Simli, Tavus, TruGen

The default TTS provider has been switched from ElevenLabs to **Cartesia**.

### 📊 Provider Latency Metrics

The playground and conversation history now show a **LatencyBar** beneath each agent turn, breaking down STT, LLM, and TTS latency in milliseconds. The session list also shows average latency per conversation so you can compare providers at a glance.

Metrics are collected from LiveKit SDK events, grouped by speech turn, and persisted to the database.

### 🎛️ Adaptive Interruption Handling

The boolean interruption toggle has been replaced with a **3-mode selector** on the Agent node:

* **Off** — interruptions disabled
* **VAD** — voice activity detection, interrupt on any speech
* **Adaptive** — LiveKit's TurnHandlingOptions, which learns from the conversation

## ⚡ Improvements

* **Model lists updated** to match the latest LiveKit documentation
* **agent-python dependencies** updated to latest versions
