Pass realtime_service_mode=RealtimeServiceModeConfig() through every realtime LLM service example (base, async-tool, video, text-output, persistent-context, update-settings, MCP) so context aggregation uses the new realtime-mode semantics instead of relying on local VAD as a workaround. Where examples previously wired SileroVADAnalyzer into LLMUserAggregatorParams to coax turn frames out of services that don't emit them server-side (AWS Nova Sonic, Ultravox, Gemini Live), the local VAD is now removed. realtime_service_mode keeps context writes correct without it, and the Phase 1.5 server-side InterruptionFrame fixes for Nova Sonic and Ultravox keep the bot from talking past the user when they barge in. Transcript-logging event handlers move from on_user_turn_stopped / on_assistant_turn_stopped to on_user_message_added / on_assistant_message_added, which carry the finalized text in realtime mode (the turn-stopped events fire before the message is finalized, so their `content` is None in that mode). For services that don't emit user-turn frames (Gemini Live, AWS Nova Sonic, Ultravox) the example now carries a Tier 1 comment block that spells out which downstream processors won't activate, how to add local VAD if needed, and the caveat that locally-generated turn boundaries are a heuristic that may diverge from server-side ground truth. Adds examples/realtime/realtime-openai-local-vad.py, a new variant of the OpenAI Realtime example that disables OpenAI's server-side turn detection and drives turn boundaries locally — useful when you want a turn analyzer like LocalSmartTurnV3 to decide when the user is done speaking. Server-emitted turn frames are still preferred when available. The Gemini Live local-VAD variant already existed; it's been updated in place rather than rewritten.
🎙️ Pipecat: Real-Time Voice & Multimodal AI Agents
Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. Orchestrate audio and video, AI services, different transports, and conversation pipelines effortlessly—so you can focus on what makes your agent unique.
Want to dive right in? Run
pipecat init quickstartor follow the quickstart guide.
🚀 What You Can Build
- Voice Assistants – natural, streaming conversations with AI
- AI Companions – coaches, meeting assistants, characters
- Multimodal Interfaces – voice, video, images, and more
- Interactive Storytelling – creative tools with generative media
- Business Agents – customer intake, support bots, guided flows
- Complex Dialog Systems – design logic with structured conversations
🧠 Why Pipecat?
- Voice-first: Integrates speech recognition, text-to-speech, and conversation handling
- Pluggable: Supports many AI services and tools
- Composable Pipelines: Build complex behavior from modular components
- Real-Time: Ultra-low latency interaction with different transports (e.g. WebSockets or WebRTC)
🌐 Pipecat Ecosystem
🧩 Multi-agent systems
Need multiple AI agents working together? Pipecat Subagents lets you build distributed multi-agent systems where each agent runs its own pipeline and communicates through a shared message bus. Hand off conversations between specialists, dispatch background tasks, and scale agents across processes or machines.
📱 Client SDKs
Building client applications? You can connect to Pipecat from any platform using our official SDKs:
JavaScript | React | React Native | Swift | Kotlin | C++ | ESP32
🧭 Structured conversations
Looking to build structured conversations? Check out Pipecat Flows for managing complex conversational states and transitions.
🪄 Beautiful UIs
Want to build beautiful and engaging experiences? Checkout the Voice UI Kit, a collection of components, hooks and templates for building voice AI applications quickly.
🛠️ Create and deploy projects
Create a new project in under a minute with the Pipecat CLI. Then use the CLI to monitor and deploy your agent to production.

⚡ Getting started
You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you're ready.
-
Install uv
curl -LsSf https://astral.sh/uv/install.sh | shNeed help? Refer to the uv install documentation.
-
Install the module
# For new projects uv init my-pipecat-app cd my-pipecat-app uv add pipecat-ai # Or for existing projects uv add pipecat-ai -
Set up your environment
cp env.example .env -
To keep things lightweight, only the core framework is included by default. If you need support for third-party AI services, you can add the necessary dependencies with:
uv add "pipecat-ai[option,...]"
Using pip? You can still use
pip install pipecat-aiandpip install "pipecat-ai[option,...]"to get set up.
🧪 Code examples
- Foundational — small snippets that build on each other, introducing one or two concepts at a time
- Example apps — complete applications that you can use as starting points for development
