Introducing PII Redaction Support
This release adds PII redaction support for Agent Observability. It semantically redacts detected entities from chat history and audio recordings. It also filters sensitive data from logs and traces while retaining useful diagnostic context.
To support this feature, we renamed sensitive trace attributes and log fields emitted by the framework. If your third-party observability queries depend on these names, update them when you upgrade.
Expressive mode allows voice agents to speak with natural prosody and emotion. Speech delivery is determined by emotion tags generated from the context of the conversation. Enable expressive mode in your AgentSession:
from livekit.agents import AgentSession, inference
session = AgentSession(
stt=inference.STT(model="deepgram/nova-3", language="multi"),
llm=inference.LLM(model="google/gemma-4-31b-it"),
tts=inference.TTS(model="fishaudio/s2.1-pro", voice="b347db033a6549378b48d00acb0d06cd"),
expressive=True,
# ... vad, turn_detection
)See the documentation and the blog post for more information.

Warning
console and dev modes are deprecated in favor of lk agent (#6656). Existing workflows that shell out to python agent.py console or python agent.py dev should migrate to the lk agent CLI.
Important
Inference Ink-2 speech onset fix (#6630) — if you rely on the STT model for interruption detection without a local VAD, upgrade for this fix. Previously the provider's speech-onset signal was delayed until first non-empty interim transcript, so STT interruptions could be delayed on Ink-2 via Inference. Setups with a local VAD in the pipeline are unaffected.
