livekit-agents@1.8.8

GPT-Live through LiveKit Inference

You can now run GPT-Live with your LiveKit credentials instead of a separate OpenAI key. inference.DuplexModel handles its protocol, and you can adopt it directly with a model string:

session = AgentSession(llm="openai/gpt-live-1")

New providers and models

• OpenAI GPT-Live 1: now available through LiveKit Inference.
• Google Gemini Live: adds Inference model-string support for google/gemini-3.8-live, google/gemini-3.8-live-extended-thinking, and google/gemini-live.
• xAI Grok Voice 3.0: replaces Think Fast 2.0 in the Inference and xAI plugin model lists.
• TypeSafe Jev: a new decision-model plugin supports jev-1.13.0 and OpenRouter’s Decisions API for background probability, choice, and score evaluations without delaying replies.

Breaking changes

• OpenAI realtime: inference.RealtimeModel no longer subclasses the plugin’s openai.realtime.RealtimeModel; update isinstance checks. Incidental wildcard exports such as realtime_model.logger are no longer available.
• GPT-Live voices: cedar replaces the unsupported aster voice; update voice selections.

Behavior changes

• LiveKit Inference: retired GPT Realtime 1.5/2 and Grok Voice Think Fast 2.0 IDs remain accepted with deprecation warnings. Realtime inference_class is deprecated and no longer sent.
• Google Gemini: 3.x reply instructions now use wrapped user turns.
• xAI: hosted sessions now emit one final user transcript per turn.

XML-aware TTS chunking, realtime startup retries, turn-audio flushing, and interruption handling are more reliable.
