@millions-hair-24956 I want to change the used LLM for the voiceagentpiple after a function from functioncontext. I used agent.llm = llm_configuration but there is the error AttributeError property 'llm' of 'VoicePipelineAgent' object has no setter how can i handle this ?

To change the LLM used by a

VoicePipelineAgent

, you cannot directly set the

llm

property because it does not have a setter. Instead, you can modify the LLM instance by using the

before_llm_cb

callback to dynamically adjust the LLM configuration before each call. This allows you to inject a new LLM instance or modify the existing one as needed. Here's a basic example of how you might implement this:

from livekit.agents import VoicePipelineAgent, llm

async def before_llm_cb(agent: VoicePipelineAgent, chat_ctx: llm.ChatContext):
    # Create a new LLM instance or modify the existing one
    new_llm = llm.LLM()  # Replace with your LLM configuration
    agent._llm = new_llm  # Directly modify the internal attribute

agent = VoicePipelineAgent(
    vad=your_vad_instance,
    stt=your_stt_instance,
    llm=initial_llm_instance,
    tts=your_tts_instance,
    before_llm_cb=before_llm_cb
)
