How can i speed up how fast the ai agent joins the room. My agent sometimes joins the room 1 minutes after the user has joined. My agent us deployed in livekit cloud and I notice that this issue is common when the agent hasn’t been used for a while and is then used on my website

Thanks for reaching out, David. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
To help your AI agent join a room more quickly, especially after it’s been inactive for a while, here are some friendly tips you can try: • Reduce Cold Start Impact: Consider using the
prewarm
function to preload resources like models when the worker starts up. This way, your agent won’t face delays from loading dependencies the first time it’s used. • Dispatch Agent Early: Try dispatching the agent during token generation so it can connect alongside the user, which helps cut down on waiting time. • Optimize Room Creation: Instead of explicitly calling
CreateRoom()
, you can let LiveKit automatically create the room when the first participant joins. This often speeds things up. • Optimize Initialization: Load any static data within the
prewarm
function and pass user-specific information through metadata or attributes. This helps avoid delays during runtime when fetching data. • Monitor Agent State: Set up event listeners to know exactly when the agent connects, and use that to give your users helpful feedback through the UI, making the experience smoother. Following these steps can really help your agent join rooms faster, even after it’s been idle. If you’d like, I’m here to walk you through any of these strategies in more detail—just let me know!

Do you know why this happens

Thanks so much for reaching out! The delay you're noticing with your AI agent joining the room is often due to what's called a cold start. This simply means that if the agent hasn’t been active for a while, LiveKit scales it down to save resources. So, when it’s needed again, it takes a little time to wake up, load everything it needs, and connect to the room. There are other things that might add to the delay too, like fetching access tokens, initializing models, or setting up rooms. A great way to reduce these wait times is by prewarming resources or dispatching the agent a bit earlier. If you’d like, I’m here to help walk you through these steps or answer any questions you have. Just let me know!
