Thanks for reaching out, tharindu. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thanks — I’m sorry you’re stuck. I’m responding about changing the STT model in the Cloud Agent Builder (it keeps reverting to Cartasia Ink Whisper and you want Deepgram). Please try these steps first: 1. Open your agent in LiveKit Cloud Agent Builder and open the agent configuration panel. 2. In the Speech-to-text / STT dropdown select Deepgram and choose the specific Deepgram model if shown. 3. Click Save and then refresh the page. 4. If it still reverts, try in an incognito/private window or clear your browser cache. A few things that commonly cause reversion: • Deepgram not fully configured (missing/invalid Deepgram API key). • A cached UI state or browser extension interfering. • You changed the model in exported code or another configuration source that overwrites the Builder settings. Quick checks for me to help further: • Do you have a Deepgram API key configured for this agent? • Are you changing the model only in the Builder UI (not in exported code or another environment)? • Which browser are you using, and did you already try incognito? Tell me those answers and I’ll walk through the next troubleshooting steps. Sources: Deepgram STT | LiveKit docs

am i need to setuo deepgram api key
t
Yes — to use Deepgram as the STT model in Cloud Agent Builder you must configure a Deepgram API key for the agent. Please do the following: 1. Obtain a Deepgram API key from your Deepgram account. 2. In the Cloud Agent Builder, open your agent’s settings and locate the STT / provider credentials area. 3. Paste the Deepgram API key into the Deepgram credential field and save. 4. Select Deepgram from the STT dropdown, choose the model, save, then refresh the Builder. Do you already have a Deepgram API key, or would you like instructions for where to get one?

cant find api key place location ?

Thanks — I’m replying about where to put a Deepgram API key in Cloud Agent Builder. You do not need (and won’t find) a Deepgram API key field in the Agent Builder UI. Agent Builder uses LiveKit Inference, which gives access to Deepgram models through your LiveKit Cloud project credentials (
LIVEKIT_API_KEY
, 
LIVEKIT_API_SECRET
, 
LIVEKIT_URL
). To use Deepgram in the Builder: • Open your agent in the Cloud Agent Builder. • In the Models or STT section, open the Speech-to-text / STT dropdown and select a Deepgram model (e.g., 
deepgram/nova-3
). • Save and refresh; no separate Deepgram key is required. If you want to use your own Deepgram account/key instead: • Export the agent code from Agent Builder. • In the exported project, add your 
DEEPGRAM_API_KEY
(e.g., in the 
.env
) and configure the Deepgram STT plugin. • Deploy the agent from your local environment. Would you like steps to export the agent and set a personal Deepgram key, or help selecting the Deepgram model inside the Builder?
