No phone numbers or SIP, so you bridge Twilio or another carrier yourself.\n\n**GPT-Live.** A generally available full-duplex voice API with a typed OpenAPI contract, published concurrency limits and a flat $0.05 a minute for the voice session. Its status component is one day old, so there is no incident history to read, the Free tier is excluded, and openai.com refused our reader, so the terms and privacy policy were not read.\n\n## Before you call either\n\n### Deepgram Voice Agent API\n\n1. Set `mip_opt_out` in the Settings message to keep call audio out of training\n2. Use the function-call hold for anything irreversible, since replies can start before the user's turn is confirmed\n3. Back off exponentially on 429, a pay-as-you-go project gets 45 concurrent sockets\n4. Pin the LLM version, an unpinned Gemini route failed for 1.5 hours on 21 July 2026\n5. Mint browser tokens with `ttl_seconds`, not `ttl`, or they expire after 30 seconds\n\n### GPT-Live\n\n1. Create sessions on a server with the project API key. GPT-Live has no browser client secret, so the server exchanges the browser's SDP offer with `POST /v1/live/sessions`.\n2. Choose `delegation.type` at creation. Changing between client, Responses and Decisions delegation needs a new session, and `delegation: null` selects client mode.\n3. After `session.started`, listen for `error` with code `responses_validation_failed`. Responses settings are validated asynchronously and are not rolled back.\n4. Do not retry an outbound SIP `POST /v1/live/sessions` after a timeout. Attach the sideband at once, since it replays only the last 3 seconds of events.\n5. Keep the transport open until `session.closed` to read the final `usage.seconds`. A WebRTC session bills 15 seconds at creation, credited once it runs.\n\n## Questions\n\n### Which is better for AI agents, Deepgram Voice Agent API or GPT-Live?\n\nDeepgram Voice Agent API scores 68.1 (B) on agent readiness against GPT-Live's 66.8 (B), and leads in 5 of 7 scored categories. GPT-Live leads on reliability and agent ergonomics.\n\n### Do Deepgram Voice Agent API and GPT-Live need an API key?\n\nBoth need an API key.\n\n### Can an agent call Deepgram Voice Agent API and GPT-Live without installing anything?\n\nYes.
