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**Pipecat.** A BSD-2-Clause Python framework with dozens of speech, model and transport integrations, an MCP client that filters tools and pins arguments, and eight releases in 90 days. It has no tool-approval step, and 1.12.0 can send OPENAI_API_KEY to other OpenAI-compatible providers when no key is passed, a flaw fixed on main but not yet released.\n\n## Before you call either\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### Pipecat\n\n1. Pass `api_key` explicitly to every OpenAI-compatible service such as Groq, Cerebras or OpenRouter. On 1.12.0 a missing key sends `OPENAI_API_KEY` to that provider\n2. Pass `tools_filter` to `MCPClient` so only the tools the call needs reach the model, and use `tools_arguments` for values the model must not choose\n3. Gate tools that book, pay or send in your own handler. Pipecat has no approval step, and a caller's speech goes straight to the model\n4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design\n5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs\n\n## Questions\n\n### Which is better for AI agents, GPT-Live or Pipecat?\n\nPipecat scores 68.9 (B) on agent readiness against GPT-Live's 66.8 (B), and leads in 5 of 7 scored categories. GPT-Live leads on security \u0026 auth.\n\n### Can an agent call GPT-Live and Pipecat without installing anything?\n\nGPT-Live has a hosted endpoint at https://api.openai.com/v1/live/sessions. No hosted endpoint is listed for Pipecat.\n\n### Are GPT-Live and Pipecat open source?\n\nNo open-source release is listed for GPT-Live. Pipecat is open source (BSD-2-Clause for the framework. Pipecat Cloud is a hosted service under Daily's terms of service).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/gpt-live-vs-pipecat.json, and with the fewest tokens: https://www.anchorterminal.com/compare/gpt-live-vs-pipecat.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"gpt-live\", \"b\": \"pipecat\"}`.
