It is one day old, English only, installs from Git rather than PyPI, has no CI or changelog, and its accuracy figures are the author's own.\n\n**Deepgram Voice Agent API.** $0.075 a minute all in on Standard, $0.050 with your own LLM and TTS, $200 of credit with no card. No phone numbers or SIP, so you bridge Twilio or another carrier yourself.\n\n## Before you call either\n\n### CueLight\n\n1. Feed 320 float32 samples at 16 kHz mono per `push`. Resample first, or the call raises an AssertionError\n2. Spell the preset as `snappy` or `careful`. Any other name silently uses default thresholds\n3. Call `clear()` before a new call or session. Pass `reset_on_turn_start=False` if your pipeline already resets per turn\n4. Pin weights by downloading them to a local folder and passing that path to `from_pretrained`\n5. Don't use it to identify speakers or clone voices. The training data's conditions forbid it\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## Questions\n\n### Which is better for AI agents, CueLight or Deepgram Voice Agent API?\n\nDeepgram Voice Agent API scores 68.1 (B) on agent readiness against CueLight's 48.8 (D), and leads in 6 of 7 scored categories. CueLight leads on payments \u0026 pricing.\n\n### Can an agent call CueLight and Deepgram Voice Agent API without installing anything?\n\nNo hosted endpoint is listed for CueLight. Deepgram Voice Agent API has a hosted endpoint at https://agent.deepgram.com/v1/agent.\n\n### Are CueLight and Deepgram Voice Agent API open source?\n\nCueLight is open source (Apache-2.0).
