ElevenLabs Agents
- +LLM-agnostic on top of best-in-class proprietary text-to-speech and its own speech-to-text
- +Strong first-class telephony story (Twilio, SIP, multiple carriers) with sub-second latency
- +Flexible build paths: no-code builder, SDKs, WebSocket API, function calling, and MCP
- -Layered, recently changed pricing (bundled minutes plus overage plus pass-through LLM cost) makes total cost hard to predict
- -Autonomy is bounded to configured tools, not autonomous out of the box
Retell AI
- +Provider-flexible: bring your own telephony, voices, and LLM, or use Retell's built-in carrier
- +Structured Conversation Flow Agents (nodes and transitions) give fine control alongside looser prompt-based agents
- +Usage-based pricing with no mandatory base subscription and free credits to start; built-in testing and monitoring
- -Advertised $0.07/min covers only the voice engine; LLM, telephony, and international add to real per-minute cost
- -Building reliable structured flows for complex calls takes meaningful human setup
