Building a voice AI agent means stitching together 3-5 different model providers — Deepgram for STT, OpenAI for LLM, ElevenLabs for TTS — each with different APIs, auth, billing, latency profiles, and failure modes. A unified model interface lets you swap any model in the pipeline without changing your agent code. This is how we built it and why it matters for production voice AI.
