Together AI Launches Unified Voice Agent Cloud With Full Pipeline Co-Location

Together AI

Mar 18, 2026 · Updated Apr 25, 2026

Together AI launched a unified platform for real-time voice agents with STT, LLM, and TTS co-located on one cloud. Most voice stacks route audio across separate vendors — Together keeps all three in the same cluster, hitting latency under 700ms.

Together AI, the AI Native Cloud, launched a unified solution for building real-time voice agents — co-locating STT, LLM, and TTS in the same infrastructure cluster. The platform natively hosts Cartesia (real-time TTS: Sonic-3, Sonic-2) and Deepgram (speech recognition and synthesis), alongside Whisper, Minimax Speech, Rime, and Kokoro. Teams get one API, one billing surface, and can swap models across the full stack without rebuilding integrations. Enterprise tiers include SOC 2 Type II, HIPAA, and dedicated data residency.

Multi-vendor voice stacks route audio and text across the public internet at every handoff — adding latency and complexity. Running the full pipeline on local datacenter networking, Together delivers end-to-end latency under 700ms for natural turn-taking. The modular design preserves intermediate transcripts, giving teams data-routing control that opaque speech-to-speech systems don't offer.

Configure your preferred STT, LLM, and TTS models from Together's catalog and swap them independently as your requirements evolve.
