AssemblyAI launches Voice Agent API and restructures pricing into six product tabs
AssemblyAI added a Voice Agent API at $4.50/hr ($0.075/min), broke Guardrails out as a priced family, and reorganized its pricing page into six product tabs while keeping async rates flat.
Pricing page grouped async ($0.15/$0.21/hr), streaming (incl. Whisper-Streaming $0.30/hr) and Speech Understanding add-ons; no standalone Voice Agent product.
Six product tabs: Pre-recorded STT, Realtime STT, Voice Agent ($4.50/hr / $0.075/min), Speech Understanding, Guardrails, LLM Gateway. Realtime swaps Whisper-Streaming for Universal-Streaming Multilingual ($0.15/hr); Medical Mode and Keyterms/Prompting add-ons added; async unchanged.
AssemblyAI reorganized its pricing page into six product tabs and shipped a standalone Voice Agent API priced at $4.50/hr ($0.075/min) — a proprietary end-to-end voice stack built on its Realtime Speech-to-Text API.
Base async transcription rates are unchanged (Universal-2 $0.15/hr, Universal-3.5 Pro $0.21/hr). The realtime lineup dropped Whisper-Streaming and added Universal-Streaming Multilingual ($0.15/hr) alongside Universal-3.5 Pro Realtime ($0.45/hr). Guardrails is now a distinct priced family (Profanity Filtering $0.01/hr, PII Audio Redaction $0.05/hr, PII Text Redaction $0.08/hr, Content Moderation $0.15/hr), and pre-recorded add-ons gained Medical Mode ($0.15/hr) and Keyterms Prompting / Prompting ($0.05/hr). The LLM Gateway now surfaces explicit per-model token rates (e.g. GPT-5.5 $5/$30 per 1M, Claude 4.8 Opus $5/$25 per 1M).
