Assemblyai adds FAQ clarifying Voice Agent API's flat $4.50/hr rate
What happened
Between the Aug 17, 2026 and Aug 24, 2026 captures of Assemblyai's pricing page, Pulse recorded one change: New FAQ entry added asking what's included in the Voice Agent API's flat $4.50/hr rate. The question is newly visible in OCR; the detailed 'included features' answer text is markdown-only and not painted on screen. Pulse files it as a product change (positioning) with a neutral direction. The current page lists Voice Agent API at $4.5 per hour + $4.5 per hour, Universal-3 Pro at $0.21 per hour of audio, Universal-Streaming Multilingual at $0.15 per hour of audio, Universal-3 Pro Streaming at $0.45 per hour of audio and Universal-2 at $0.15 per hour of audio.
It lands 49 days after Assemblyai's previous change, "AssemblyAI renames Universal-3.5 Pro, adds 18-language diarization support" (Jul 6, 2026). Before that Pulse recorded "Assemblyai upgrades realtime STT to Universal-3.5 with 18-language support" (Jun 29, 2026). Assemblyai has been tracked since 2023-11-14.
In the same window Deepgram, Otter, IBM and Google Cloud also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
