Assemblyai unifies audio limits with expanded 333h free allowance
What happened
Between the Mar 30, 2026 and Apr 6, 2026 captures of Assemblyai's pricing page, Pulse recorded one change: Free plan pre-recorded audio limit increased from 185h to 333h; separate pre-recorded and streaming limits consolidated into one unified 333h allowance for pre-recorded or streaming audio. Pulse files it as a packaging change (limit increase) with an upward direction. Pulse's latest capture (Aug 24, 2026) 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 8 days after Assemblyai's previous change, "Assemblyai Launches Medical Mode for Healthcare Transcription" (Apr 1, 2026). Before that Pulse recorded "Assemblyai cuts flagship STT price 22% with Universal-3 Pro rebrand" (Apr 4, 2026), "AssemblyAI adds Claude 4.6 Sonnet, Opus models to LLM Gateway" (Mar 16, 2026) and "Assemblyai launches Universal-3 Pro Streaming at $0.45/hr for voice agents" (Mar 10, 2026). Assemblyai has been tracked since 2023-11-14.
