About AssemblyAI
AssemblyAI ships a full voice-agent pipeline and a multi-LLM gateway, moving past speech-to-text.
AssemblyAI's recent shipping is dominated by two themes. The first is the new Voice Agent API — a complete pipeline (speech understanding, LLM reasoning, voice generation) over a single WebSocket at a flat $4.50/hour, running on Universal-3 Pro Streaming. The second is the LLM Gateway maturing as a hosted multi-LLM proxy: Claude Opus 4.7 is now available through it, and automatic model fallbacks landed in public beta. Around these, smaller releases include same-request unredacted transcripts on PII Redaction, Universal-2 accuracy improvements for Hebrew and Swedish, and a Medical Mode add-on for streaming transcription.
