AssemblyAI added a new Sync Speech-to-Text API priced at $0.45/hr — its seventh distinct priced product surface. The Sync API returns a finished transcript in a single synchronous API call: you POST a short clip and read the transcript off the response, with no polling, WebSocket, or job to manage.
It delivers Universal-3.5 Pro accuracy, processes up to 2 minutes per request with roughly 134 ms p50 latency, and includes per-word timing and confidence across 18 languages. The $0.45/hr rate matches Universal-3.5 Pro Realtime, reflecting the low-latency infrastructure. All other rates are unchanged: async transcription ($0.15/hr Universal-2, $0.21/hr Universal-3.5 Pro), realtime streaming ($0.15-$0.45/hr), and the Voice Agent API ($4.50/hr).
