Deepgram Cuts Voice Agent API Rates, Triples Concurrency Limits
What happened
Between the Dec 29, 2025 and Mar 30, 2026 captures of Deepgram's pricing page, Pulse recorded 3 changes: Concurrency limits increased for STT WSS (50->150/225), TTS REST+WSS (15->45/60), and Voice Agent API WSS (15->45/60) for Pay As You Go and Growth plans respectively; Voice Agent API prices changed across all tiers: Standard PAYGO $0.0800->$0.075, Custom-BYO LLM PAYGO $0.0700->$0.056, Advanced PAYGO $0.1600->$0.163. Enterprise column removed from pricing table; Smart Formatting added as an explicit Speech-to-Text add-on feature, now shown as Included for both Pay As You Go and Growth plans. Previously only mentioned in feature description text. Pulse files it as a packaging change (limit increase, package change, feature added) with an upward direction. Pulse's latest capture (Sep 21, 2026) lists Growth at $333.33 and Pay As You Go at $0 per 1,000 input tokens (Audio Intelligence) + $0.01 per minute (STT Flux English pre-recorded).
It lands 46 days after Deepgram's previous change, "Deepgram triples concurrency limits across all API tiers" (Feb 16, 2026). Before that Pulse recorded "Deepgram Introduces New Flux Model Pricing: $0.0077/min for Pay As You Go and $0.0065/min for Growth Plan After Free Promotional Period Ends" (Jan 11, 2026). Deepgram has been tracked since 2023-11-14.
