Pricing

FreemiumDeepgram offers $200 in free credit on signup with no credit card required, usable across any service (Speech-to-Text, Text-to-Speech, Voice Agent API, and Audio Intelligence) and credits do not expire. Pay-As-You-Go pricing for Nova-3 starts at approximately $0.0043/minute for mono pre-recorded transcription (roughly $0.0052/minute for multi-channel/stereo audio) and $0.0077/minute for real-time streaming transcription, with rates dropping to around $0.003/minute at high volume. The Voice Agent API, which bundles speech-to-text, LLM orchestration, and text-to-speech, is priced at $4.50/hour, or roughly $0.08/minute (with a lower bring-your-own-LLM rate around $0.07/minute). Flux text-to-speech is free to use through September 12, 2026 (up to 45 concurrent streaming connections globally, 5 in EU/AU), with standard pricing applying starting September 13, 2026. A Growth tier offers roughly 15-20% discounted rates in exchange for a $4,000+ annual prepayment commitment. On-premise and self-hosted deployment for security, compliance, or latency-sensitive workloads requires a custom Enterprise agreement.

PaidLuma AI provides subscription-based access to AI video and image generation tools. Plans start at **$30/month** for individual creators, with higher-tier Pro ($90/month) and Ultra ($300/month) plans offering increased usage limits. Team and Enterprise options are available for businesses requiring collaboration, analytics, and custom AI solutions.

Deepgram Pros & Cons

Pros

Nova-3 delivers industry-leading accuracy with a 47-54% lower word error rate than competing models
Voice Agent API eliminates the need to stitch together separate STT, LLM, and TTS services
$200 free credit with no credit card required is one of the more generous evaluation tiers in the category
Billing by the exact second with transparent, published per-minute rates avoids hidden pricing surprises
Proven at massive scale: 50,000+ years of audio processed, 1 trillion+ words transcribed, used by NASA, Spotify, and Twilio

Cons

Growth tier discounted pricing requires a $4,000+ annual prepayment commitment
On-premise/self-hosted deployment requires a custom enterprise agreement rather than self-serve setup
Steeper learning curve than simpler transcription apps, built for developers rather than non-technical dashboard users
Multi-channel (stereo) audio transcription costs meaningfully more than mono per-minute rates
Flux TTS pricing shifts from free to standard rates after September 12, 2026, which teams building now should plan around
