Pricing
PaidAmazon Rekognition uses pay-as-you-go pricing with no upfront commitment across four usage categories. Image analysis: Group 1 APIs (face search/compare/index) and Group 2 APIs (labels, moderation, text, celebrities) are billed per image on a tiered scale starting at $0.0010 per image for the first million images per month, dropping to $0.0004 per image at higher volumes; Image Properties is billed separately starting at $0.00075 per image. Face metadata storage costs $0.00001 per face or user vector per month. Video analysis: stored video is billed per minute (for example $0.10/min for Label Detection, $0.05/min for Shot Detection), while streaming video events cost around $0.00817 per minute processed. Custom Labels charges $1 per training hour and $4 per inference hour (inference must be manually deprovisioned to stop billing). Face Liveness checks start at $0.015 per check for the first 500,000 checks per month, decreasing at higher volumes. Custom Moderation adds $5 per training hour plus a tiered per-image inference cost starting at $0.0012 per image. New AWS accounts get a 12-month Free Tier (1,000 images/month, 60 video minutes/month, 2 free training hours) plus up to $200 in AWS Free Tier credits.
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.

Summary
AWS's deep learning API for image and video analysis, face recognition, and content moderation
Voice AI infrastructure for speech-to-text, text-to-speech, and voice agents
AWS Rekognition Pros & Cons
Pros
- Pay-as-you-go pricing with no minimum fees or upfront commitment, and a genuinely useful 12-month free tier
- No machine learning expertise required to add production-grade computer vision to an application
- Broad feature set covering faces, labels, text, moderation, and custom object detection in one service
- Custom Labels can train a usable model from as few as 10 to 20 images via AutoML
- Deep integration with the AWS ecosystem, including S3, Kinesis Video Streams, and Lambda
- Scales automatically from small projects to millions of images or hours of video per month
Cons
- Pricing can scale quickly for high-volume use cases (millions of images or hours of video per month), requiring careful cost modeling
- Requires an AWS account and familiarity with the AWS console, IAM permissions, and SDKs, which adds setup overhead for non-AWS users
- Face recognition and identity verification features raise privacy and compliance considerations, especially for biometric data in regulated regions
- Custom Labels training and inference are billed hourly even when idle unless resources are manually deprovisioned
- No built-in low-code interface for non-developers — it is API-first and expects a technical integration
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
