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.
FreemiumUnity Personal Edition users can start a 14-day free trial that grants 1,000 AI credits one-time; after the trial, the in-editor assistant converts to a $10/month subscription for 1,000 credits per month, with additional credit bundles purchasable separately if needed. Unity Pro, Enterprise, and Industry subscribers automatically receive assistant access and credits included in their existing paid seats at no extra cost, simply by installing the assistant package and assigning seats in the organization dashboard. The AI Gateway does not consume Unity credits when connecting a third-party AI subscription, and the MCP Server is entirely free with no concurrency limits and requires no AI tools subscription at all, on any tier.

Summary
Voice AI infrastructure for speech-to-text, text-to-speech, and voice agents
Unity's in-editor agentic assistant, AI gateway, and MCP server for game development (successor to Unity Muse)
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
Unity AI Tools Pros & Cons
Pros
- In-editor assistant is trained specifically on Unity workflows, not a general-purpose model bolted on afterward
- Project-aware context lets the assistant inspect and act on actual scene objects and components
- MCP Server and AI Gateway are both free with no concurrency limits, regardless of subscription tier
- Flexibility to bring your own third-party AI model/subscription instead of relying solely on Unity's system
- Full user control: undo support, AI-generated asset tagging, and granular permission settings
- Pro, Enterprise, and Industry subscribers get the assistant bundled into existing seats at no added cost
Cons
- Still in beta, so features, pricing, and stability are subject to change before general availability
- Requires Unity 6.0 or newer; the MCP server integration is not backwards compatible with older Unity versions
- Personal Edition users only get a one-time 1,000-credit trial before needing to pay $10/month, unlike Pro/Enterprise seats where it's bundled in
- Replaces the previous Unity Muse product, so any workflows, prompts, or assets built around Muse's first-party models will need to be rebuilt
- As a third-party-model-based system, output quality and behavior depend partly on which underlying AI model a developer chooses via the AI Gateway
