Pricing
PaidReplicate uses per-second, pay-as-you-go billing with automatic scale-to-zero when idle. Compute pricing includes CPU at $0.000100/sec, Nvidia T4 GPU at $0.000225/sec, Nvidia L40S GPU at $0.000975/sec, 2x Nvidia L40S GPU at $0.001950/sec, Nvidia A100 (80GB) GPU at $0.001400/sec, and 8x Nvidia A100 (80GB) GPU at $0.011200/sec. Many popular models also have their own flat per-run or per-image pricing (for example, some image models start around a few tenths of a cent per generation). There is no separate free tier beyond initial signup credits, and Enterprise plans with custom pricing, dedicated support, and higher scale are available by contacting the Replicate team.
FreemiumInworld AI uses a credit-based subscription model with a free On-Demand tier for evaluation and prototyping, including up to 70 minutes of TTS or 400 minutes of STT at no cost, with 100 custom voices and full Realtime API access under a commercial license.
Paid plans start with Creator at $25/month (up to 33% off base rates), Builder at $100/month (up to 40% off, workspace sharing), Developer at $300/month (up to 47% off, priority email support), and Growth at $1,500/month (up to 53% off, 30,000 custom voices, HIPAA and BAA add-ons). Realtime TTS-2 pricing ranges from $25 per million characters on-demand down to $12.50 on the Growth plan, with Realtime TTS-2 Flash starting at $15 and falling to $7.
Enterprise pricing is fully custom, with Realtime TTS-2 rates as low as $5 per million characters, price-match guarantees, SLAs, EU and India data residency, and a dedicated account manager. Unused subscription credits roll over for up to 3 months, and LLM usage through the Realtime Router is billed at provider cost with no markup.

Summary
Run, fine-tune, and deploy AI models with one line of code
Realtime TTS, STT, and LLM routing infrastructure for consumer-scale voice AI
Replicate Pros & Cons
Pros
- One-line API access to thousands of production-ready open-source models
- True pay-per-second billing with automatic scale-to-zero when idle
- Cog makes packaging and deploying custom models straightforward for developers
- Fine-tuning support lets teams personalize existing models with their own data
- Backed by major investors including a16z, Sequoia, and Nvidia's NVentures
- Now integrated with Cloudflare's global edge network following its 2026 acquisition
Cons
- Per-second GPU billing means costs can be harder to predict than flat per-token model pricing
- Community-contributed models vary in documentation quality and long-term maintenance
- Now part of Cloudflare following its 2026 acquisition, which may bring platform or roadmap changes over time
- Custom model deployment via Cog has a learning curve for developers new to containerized ML packaging
- Cold-start latency can occur on lower-traffic models before scaling kicks in
Inworld AI Pros & Cons
Pros
- Realtime TTS consistently ranks #1 on the Artificial Analysis Speech Arena in blind user tests
- Significantly cheaper than comparable providers like ElevenLabs and Deepgram at scale
- Single API and WebSocket connection covers STT, LLM routing, and TTS together
- Provider-agnostic LLM routing avoids vendor lock-in and lets teams swap models anytime
- Enterprise-grade compliance built in, including SOC 2 Type II, HIPAA, and GDPR
Cons
- Full pricing benefits require higher-tier paid plans, which may be costly for very small projects
- Advanced compliance features like HIPAA, BAA, and zero data retention are gated behind add-ons or Enterprise
- Professional voice cloning is only available from the Developer plan and above
- Some capabilities like WebRTC and SIP transport are still in early access rather than general availability
