# Introduction

> A quick overview of Rime's speech platform: the default model, deployment options, enterprise features, pricing, and the developer surfaces you build on.

Rime is voice AI **made for human conversation**: natural, low-latency speech for production voice agents, IVR, and telephony.

Its flagship model, Coda, is trained on full-duplex conversations between real people, not voice actors or audiobook narrators. Coda has top-rated voice quality in human evaluations and runs at sub-100ms model latency. The cloud API offers 287 Coda voices across 9 languages. Coda can also run in your VPC or fully on-premises, where the packaged language set may differ.

## Rime at a glance

| Area                        | Summary                                                                                                                                                                                           |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Product**                 | Low-latency neural text-to-speech. The flagship model, Coda, reaches sub-100ms model latency (sub-200ms end to end over the cloud API).                                                           |
| **Reach**                   | 500+ voices across the model lineup, including 287 Coda voices across 9 languages, plus instant custom voice cloning.                                                                             |
| **Deployment**              | Regional cloud API, virtual private cloud (VPC), or on-premises with Docker Compose or Kubernetes.                                                                                                |
| **Enterprise**              | Unlimited concurrency, unlimited custom voice clones, SLAs, and dedicated support.                                                                                                                |
| **Security and compliance** | SOC 2 reports and a HIPAA Business Associate Agreement (BAA). VPC and on-prem keep audio and text inside your own network.                                                                        |
| **Pricing**                 | Usage-based. Starter is \$0.05 per 1,000 characters with 3,000 free minutes and 20 concurrent streams. Enterprise uses custom volume pricing. See [rime.ai/pricing](https://www.rime.ai/pricing). |

## Start with Coda

Coda is the default model for new projects. Set `modelId: coda` explicitly so the API uses Coda rather than the Mist v3 fallback.

Coda pairs an LLM backbone with a dedicated speech inference engine trained on full-duplex conversations between real people. Through the cloud API, it serves nine languages: English, Arabic, French, German, Hindi, Italian, Japanese, Portuguese, and Spanish. Each voice serves one of them, so the language you need determines which voices are available to you.
