What does Inworld do?

Inworld is a platform for developers to build and deploy real-time AI characters. It provides the infrastructure to create interactive, voice-enabled agents for applications like video games, customer support, and AI companions. The core of the platform is a high-performance text-to-speech engine and an orchestration layer that manages large language models with low latency.

The tool stands out with its focus on real-time performance. Its TTS-1.5 model claims to be the top-ranked for real-time latency, generating speech in under 200 milliseconds. For building character behaviors, Inworld offers a visual graph system and model-agnostic routing, letting developers connect different AI models. This allows for scalable deployment across hosted, on-premise, or on-device environments.

Game developers benefit most, using Inworld to create dynamic non-player characters that can converse naturally. It's also used by companies building AI support agents to handle customer queries and by app developers creating interactive AI companions. The platform is designed for applications where immediate, natural-sounding interaction is key.
