gpt realtime model is for teams that need to build voice agents, speech demos and multimodal call flows from the browser. The workspace is browser-based so you can prototype and iterate without installing extra tools.

Latency is a focus, so conversations aim to feel immediate and natural. The platform also offers an API so you can connect the same capabilities into existing systems or backend services.

It’s presented as a freemium product and suits projects that need fast, interactive voice interfaces—customer service bots, educational voice tools or virtual assistants are all typical uses.
