How long does it take to develop a voice agent application prototype? 3 days? 5 days? OpenAI just shared a multi-level advanced AI agent developed based on the Realtime API, taking only 20 minutes!
OpenAI has publicly released the source code on GitHub. Although it is just a demo, it quickly surpassed 1200 stars, especially the extremely high development efficiency that surprised many veterans.

Realtime Agent Technical Features
The Realtime Agent provides efficient data interaction capabilities, responding immediately while the user is speaking, greatly reducing waiting time, while optimizing data transmission and processing flows, ensuring high efficiency and low latency, which is very important for developing voice agents.
Multi-level Collaborative Agent Framework provides a predefined agent flowchart, allowing developers to quickly configure and use. Each agent has clear responsibilities and tasks, ensuring tasks can proceed smoothly in the preset order, significantly reducing the time spent designing task flows from scratch.
The Realtime Agent also supports flexible task handover, allowing agents to seamlessly pass tasks, ensuring that each step can be handled by the most suitable agent, greatly improving the efficiency and accuracy of task processing.
State machine-driven task processing is another major technical highlight of the Realtime Agent. By using a state machine to break down complex tasks into multiple small steps, processing is done step by step. Each step has clear states and transition conditions, ensuring tasks can be completed sequentially and progressively.
At the same time, the state machine can monitor the execution status of tasks in real-time, adjusting based on user input and feedback. If a user encounters a problem at a certain step, the state machine can promptly adjust the task flow, provide assistance, or redirect the user.
Leveraging large models to enhance agent decision-making capabilities, when facing complex or significant task decisions, the Realtime Agent can automatically escalate tasks to smarter large models, such as OpenAI’s o1-mini. Developers can also choose suitable large models based on the specific needs of the tasks.
Clear visualized WebRTC interface, allowing users to select different scenarios and agents from a dropdown menu, viewing conversation records and event logs in real-time.
Provides detailed event logs and monitoring functions, offering developers powerful debugging and optimization tools. Detailed event logs record events from both the client and server. Developers can use these logs to monitor the execution status of tasks in real-time, quickly identifying and resolving issues.
Real-time monitoring can quickly identify agent performance bottlenecks for specific optimizations and adjustments. For example, if an agent’s response time is too long, task allocation can be promptly adjusted to ensure overall system performance.
Additionally, this Realtime Agent also draws on the well-known multi-level collaborative agent framework Swarm previously open-sourced by OpenAI, making it very reliable in terms of business execution and stability.
Some netizens expressed that two months ago, they spent 2-3 hours developing a real-time voice application. Of course, the Twilio API took a lot of time, but being able to create a minimum viable product (MVP) in under 20 minutes is truly astonishing.
In less than 20 minutes, building a voice application prototype using a multi-agent process… jaw-dropping.
