A professional community focused on AIGC, following the development and application of large language models (LLMs) like Microsoft & OpenAI, Baidu Wenxin Yiyan, and iFlytek Spark, with a focus on market research and the AIGC developer ecosystem. Welcome to follow!
How long does it take to develop a prototype application for a voice AI agent? 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 made the source code publicly available on GitHub. Although it is just a demo, it quickly surpassed 1200 stars, especially the high development efficiency that surprised many veterans.

Real-time Agent Technical Features
The real-time Agent can provide efficient data interaction capabilities, responding immediately while the user is speaking, greatly reducing waiting time, optimizing data transmission and processing flows, ensuring high efficiency and low latency, which is crucial for developing voice AI agents.
Multi-level Collaborative Agent Framework provides a predefined Agent flowchart, allowing developers to quickly configure and use it. Each Agent has clear responsibilities and tasks, ensuring that tasks proceed smoothly in the preset order, significantly reducing the time spent designing task flows from scratch.
Real-time Agents also support flexible task handover, allowing Agents to seamlessly transfer tasks, ensuring that each step is handled by the most suitable Agent, greatly improving task processing efficiency and accuracy.
State machine-driven task processing is another major technical highlight of the real-time Agent. By using a state machine to break complex tasks into smaller steps, tasks are processed 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 an issue 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 faced with complex or critical task decisions, the real-time Agent can automatically escalate tasks to more intelligent large models, such as OpenAI’s o1-mini. Developers can also select suitable large models according to the specific needs of the task.
Clear visual WebRTC interface, allowing users to select different scenarios and Agents from a dropdown menu, and view conversation records and event logs in real-time.
Providing detailed event logs and monitoring capabilities, offering developers powerful debugging and optimization tools. The 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 promptly identify Agent performance bottlenecks for specific optimization and adjustments. For example, if an Agent’s response time is too long, task allocation can be adjusted in a timely manner to ensure overall system performance.
Additionally, this real-time Agent also draws from the previously open-sourced famous multi-level collaborative Agent framework Swarm by OpenAI, making it very reliable in terms of business execution and stability.
Some netizens noted that two months ago, they spent 2-3 hours developing a real-time voice application. Of course, Twilio API took quite some time, but creating a minimum viable product (MVP) in under 20 minutes is truly astonishing.
In less than 20 minutes, using a multi-Agent process to build a voice application prototype… jaw-dropping.
