Introduction
A browser-based workspace for testing and refining realtime voice AI agents before launch.
What is GPT Realtime 2?
GPT Realtime 2 is a web-based platform designed for developing and testing realtime voice AI applications. It addresses a common challenge for developers and product teams: how to prototype and evaluate speech-to-speech interaction and conversational AI flows without writing extensive production code first. The tool provides a dedicated workspace for planning, executing, and reviewing live low-latency audio sessions, where spoken input is processed and answered with contextual spoken responses. It is particularly suitable for teams building voice-first applications like customer support agents, interactive tutors, or sales demos, allowing them to iterate on prompts, test tool-ready workflows, and review session quality in a controlled environment before committing to full-scale integration.
Key Features of GPT Realtime 2
Prompt Control
Users can define the AI agent's persona, conversational boundaries, goals, and response style in a single, centralized prompt, enabling precise tuning of the agent's behavior for different scenarios.
Realtime Voice Testing
The platform facilitates live testing of low-latency audio exchanges, allowing teams to evaluate critical elements like greeting effectiveness, pacing, interruption handling, and pronunciation clarity in a realistic flow.
Tool-Ready Workflow Planning
Teams can design conversations that incorporate function calls, app actions, data collection, and human handoffs, making it easier to prototype complex, app-ready conversations within one agent brief.
Comprehensive Review Workflow
After a session, users can review detailed transcripts, add notes, and use scorecards to compare the quality and performance of different prompt versions, creating a structured feedback loop.
Session Output and Export
Every test session can be recorded, with outputs like transcripts and audio available for download, turning prototype tests into practical documentation and launch notes for engineering teams.
Use Cases for GPT Realtime 2
Voice Support Agent Development
Teams can prototype and test AI-powered customer support agents, simulating realistic troubleshooting conversations to refine response accuracy and escalation protocols.
Interactive Tutoring and Training
Educators and trainers can build conversational practice scenarios for language learning or role-play simulations, using the realtime voice AI to provide immediate, spoken feedback.
Product Demo and Sales Assistant Creation
Developers can create interactive, voice-guided product demos or sales assistants to engage potential customers, testing the flow and persuasive power of the script in a live setting.
Internal Tool Prototyping
Companies can quickly prototype voice interfaces for internal tools, such as data lookup systems or procedural guides, to assess usability and efficiency before development.
How to Use GPT Realtime 2
Using GPT Realtime 2 involves a straightforward three-step process to go from an idea to a testable agent.
- Enter Your Prompt: Begin by typing a clear, detailed prompt into the workspace. This should define the agent's role, the task, and any specific rules for the conversation.
- Configure Session Settings: Adjust the available settings for your test. This may include selecting voice parameters or configuring specific tool-ready workflows you want to simulate during the session.
- Run and Review the Session: Start the live speech-to-speech interaction. Speak to the agent and evaluate its responses in real-time. Afterward, save the session, review the transcript, and export any useful outputs for further analysis.
Target Audience for GPT Realtime 2
- AI Developers and Engineers building conversational AI products.
- Product Managers and Founders validating voice AI concepts before full development.
- Customer Support Teams designing and testing automated support flows.

GPT Realtime 2's Pros and Cons
| Aspect | Pros | Cons |
|---|---|---|
| Development Speed | Accelerates prototyping by allowing realtime voice AI testing without backend coding. | Primarily a prototyping tool; teams still need to build the final production integration. |
| Testing Fidelity | Enables realistic testing of low-latency audio and natural conversation flow. | The test environment may not perfectly replicate all conditions of a live production app. |
| Collaboration | Facilitates team review with shared transcripts, notes, and scorecards. | Requires stakeholders to be familiar with AI prompt concepts to provide effective feedback. |
| Workflow Planning | Excellent for designing tool-ready workflows and complex conversation logic upfront. | May have a learning curve for teams new to designing structured AI agent interactions. |
