Customer Experience Agent Studio is Generally Available

Customer Experience Agent Studio (CX Agent Studio) is now Generally Available (GA). This unified platform, powered by Gemini, simplifies the creation of high-quality customer experience agents. This launch includes agents-building-agents capabilities, featuring "Start with AI," which lets developers instantly generate a starter agent and tools by providing documents and high-level instructions. This launch also delivers multimodal excellence, combining high-fidelity native audio models for natural voice personas with an out-of-the-box configurable chat messenger that supports rich multimodal interactions and customizable widgets. CX Agent Studio provides a secure, enterprise-ready environment to rapidly build, improve, and monitor your AI workforce.

Capabilities:

• Start with AI: Accelerate development by using generative AI to build a starter agent and associated tools automatically. Simply provide your existing documentation and a set of instructions, and the platform handles the initial setup.
• Configurable chat messenger: Deploy a fully functional, web-based client "out of the box" that supports text, voice, and multimodal interactions.
• Rich content widgets: Customize the user experience with configurable widget templates (including product carousels, order trackers, and quick actions) to fit your brand needs.
• Easy deployment: Embed the messenger into your web or mobile application with a simple HTML snippet generated directly from the Deploy tab.
• Flexible authentication: Secure your agent with built-in support for both Token Brokers (service account-based) and OAuth 2.0 (user-based) authentication flows.
• Native audio models: Create natural, brand-specific voice personas with high-fidelity audio models (powered by Chirp 3) designed to handle complex conversations with ease.
• Enterprise connectors: Seamlessly integrate with essential business tools using pre-built connectors
• Enterprise-grade security: Ensure that your data remains secure with robust identity management and compliance standards.
