An OpenAI ChatKit client is a lightweight, embeddable frontend component that connects end users to conversational agents built with OpenAI. It provides a complete chat interface—including message rendering, input handling, loading states, and UI controls—while securely communicating with an OpenAI-backed agent or workflow.

The ChatKit client abstracts the complexity of agent interaction by managing conversation state, prompt submission, streaming responses, and error handling behind a consistent UI. It supports configuration for predefined prompts, branding, icons, and behavioral options, allowing teams to tailor the chatbot experience without modifying core logic.

Designed for flexibility and scalability, the OpenAI ChatKit client can be embedded into web applications or static pages via a simple script inclusion. This enables rapid deployment across multiple environments and use cases while maintaining a consistent user experience. By separating agent logic (defined in OpenAI Agent Builder) from the client UI, the ChatKit client ensures clean boundaries between frontend presentation and AI-driven behavior, making it suitable for enterprise-grade, multi-tenant chatbot deployments.
