Which functionality allows users to interactively refine their input in Bing Chat?

The functionality that allows users to interactively refine their input in Bing Chat is real-time feedback. This feature enables users to receive immediate responses and suggestions based on their queries, allowing them to adjust their inputs dynamically. This interaction helps in fine-tuning the conversation, making it more engaging and responsive to the user's needs.

While editing messages and quick reply options may enhance the user experience by allowing modifications or quick responses, they do not specifically facilitate the interactive refinement of input as effectively as real-time feedback does. Organizing chat history contributes to better navigation of past interactions but doesn't directly impact the refining process of current inputs. Real-time feedback is crucial for creating a fluid conversation where users feel empowered to shape their inquiries and receive tailored assistance.
