OpenAI is revamping its most-used model in ChatGPT, GPT-5.5 Instant, to enhance conversation quality. The updated model now better understands users’ underlying goals and adapts to clarifications. It also excels at local business queries, providing more coherent and less templated responses. This improvement aims to deliver more human-like interactions, making ChatGPT more effective for decision-making and advice-seeking. Why it matters: This update signals a significant step forward in AI’s ability to engage in natural, goal-oriented conversations that can rival human interactions.
