## The update

OpenAI has recently upgraded the functionality of ChatGPT Voice Mode. This update grants users greater control by allowing them to select the model and reasoning intensity during voice interactions. Pro subscribers can now switch between GPT-5.6 Sol and GPT-6 Astra to suit different usage scenarios. When conversations involve web search requirements or complex logical reasoning, the system automatically activates the user-selected model to complete the task. It is important to note that each instance of transferring a voice request to the underlying text model for processing counts toward the user's message quota. This mechanism ensures transparency in resource usage while reminding users to monitor their quota consumption when using advanced models for deep reasoning.
