ChatGPT语音模式开放模型选择：Pro可调用GPT-5.6 Sol与GPT-6 Astra
据AIbase报道，OpenAI语音产品经理Atty Eleti宣布ChatGPT语音模式升级，用户可在语音交互中选择模型与推理深度，Pro订阅用户可直接调用GPT-5.6 Sol或GPT-6 Astra，触发联网搜索或复杂推理时系统会自动切换到指定模型。官方称每次语音转文本模型处理都算作独立消息。同时GPT-Live日常限额被简化为四档：Go提供最多3小时GPT-Live-1mini且不再提供GPT-Live-1基础版，Plus最多3小时GPT-Live-1，100美元/月Pro最多15小时，200美元/月顶级Pro可无限使用GPT-Live-1；Plus与Pro配额用尽后不再自动降级到mini，原有Instant、Medium、High三档语音智能等级被取消。上述细节来自转述，未见官方公告佐证。
AI推荐理由 内容涉及ChatGPT语音模式可自由选择模型与推理深度、Pro订阅可调用GPT-5.6 Sol/GPT-6 Astra，以及GPT-Live配额分档调整和取消Instant/Medium/High三档，属于产品机制层面的具体变化，对AI应用与订阅用户有参考价值。但来源为AIbase转述，未提供官方公告链接或可验证证据，模型名称与配额细节无法独立核实，且正文含推广栏目与版权模板，信息密度被稀释，故质量分中等。

Atty Eleti, the product manager for OpenAI's voice products, officially announced that ChatGPT Voice has undergone a major feature upgrade. In this update, users can now freely choose their preferred model and reasoning depth during voice interactions. Subscribers to the Pro plan can directly access top-tier models such as GPT-5.6Sol or GPT-6Astra. When users trigger web searches or complex logical reasoning during conversations, the voice system will automatically switch to the specified powerful model to handle the relevant tasks.
To help users better understand the operational mechanism, the official stated that every time the voice mode transfers the user's voice conversation to the underlying text model for processing, this process is considered as sending an independent message to the model. With the full integration of the underlying large model, voice communication has become more intelligent, and it also puts forward new requirements for the overall quota mechanism.
With this upgrade in model capabilities, OpenAI has also fully simplified and optimized the daily usage limit rules for GPT-Live. The specific adjustment plan is divided into four tiers: the Go plan provides up to 3 hours of GPT-Live-1mini usage time, and no longer offers access to the basic version of GPT-Live-1; the Plus plan provides up to 3 hours of GPT-Live-1 usage time; the Pro plan at the $100 per month tier offers up to 15 hours of GPT-Live-1 usage time, while the top-tier Pro plan at $200 per month allows unlimited use of GPT-Live-1.
Notably, the platform has also made humanized adjustments to its benefit protection: when the voice quota of Plus and Pro users is exhausted, the system will no longer automatically downgrade to the lightweight GPT-Live mini. In addition, with the official implementation of the new mechanism, the original three independent voice intelligence levels "Instant, Medium, High" have officially been discontinued, marking a transition to a new era of interaction centered on free selection of large models and reasoning depth.
