OpenAI Releases New Voice Model GPT-Live and Lifts Restrictions on GPT-5.6 Sol : OpenAI has officially launched GPT-Live, a next-generation voice model based on a full-duplex architecture that supports simultaneous listening and speaking, moving away from the turn-based walkie-talkie mode. For complex tasks, the system automatically delegates processing to GPT-5.5 in the background, significantly boosting reasoning and search capabilities. Meanwhile, the official access restrictions on GPT-5.6 have been lifted, with the official release of three models—GPT-5.6 Sol, Terra, and Luna—announced for Thursday, focusing on extreme reasoning. Leaks suggest that OpenAI has completely abandoned the 4T-parameter Spud base and will accelerate the release of GPT-6 based on a brand-new large base as early as this month to counter competition from Anthropic.
