OpenAI's new GPT-Live models talk back in real time

OpenAI released GPT-Live-1 and GPT-Live-1 mini, a generation of full-duplex voice models that can listen and speak at the same time, adding natural touches like a quick "mhmm" or staying quiet while you think. They now power ChatGPT Voice globally, replacing Advanced Voice Mode, and lean on GPT-5.5 behind the scenes for harder questions.

Why it matters: Fluid, interruption-friendly voice could finally make talking to an assistant feel like a real conversation rather than a walkie-talkie exchange.

An electric field triples how fast heat moves through a ceramic

Researchers showed that switching on an electric field can boost heat conduction in a class of ceramics called relaxor ferroelectrics by nearly 300%, by aligning tiny charges so that heat-carrying vibrations scatter less and travel farther. Earlier attempts had managed only 5 to 10%.

Why it matters: Being able to dial heat flow up or down on demand could unlock far more efficient cooling for electronics and energy systems.
