OpenAI to publicly release GPT-5.6, rolls out conversational AI models

OpenAI is publicly releasing its GPT-5.6 models (Sol, Terra, and Luna) after initially limiting access to a small group of trusted partners at the U.S. government's request. The company also announced GPT-Live, a new generation of voice models that can listen and speak simultaneously, making conversations feel more natural. OpenAI stated it believes in broad access to AI tools and is working with the government to develop a repeatable evaluation process for future model releases.
