OpenAI GPT-5.6 Sol, Terra, Luna Launch Confirmed Thursday

OpenAI has confirmed the public launch of its new GPT-5.6 family of AI models for Thursday. This includes GPT-5.6 Sol, Terra, and Luna. The company announced the launch on social media, expanding preview access globally. OpenAI CEO Sam Altman also confirmed the release. This follows a delay due to concerns raised by the US government last month regarding the safety of advanced AI tools. The US government had requested a postponement of the full public release. OpenAI initially made the models available only to a small group of vetted partners. This allowed for discussions with Washington on safe AI model releases. GPT-5.6 Sol is the flagship model, designed to help identify and fix software flaws while avoiding cyberattack capabilities. Terra is a balanced, cost-effective model, and Luna is the fastest and most affordable for daily AI tasks. This launch aims to strengthen OpenAI's position against competitors.
