On July 9 (local time), OpenAI announced the global availability of its latest GPT-5.6 series models, marking the end of the limited preview phase previously restricted to a select group of trusted partners. The series includes the flagship model GPT-5.6 Sol, the balanced model GPT-5.6 Terra, and the lightweight, cost-effective model GPT-5.6 Luna. Sol supports Ultra mode, enabling the coordination of four AI agents to handle complex tasks in parallel, enhancing efficiency in scenarios such as code development, scientific research, and cybersecurity. The GPT-5.6 series leads in multiple benchmark tests while reducing inference costs and response times, and is equipped with a comprehensive safety protection system, supporting programmatic tool invocation.
