  "account": "OpenAI has announced the launch of two new GPT-6 models, Sol and Luna, expanding on the capabilities of their previous GPT-6 model, Astra. These new models are designed to provide more cost-efficient performance for coding and other tasks.\n\nGPT-6 Sol and Luna are cheaper than their GPT-5.6 predecessors, with Sol being 50% less expensive. They offer advancements in coding, factuality, computer use, and alignment, making them more suitable for professional work. GPT-6 Sol is particularly well-suited for complex coding and agentic workflows, while Luna is ideal for high-volume tasks.\n\nFree and Go users can access Luna in the desktop app, while GPT-6 Sol and Luna are available in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu users. Enterprise administrators must enable the new models.\n\nOpenAI expects to discontinue the medium model GPT-6 Terra in favor of the three GPT-6 models: Terra, Sol, and Astra. This expansion of the GPT-6 universe aims to make advanced AI more accessible and practical for a wider range of everyday tasks and applications at scale.",
