  "account": "OpenAI has introduced two new models in its GPT-6 family, GPT-6 Sol and GPT-6 Luna, offering 50% lower API costs compared to their GPT-5.6 counterparts. These new models incorporate features from the flagship GPT-6 Astra model, enhancing their coding, factual accuracy, computer use, and professional work capabilities. GPT-6 Sol is designed for complex tasks like coding and AI agents, while GPT-6 Luna targets high-volume tasks such as document summarization, information extraction, and quick responses. The pricing reductions are attributed to efficiency improvements in caching and inference. GPT-6 Sol delivers significant improvements in coding performance, with a notable 33.2% increased efficiency over GPT-5.6 Sol on the FrontierCode 1.1 benchmark. It also shows half the error rate of GPT-5.6 Sol in real-world conversations. Meanwhile, GPT-6 Luna offers lower costs and faster execution while maintaining comparable performance to Claude Opus 5 on the OSWorld 2.0 benchmark. Both models are now accessible through ChatGPT Work, Codex, and the OpenAI API, with Luna also becoming available for Free and Go users via the ChatGPT desktop app.",
