OpenAI GPT 5.6: Soul, Terra, Luna Models & ChatGPT Work

OpenAI has launched its GPT 5.6 series of models, featuring Soul, Terra, and Luna. These models are designed to handle complex agent workflows, everyday tasks, and high-frequency, low-cost tasks. Alongside these models, OpenAI also introduced ChatGPT Work, a new desktop app, and Hosted Sites. These tools aim to create a complete system for task entry, environment integration, and result delivery. The Soul model focuses on complex planning, while Terra and Luna manage routine and batch processing. This new release transforms ChatGPT from a response generator into an execution system. It can now receive tasks, understand context, use tools, interact with environments, and deliver results. This means it can handle complex operations like financial analysis, updating spreadsheets, or generating presentations. The system is built to manage task decomposition, context, tool use, and permission control. Enhanced security features in GPT 5.6 require more stringent access control. This development aims to make AI systems more capable of performing complete, real-world tasks.
