OpenAI GPT-5.6: New Models for Enterprise & Cybersecurity

OpenAI has unveiled its newest family of AI models, including GPT-5.6, which comes in three variants: Sol, Terra, and Luna. The company states these models offer powerful capabilities for enterprise work, coding, and scientific research. What's interesting is that OpenAI claims GPT-5.6 is its strongest cybersecurity model yet, supporting defensive activities like threat modeling and code review. CEO Sam Altman also says the new models are significantly more efficient and cost-effective, with Sol being 54% more token efficient for AI coding tasks. OpenAI also released ChatGPT Work, a new tool designed to assist enterprise teams with daily clerical tasks on desktop, web, and mobile. The company explicitly compares its new models to those from competitor Anthropic, claiming GPT-5.6's Sol model outperforms Anthropic's Fable 5. The new models are now available across ChatGPT, Codex, and the OpenAI API, with varying pricing per million tokens. This development could change how businesses approach AI integration and cybersecurity.
