Story summary
- OpenAI announced three GPT-5.6 models—Sol, Terra and Luna—in the United States but limited access at the U.S. government’s request.
- Sol targets agentic work, Terra handles everyday tasks, and Luna is the smallest, cheapest model.
- OpenAI says Sol matches Anthropic’s Mythos on cybersecurity tasks while using only one-third of the output tokens.
- OpenAI called the limitation temporary, rejects permanent government-mandated access, and plans a broader release in weeks after tester feedback.
