OpenAI unveils GPT-5.6 amid US AI regulatory drama

OpenAI has released GPT-5.6, a new model suite including Sol, Terra, and Luna, just after agreeing to stagger its release at the request of the Trump administration. The models are optimized for coding, cybersecurity, biology, and long-horizon agentic tasks, with pricing significantly lower than competitors like Anthropic's Claude Fable 5. The launch occurs amid ongoing US AI regulatory developments.
