OpenAI unveils GPT-5.6 amid US AI regulatory drama

OpenAI has unveiled GPT-5.6, including models Sol, Terra, and Luna, with a focus on coding, cybersecurity, and biology. The release comes shortly after the company agreed to stagger its model launch at the US government's request. GPT-5.6 Sol is priced at $5 input / $30 output per million tokens, positioning it competitively against other models like Anthropic's Claude Fable 5. The new models aim to excel in long-horizon agentic AI tasks, offering a range of options for different needs and budgets.
