OpenAI rolls out GPT-5.6 in three variants under government oversight

OpenAI launches GPT-5.6 in Sol, Terra, and Luna with enhanced reasoning and a multi-agent ultra mode; access is limited to about 20 government-approved partners before broader rollout as regulators prepare a cyber Executive Order framework, signaling a transition period between private release and wide adoption while highlighting defense-oriented uses and ongoing safeguards; Anthropic is likewise negotiating safeguards, and OpenAI cautions that broad government access should not be the long-term default.
