Damn it, GPT 5.6 is here! Ordinary people are temporarily unable to use it! The four versions are SOL Ultra, SOL, Terra, and Luna, named after them OpenAI has officially released its new generation of large-scale model GPT-5.6. This model includes at least four derivative versions: Sol Ultra, Sol, Terra, and Luna. In the field of underlying infrastructure and multimodal security confrontation, GPT-5.6 achieved its best performance in the Terminal Punch 2.1 benchmark test, which reflects terminal control capabilities. Its core versions Sol Ultra and Sol surpassed competitors Mythos and Fable 5 under Anthropic in benchmark scores, and are officially defined as the strongest cybersecurity model in the current market. In terms of specific cost models and token efficiency dimensions, GPT-5.6 exhibits extremely high density of inference efficiency. Evaluation data shows that GPT-5.6 Sol only requires less than 100K tokens of contextual bandwidth to surpass the intelligence level of domestic models such as Zhipu AI (such as GLM 5.2) that rely on stacking 2 to 3 times the number of tokens for complex task processing. It also breaks the intelligence limit of Anthropic Opus 4.7, which requires 200K tokens. In terms of pricing strategy, OpenAI has adopted a radical "price butcher" approach, with the distribution price of its basic version GPT-5.6 Luna approaching the rate range of domestic low-cost models, and the call friction cost of its flagship Sol being significantly lower than that of Anthropic's Opus and Fable series. OpenAI CEO Sam Altman confirmed after the press conference that the US Secretary of Commerce has personally implemented administrative intervention over the phone regarding the commercial distribution of the model, requiring that in the current initial preview phase, the trial be only open to a very limited number of customers who have been individually reviewed by the US government. The physical intervention of this national machine has substantially prolonged the friction cycle for cutting-edge models to fully enter the consumer market. In his subsequent public statement, Ultraman did not use aggressive PR language, but restrained himself by pointing out that the team had completed intensive security hardening in the past few weeks and had confidence in fully opening up this highly elastic and low-cost computing toolchain to global users in the coming weeks.
