#OpenAI发布GPT-5.6 When the "strongest model" meets the "narrowest door": The limited release of GPT-5.6



On June 27, Beijing time, OpenAI officially released the GPT-5.6 series of models.

Different from the past, this time there were no lights and cheers, replaced by an unprecedented threshold — at the request of the U.S. government, the model is only available for preview to a few "trusted partners."

GPT-5.6 is a model family with three tiers: the flagship version Sol (Sun), which set a new record of 91.9% on the Terminal-Bench 2.1 programming test; the balanced version Terra (Earth), whose performance is comparable to GPT-5.5 but at 2 times lower cost; and the lightweight version Luna (Moon), focusing on extreme cost-effectiveness
