OpenAI has officially expanded its latest model generation with the release of the GPT-5.6 family, introduced on July 9, 2026. This release breaks from the single-model launch tradition by offering three distinct tiers: Sol, Terra, and Luna. Nina Park and Thatcher Collins analyze the technical specifications, from the flagship Sol's premium capabilities to the high-efficiency Luna model. The episode focuses on the pricing documentation and system cards that reveal a unified 1.05 million token context window across the entire family, signaling a new standard for long-context handling in enterprise AI applications. We also examine the performance claims for Terra, which OpenAI positions as a GPT-5.5-class model at 50% of the previous cost.
