Both models bring GPT-6 improvements in professional work, coding, computer use, factuality, and communication at a lower price than .GPT-6 Astra
Both Sol and Luna communicate more directly than their GPT-5.6 counterparts, with less jargon and fewer low-value details. They also improve factual reliability and are less likely to make misleading claims about work completed during coding tasks.
