WHAT SHIPPEDGPT-5.6 family launches in general availability with Sol, Terra, and Luna. Sol scores 53.6 on Agents' Last Exam, 80 on the Artificial Analysis Coding Agent Index, 92.2% on BrowseComp, and 62.6% on OSWorld 2.0. Terra and Luna outperform Fable 5 at around one-sixteenth the cost.
THE CATCHThe efficiency numbers are the real story: Sol beats Fable 5 by 11.4 points at medium reasoning at roughly one-quarter the estimated cost, and Terra and Luna outperform Fable 5 at around one-sixteenth the cost. The ultra setting coordinates four agents in parallel by default.
IF YOU RUNa team paying per token for frontier models, the cost-per-task drop is the number to watch
