What it feels like
Official ecosystem
These are the verified first-party tools or official product surfaces currently listed for GPT-5.6 Luna. If there is no verified specialized tool beyond a general chat surface, this section stays minimal.
No separate specialized tool bundle is asserted for the model row.
GPT-5.6 Luna is the fastest and lowest-cost tier in the family. Its accepted HLE and SWE-Bench Pro evidence keep it competitive for high-volume workflows, while difficult tasks should still be tested against Terra or Sol.
