OpenAI shipped GPT-5.6 as a tiered frontier family — Sol for deep reasoning, Terra for balanced work, and Luna for fast, cheap tasks.
The brief
The three-tier design lets logistics teams match model cost to task complexity: cheap routing or classification via Luna, complex tender analysis or contract review via Sol.
Takeaway
Operators should audit which logistics tasks need frontier reasoning versus fast pattern matching, then route prompts to the smallest adequate model.
Why it matters for logistics
Use Luna for high-volume, low-risk decisions (status coding, document triage) and reserve Sol for multimodal claims, contract analysis, and exception reasoning.
