Output is billed at a multiple of input on most models. The Out/In column is that multiple — it matters more than the input price once output dominates your bill.
Across 150 billable models the rate spans $0.0075 (text-embedding-v1) to $37.5 (gpt-4.5-preview) per million input tokens — a 5000× spread. Picking the wrong tier is usually the single most expensive mistake here.
What OpenAI is good at
GPT-5.6 Luna is the volume workhorse — cheap enough for classification and routing, strong enough for most user-facing chat.
Before you compare: GPT-5.6 Sol is currently discounted by OpenAI itself (a promotional rate). Gateway Sol pricing is lower still, but by a smaller margin than the rest of the family.
