GPT-5.6 Luna is the 5.6 fast/cheap tier. After the Jul 30 80% cut the official list is $0.20/$1.20 per million. That is a volume SKU. Putting Luna in a “best overall llm” article is how sites lie with averages. On CompareLLM, Luna shows up on cheapest-api and fastest lists, not on frontier-agent crowns.
The honest compare is Flash, not Sol
Gemini 3.7 Flash is on $0.75/$3.75 intro pricing through year-end with a huge context window. Luna vs 3.7 Flash is the 2026 cheap-hosted question. Sol vs Luna is an invoice, not a capability story.

Retries eat cheap models
If Luna retries twice, Flash or Haiku can win the real bill. Pair-page cost sketches are list price, not your traffic mix.
