GPT Luna
OpenAI's focused, high-volume tier — the cheap, fast one.
GPT-6 Luna is OpenAI's cheap tier — for focused, high-volume tasks in OpenAI's own words — at $0.10 in / $0.50 out per MTok, a twentieth of Sol's input price. It shares the 1.05M-token context with the rest of the current line.
What it is good at
- High-volume steps at $0.10 in / $0.50 out per MTok
- The same 1.05M-token context as Sol and Astra
What it is less good at
- A focused tier, not a frontier one; no benchmarks published by OpenAI

Versions
One block per version, the current one first, each with its own anchor. The comparison table puts the costs and the family's benchmark columns side by side; the values are verbatim, and every one is sourced and dated in its version's section below and in the Sources list. A dash means the source publishes no figure, and nothing here is estimated.
No independent intelligence or speed index is republished here: Artificial Analysis measures both across labs, and its terms allow the link but not the copy — its figures live on its own pages.
