Lineage
The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track GPT-6 Luna (Decisions), but no weighted text-model benchmark result is published on the site yet. This page shows the metadata and separate protocol evidence we can verify now; a BenchLM score will appear only if compatible public evaluations land.
GPT-6 Luna (Decisions) is a proprietary model with a 1.05M context window. No explicit reasoning mode is documented in this profile.
Opened in public beta on October 6, 2026; OpenAI's guide now lists the Decisions API as generally available.
The profile has no source-displayable benchmark row yet.
Last updated November 11, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does GPT-6 Luna (Decisions) perform overall in AI benchmarks?
GPT-6 Luna (Decisions) does not have any source-displayable benchmark rows yet, so this profile does not assign a public score or rank. Documented specifications remain visible, while score-led charts and claims stay unavailable until a published evaluation can be attached to the exact model.
Does GPT-6 Luna (Decisions) have full benchmark coverage on BenchLM?
No. GPT-6 Luna (Decisions) currently has 1 source-displayable rows. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of GPT-6 Luna (Decisions)?
GPT-6 Luna (Decisions) has a documented context window of 1.05M. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
