GPT-5.6 Luna

GPT-5.6 Luna ranks #25 out of 194 models on the public BenchAlign leaderboard, with a score of 65.6/100. Its evidence status is Supported, and this profile shows 30 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

GPT-5.6 Luna ranks #22 out of 158 eligible models for knowledge and understanding, with a public category score of 64.6/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

GPT-5.6 Luna ranks #9 out of 135 eligible models for coding and programming, with a public category score of 64.5/100. That places it in the current top ten for this category. Check the underlying rows before treating the aggregate as a workload guarantee.

GPT-5.6 Luna has source-displayable benchmark coverage for mathematics, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.

GPT-5.6 Luna ranks #18 out of 19 eligible models for reasoning and logic, with a public category score of 54.7/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

GPT-5.6 Luna ranks #28 out of 105 eligible models for agentic tool use and computer tasks, with a public category score of 55.3/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

GPT-5.6 Luna ranks #22 out of 50 eligible models for multimodal and grounded tasks, with a public category score of 67.1/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

GPT-5.6 Luna belongs to the GPT-5.6 family. Related tracked variants include GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Cyber. A sibling link indicates shared lineage or a documented configuration relationship; it does not mean the variants have identical pricing, context limits, benchmark evidence, or deployment behavior. Compare before switching.

No. GPT-5.6 Luna currently has 51 source-displayable rows across 483 tracked benchmark slots. 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.

GPT-5.6 Luna 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.
