GPT-5.6 Terra

GPT-5.6 Terra ranks #12 out of 216 models on the public BenchAlign leaderboard, with a score of 72.29/100. Its evidence status is Estimated, and this profile shows 23 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

GPT-5.6 Terra ranks #10 out of 55 eligible models for knowledge and understanding, with a public category score of 81.9/100. 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 Terra ranks #11 out of 133 eligible models for coding and programming, with a public category score of 65.1/100. 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 Terra 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 Terra has source-displayable benchmark coverage for reasoning and logic, 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 Terra ranks #10 out of 133 eligible models for agentic tool use and computer tasks, with a public category score of 63.3/100. 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 Terra ranks #10 out of 35 eligible models for multimodal and grounded tasks, with a public category score of 75.3/100. 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 Terra belongs to the GPT-5.6 family. Related tracked variants include GPT-5.6 Sol, GPT-5.6 Luna. 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 Terra currently has 46 source-displayable rows across 381 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 Terra 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.
