Frequently asked questions

How does GPT-5.6 Sol perform overall in AI benchmarks?

GPT-5.6 Sol ranks #4 out of 216 models on the public BenchAlign leaderboard, with a score of 81.48/100. Its evidence status is Supported, and this profile shows 25 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

Is GPT-5.6 Sol good for knowledge and understanding?

GPT-5.6 Sol ranks #6 out of 55 eligible models for knowledge and understanding, with a public category score of 83.3/100. That places it in the current top ten for this category. Check the underlying rows before treating the aggregate as a workload guarantee.

Is GPT-5.6 Sol good for coding and programming?

GPT-5.6 Sol ranks #3 out of 133 eligible models for coding and programming, with a public category score of 78/100. That places it in the current top ten for this category. Check the underlying rows before treating the aggregate as a workload guarantee.

Is GPT-5.6 Sol good for mathematics?

GPT-5.6 Sol 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.

Is GPT-5.6 Sol good for reasoning and logic?

GPT-5.6 Sol 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.

Is GPT-5.6 Sol good for agentic tool use and computer tasks?

GPT-5.6 Sol ranks #5 out of 133 eligible models for agentic tool use and computer tasks, with a public category score of 68/100. That places it in the current top ten for this category. Check the underlying rows before treating the aggregate as a workload guarantee.

Is GPT-5.6 Sol good for multimodal and grounded tasks?

GPT-5.6 Sol ranks #5 out of 35 eligible models for multimodal and grounded tasks, with a public category score of 84.7/100. That places it in the current top ten for this category. Check the underlying rows before treating the aggregate as a workload guarantee.

Which sibling models are related to GPT-5.6 Sol?

GPT-5.6 Sol belongs to the GPT-5.6 family. Related tracked variants include GPT-5.6 Terra, 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.

Does GPT-5.6 Sol have full benchmark coverage on BenchLM?

No. GPT-5.6 Sol currently has 49 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.

What is the context window size of GPT-5.6 Sol?

GPT-5.6 Sol 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.

Last updated August 10, 2026. Runtime fields remain blank until a sourced snapshot exists.
