Coverage detailsHow much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

What it costs to get this score
Published API price against the public score. The x-axis uses a log scale; the dashed path marks models that are not beaten by a cheaper, higher-scoring option. Price uses average of published input and output rates.

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.
GPT-6.1 Sol ranks #23 of 210 on the public leaderboard with a score of 66.86/100. It does not yet have enough sourced coverage for a verified position.
GPT-6.1 Sol is a proprietary model with a 1.05M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
OpenAI documents GPT-6.1 Sol as an API model. It supports reasoning effort from low to max; tool calling is supported through the Responses API, while Chat Completions is supported without tool calling.
OpenAI's September 29, 2026 launch charts report exact DeepSWE v1.1, AutomationBench 1.0.6, and Terminal-Bench Science 0.1 results. We use Max effort for the canonical row, even when a lower effort scores higher. The system card adds separate raw and length-adjusted HealthBench results, ExploitGym, ExploitBench, and SEC-Bench Pro. OpenAI also reports 71.4% partial reward on the OSWorld 2.0 offline set, which we keep out of the binary-completion field. GDP.pdf, HealthBench Consensus, MentalHealthBench, and internal safety evaluations remain in the cited sources because their protocols have no confirmed matching field. These are provider-run results; the cyber scores are display-only.
GPT-6.1 Sol sits in the GPT-6 family with GPT-6 Astra, GPT-6 Sol, GPT-6 Luna. Its explicit predecessor is GPT-6 Sol. 11 of 486 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Its strongest eligible category is Coding at #8, while its lowest eligible position is Knowledge at #10. particularly well-suited for software development and code generation tasks.
Last updated September 29, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does GPT-6.1 Sol perform overall in AI benchmarks?
GPT-6.1 Sol ranks #23 out of 210 models on the public BenchAlign leaderboard, with a score of 66.86/100. Its evidence status is Estimated, and this profile shows 11 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.
Is GPT-6.1 Sol good for knowledge and understanding?
GPT-6.1 Sol ranks #10 out of 169 eligible models for knowledge and understanding, with a public category score of 71.3/100. 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-6.1 Sol good for coding and programming?
GPT-6.1 Sol ranks #8 out of 143 eligible models for coding and programming, with a public category score of 67/100. 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-6.1 Sol good for agentic tool use and computer tasks?
GPT-6.1 Sol has source-displayable benchmark coverage for agentic tool use and computer tasks, 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.
Which sibling models are related to GPT-6.1 Sol?
GPT-6.1 Sol belongs to the GPT-6 family. Related tracked variants include GPT-6 Astra, GPT-6 Sol, GPT-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-6.1 Sol have full benchmark coverage on BenchLM?
No. GPT-6.1 Sol currently has 21 source-displayable rows across 486 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-6.1 Sol?
GPT-6.1 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.
