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-5.6 Cyber, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
GPT-5.6 Cyber is a proprietary model. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Available only through Daybreak Red trusted access under the gpt-daybreak-red alias. OpenAI identifies the API model as gpt-5.6-cyber.
Display-only trusted-access profile for GPT-5.6 Cyber, a separate model built on GPT-5.6 Sol. OpenAI reports a 95.0% Advanced Cyber Completion Rate for the Daybreak Red configuration. ACCR measures whether approved cyber tasks are completed rather than refused; it is an access-and-compliance measure, not a general capability score.
GPT-5.6 Cyber sits in the GPT-5.6 family with GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna. 1 of 486 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.
Last updated September 27, 2026. Runtime fields remain blank until a sourced snapshot exists.
Questions
How does GPT-5.6 Cyber perform overall in AI benchmarks?
GPT-5.6 Cyber has 1 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Which sibling models are related to GPT-5.6 Cyber?
GPT-5.6 Cyber belongs to the GPT-5.6 family. Related tracked variants include GPT-5.6 Sol, 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 Cyber have full benchmark coverage on BenchLM?
No. GPT-5.6 Cyber currently has 1 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-5.6 Cyber?
GPT-5.6 Cyber's provider has not published a context-window limit for this exact model. The profile leaves the value unavailable instead of borrowing a number from an earlier family member or a third-party route. Maximum output length is tracked separately when the provider documents it.
