GPT-5.6 Cyber
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

Available through OpenAI's "Daybreak Red" program, the more restricted of two tiers of their cybersecurity-specialized services which launched alongside GPT-5.6 Cyber.
How it is classified
Labels the source dataset applies when tracking notable models, and how confident it is in the entry.
- Why it is tracked
- Discretionary
- Record confidence
- Confident
Based on 5.6 Sol and thus assumed to be near-frontier general capability at time of release with specialized cyber capabilities.

What the numbers mean
Background
GPT-5.6 Cyber was published by OpenAI, in the country recorded as United States of America, during August 2026. The publishing organisation is categorised as industry.
It works in the domain of Cybersecurity, Language, and is recorded as performing the task of coding, Question answering, Software vulnerability discovery and exploitation.
Its starting point was an existing base model, GPT-5.6 Sol. That is why it shares the base model's general shape and size.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
What went into building it
It is tracked in the underlying dataset for one reason in particular: discretionary.
Answers
GPT-5.6 Cyber — common questions
GPT-5.6 Cyber— when was it released?
It was published in August 2026.
GPT-5.6 Cyber— what is it used for?
It works in the domain of Cybersecurity, Language, and is recorded as handling the task of coding, Question answering, Software vulnerability discovery and exploitation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
GPT-5.6 Cyber— what GPU do I need to run it?
None. This is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
GPT-5.6 Cyber— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
GPT-5.6 Cyber— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
GPT-5.6 Cyber— who created it?
It was published by OpenAI, based in United States of America, an organisation categorised as industry.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
