A What it is for
It has no public model page, so context window and cutoff are unpublished.
At a three-to-one input-to-output ratio, GPT-5.5 Cyber costs $28.13 per million tokens blended. A workload of one million input and 330,000 output tokens per day would run about $1117.50 per month at list price, before caching or batch discounts.
