Pricing Details

OpenAISecurity-specialised tier of the GPT-5.6 family, announced 2026-08-10 alongside OpenAI's Daybreak program. Gated: requires enrollment in Trusted Access for Cyber, and on AWS a second access request through your account team. Priced at exactly 2.5x GPT-5.6 Sol on every line: $12.50 input, $1.25 cached input, $75.00 output, and a 30-minute cache write at $15.625 (1.25x input, the same ratio Sol and the rest of the family use). STANDARD TIER ONLY: OpenAI publishes no Batch, Flex or Fast rows for this model, which makes it the only GPT-5.6 tier with no cheaper service tier available. CONTEXT WINDOW IS CONTESTED between two primary sources: OpenAI's model page states 400,000 tokens with 128,000 max output (the figure stored here, since this entry's sourceUrl is OpenAI's own page), while the AWS Bedrock model card states 272K and files its single pricing table under a heading reading Short Context Window (272K). 272,000 is the long-context billing threshold on the rest of the GPT-5.6 family rather than a capacity limit, so AWS appears to have printed a billing boundary in a capability field; AWS publishes no long-context rate for Cyber at all. On Amazon Bedrock this model is In-Region only in us-east-2, served on the bedrock-mantle endpoint under model ID openai.gpt-5.6-cyber, launched 2026-08-12, at $13.75 / $1.375 / $17.1875 / $82.50, an exact 1.1000x on all four lines with Geo and Global cross-region inference both marked unsupported. No Bedrock batch or provisioned throughput exists for any GPT-5.6 model. Daybreak Blue is a separate Bedrock card (openai.gpt-daybreak-blue-5.6-sol) carrying GPT-5.6 Sol with relaxed cyber guardrails at Sol's In-Region rate and no Global row. Reported capability gap, secondhand via press rather than OpenAI's own page (which returned 403 on 2026-08-18): 95% completion on a sensitive-request set against 1.5% for general-access Sol. Rates confirmed on OpenAI's own pricing page (verified 2026-08-18).
