GPT-5.6 Cyber: OpenAI's security model arrives in AWS GovCloud

OpenAI's GPT-5.6 Cyber is now available in AWS GovCloud (US-East) through Amazon Bedrock. It is offered under the name Daybreak Red and is meant for authorized cybersecurity work.

Access is limited to approved customers rather than open to anyone with an AWS account. The announcement frames the release around where the model runs: a US government cloud region, reached through Bedrock.

The material lists GPT-6.1 Terra and GPT-6 as earlier OpenAI models. It does not say how GPT-5.6 Cyber compares with them, so the main detail here is the specialized cybersecurity focus and the GovCloud availability.
