On Oct 30, AWS announced that Daybreak Red (GPT-5.6 Cyber, model ID openai.gpt-5.6-cyber), the OpenAI security model built for vulnerability research, is now on Amazon Bedrock in AWS GovCloud (US-East), after previously being offered only in US East (Ohio). Access still requires passing OpenAI Daybreak eligibility. GovCloud short-context pricing is $16.875 input and $101.25 output per 1M tokens, about 23% above Ohio at $13.75 and $82.50.
Key Takeaways
- ✓Regions: Daybreak Red can now be called In-Region in us-east-2 (Ohio) and us-gov-east-1 (GovCloud US-East); Geo and Global cross-Region inference are not supported (AWS announcement)
- ✓Eligibility: customers must first enroll in OpenAI Daybreak / Trusted Access for Cyber, then have their AWS account team enable access
- ✓Pricing: GovCloud short context (272K input tokens or fewer) is $16.875 input, $21.09375 for 30-minute cache writes, $1.6875 cache reads and $101.25 output per 1M tokens
- ✓Data: AWS says inference data is not used for training and Daybreak Red data does not need to be shared with OpenAI; it runs on an inference engine with zero-operator access enforced at the chip
- ✓API: served through the bedrock-mantle endpoint with OpenAI Responses and Chat Completions, and a 1,050,000-token context window

Background and pain point
Security teams working for government and defense are often limited by compliance to isolated clouds such as GovCloud, where many frontier models are not offered, and general models often refuse exploit reproduction or attack-chain analysis outright. OpenAI's Daybreak cyber program offers Daybreak Red (GPT-5.6 Cyber), a model with fewer refusals for vetted defenders, which has been on Bedrock in Ohio since August. AWS has now brought it to GovCloud (US-East).
How it works
The model ID is openai.gpt-5.6-cyber, served through the bedrock-mantle endpoint with the OpenAI Responses and Chat Completions APIs, a 1,050,000-token context window and In-Region inference only. AWS says it runs on the next-generation Bedrock inference engine with zero-operator access enforced at the chip, and that inference data is not used for training or shared with OpenAI. Access requires passing OpenAI Daybreak (Trusted Access for Cyber) eligibility.
Benchmarks and measured results
The announcement adds no new benchmark, only pricing. Per the AWS model card, short-context prices per 1M tokens in GovCloud are $16.875 input, $21.09375 cache write, $1.6875 cache read and $101.25 output, against $13.75 input and $82.50 output in Ohio. GovCloud is about 23% more expensive, and commercial prices already include the 10% AWS fee.
Developer takeaways
Security teams with government or compliance needs should confirm Daybreak eligibility with OpenAI or their AWS account team, then enable access in us-gov-east-1, where the endpoint looks like https://bedrock-mantle.us-gov-east-1.api.aws/openai/v1. Priority and Flex tiers are not supported and output is expensive, so prompt caching helps keep large codebase analysis affordable.
