cyber selects the Cyber access program: standard, daybreak_blue, or daybreak_red. A program other than standard is supported only on BYOK requests that run on your own OpenAI key enrolled in that program; any other endpoint, including OpenRouter’s own OpenAI credentials, rejects it with a 400 error. Requests on OpenRouter’s OpenAI credentials always run standard. Omit the field unless your key is enrolled in a Daybreak program.
