Introducing Daybreak: Frontier AI for Cyber Defenders

推出Daybreak：网络安全前沿AI防御系统

OpenAI introduced Daybreak for cyber defenders, combining OpenAI models, Codex, and security partners; the post does not disclose pricing, launch timing, or concrete defense metrics.

Why it matters: OpenAI’s Daybreak announcement clears HKR-H/R as a security-focused product hook, but HKR-K fails: no defense metrics, access terms, or pricing. That keeps it in the 72–77 product-update band.
