12-hour prompt caching

OpenAI adds 12-hour prompt caching; Codex cache never expires

OpenAI's API now offers a 12-hour prompt cache aimed at always-on agents; writing to it costs 2.5x the input price versus 1.25x for the default 30-minute cache, and cache reads are 0.1x on GPT-5.6 and later. Tibo Sottiaux says the cache in Codex and Work never expires for logged-in users.

php2shell-checker

OpenAI publishes a checker for the PHP2Shell vulnerabilities

Alongside the PHP2Shell disclosure (two PHP engine RCEs, CVSS 9.2, fixed in 8.5.12, 8.4.27, 8.3.36 and 8.2.35), OpenAI published an open checker so server owners can see whether they are exposed. OpenAI's Daybreak program was among the groups that found the bugs.
