gpt-6 astra shipped with experimental codex features worth checking today, straight from openai's own release notes. the big one: a new way to preserve context across long tasks. instead of compacting a long debugging session into a lossy summary, codex now keeps searchable notes across context windows, so it can find a requirement or test result from earlier in the session even if the note didn't capture it directly. off by default, becoming the default "in the coming weeks" per openai. two more worth checking in your installed version. budgets, tracking a configured token budget during a task. sleep prevention, keeping your machine awake while codex works. paste this into codex: "inspect my installed codex version and experimental feature flags. check whether astra's new context management is fully enabled. explain which other features would help my workflow, verify the exact configuration, and show me a proposed diff before changing anything." worth knowing before you flip the switch: early reports on the context feature are genuinely mixed, and several negative reports about compaction issues don't even show the experimental flag turned on. treat this as worth testing, not a guaranteed fix yet. https://x.com/Av1dlive/status/2096234068828639474/video/1(CyrilXBT)
