Codex's experimental context management replaces compression with notes + searchable history, slashing usage
EAccelerate_42 · x · 2026-09-05
Codex shipped an experimental context-management feature that replaces its repeated history-summarization (which loses details over long tasks) with notes + searchable history: Astra keeps notes across context windows and lets you search back through earlier messages and tool results in the same task, so past attempts, code-change rationale, and tool outputs are recoverable.
To enable, add this to /.codex/config.toml:
[features.contextmanagement]
experimentalmode = true
Then start a new task.
Caveats: requires a supported client and an eligible ChatGPT subscription login; API keys not supported yet. Some users report significantly reduced quota consumption.
