GPT-6 Astra ships compaction in Codex: notes persist and old context stays searchable

danielmac8 details GPT-6 Astra's new compaction mechanism in Codex:

- Searchable earlier windows: past messages and tool calls can be retrieved.
He argues this makes the model far less amnesiac and makes the context window feel massive.
