Codex /side chat suspected of causing full cache misses and burning plan quotas
YouJiacheng · x · 2026-09-11
Developer YouJiacheng noticed Codex's /side chat sometimes shows LOWER context usage (input tokens) than the main chat, suspecting content is being deleted; he's having Astra study Codex's source code. The thread flags that side chat may cause near-full cache misses — heavy side-chat users report burning through a 20x plan in a single day — and questions whether this is intentional design. Results pending.
