OpenAI confirmed that degraded cache hit rates across Codex caused requests to be reprocessed from scratch rather than referencing cached states. The backend regression led developers to drain their API quotas and session usage limits substantially faster during active coding sessions.
Why it matters. Cache failure abruptly multiplies API token overhead and halts developer workflows relying on persistent agentic IDE extensions.
