UnverifiedAPI Keys are designed with no concept of expiration and remain valid long-term once generated; whereas tokens have an expiration time and require re-login to obtain after expiry.70% similarUnverifiedCache-aware routing preferentially sends requests to replicas that already have the same prefix in cache; when the cache is hit, prefill is almost zero, and first-token latency drops significantly.65% similarUnverifiedOnce a token has left the machine, deleting local files has no effect; logging out clears only the copy on the local machine, and the truly effective step is to revoke the API key at the source.65% similarUnverifiedStatic API keys typically have no built-in expiration mechanism and, once written into shell environment variables or configuration files, may persist in the system for months or even years64% similarUnverifiedModifying the system prompt to adjust effort invalidates the prompt cache; the official recommendation is to control effort via API parameters rather than prompt text in order to maintain cache validity.64% similar
