  "account": "A Reddit user has discovered that the Claude Code system's prompt cache duration can change unexpectedly, potentially leading to increased usage charges. For subscription users within their allotted usage, Claude Code retains the main conversation's prompt cache for an hour. However, once the user exceeds their plan limit and starts utilizing additional usage credits, the cache time-to-live is reduced to just five minutes. This means that the gap before Claude Code has to process the conversation again is 12 times shorter, even though the user is still in the same session.\n\nUsers who access Claude Code through an API key or cloud provider automatically receive the five-minute cache by default. In contrast, the longer cache duration of one hour applies only to the main conversation. Subagents, workflows, compacting, and session-title generation utilize a five-minute cache regardless of the subscription tier. Consequently, returning to a subagent after 10 minutes may require its context to be reprocessed, even on a Max subscription.\n\nHowever, users can modify this behavior by setting the promptCacheTtl to 1h or by using the CLAUDE_CODE_PROMPT_CACHE_TTL environment variable. These controls require Claude Code version 2.1.242 or newer, and API-key users can also utilize them. Additionally, switching models during an active session triggers a complete cache rebuild, which can be more noticeable when changing between Opus for planning and another model for execution. This is particularly relevant for Opusplan, as each transition into or out of plan mode counts as a model switch, potentially leading to multiple cache rebuilds.",
