Unconditional, with no flag involved.\n\n**Details**\n\n- The new tier also sets cache writes at 2.5 (5-minute) and 4 (1-hour) and cache reads at 0.2 per million tokens.\n- This is a static data table shipped in the build, not a figure fetched from the API, so it applies immediately on upgrade.\n\n**Evidence**\n\n`pricing: \"tier_2_10\"`\n\n- Area: Cost Reporting\n- Names: `\/cost`\n- Tier: You'll notice\n- Useful: 5\/5\n- Signal: 4\/5"}
