The earlier framing of $3\/$15 with an introductory $2\/$10 rate expiring on 2026-08-31 is gone. This changes what Claude tells you about cost, not what the API charges.\n\n**Details**\n\n- The migration guide's token advice changes with it: Sonnet 5's roughly 30% higher tokenizer count is now paired with a lower per-token rate, rather than described against unchanged pricing.\n\n**Evidence**\n\n`per-token pricing is lower than Sonnet 4.6: $2\/$10 vs $3\/$15 per MTok`\n\n- Area: Model Docs\n- Tier: You'll notice\n- Useful: 4\/5\n- Signal: 4\/5"}
