What it meant in practice
On a reference workload of 50M input and 5M output tokens a month, this change moved the bill from $6.50 to $10.50 a month, a difference of $4.00. The workload is a fixed reference used on every event page so the figures are comparable between them, not a measurement of anyone's usage.
Your recorded history should not change when prices do
A cost tracker carrying a single current-price table would reprice every mistral-small-4 session you ran before 2026-06-24 at the new rate, silently restating months you already paid for. See what this change does to a real session, and why dated windows are the fix.
