What changed
Pro, Pro+, Pro Max and Power subscribers can buy add-on credits once their monthly allocation runs out, replacing overage billing. Credits cost $0.04 each in packs from $5 (125 credits) to $100; you can hold up to five packs, the earliest-expiring is used first, and unused credits last 12 months. Monthly plan credits are always spent first.
Who it affects
Individual Kiro subscribers who go past their monthly credits.
What to do
Buy packs sized to what you actually use, since they expire after 12 months.
