The short version It was born usage-priced, standing beside the seat business rather than replacing it.
The verdict
Kiro did not exist in January 2025. AWS introduced it on 14 July 2025 as a free preview "with some limits"; the pricing page captured the same day showed "coming soon" tiers — Free with 50 agentic interactions a month, Pro $19 for 1,000, Pro+ $39 for 3,000. Before anything was billed the model was rebuilt: on 1 August 2025 the tiers became Pro $20, Pro+ $40 and Power $200 with separate vibe and spec allocations and overage at $0.04 per vibe and $0.20 per spec request. Paid plans went live on 15 August 2025 with overage as an opt-in, or "usage pauses at your monthly limit". A metering bug made August and September free. On 15 September 2025 the two request types were merged into one credit pool — 1,000 / 2,000 / 10,000 credits, overage $0.04 per credit — with billing from 1 October 2025. Pro Max ($100, 5,000 credits) followed on 11 June 2026, and between 22 June and 10 July 2026 individual tiers swapped pay-per-use overage for prepaid add-on packs ($0.04 per credit, $5 for 125 credits up to $100), leaving month-end overage to Enterprise admins. That split model stands at the 10 October 2026 capture.
