Kiro pricing: $0.02 a credit on every plan, $0.04 past it

How much does Kiro cost on each plan?

Kiro sells credits, and each of its plans is just a monthly bucket of them that you spend as you work. We read every row below from Kiro's pricing page and billing docs on 8 November 2026. US prices, before tax:

Kiro doesn't sell a yearly plan, so there's no discount for paying up front. Every price is monthly, and Kiro says it "processes paid subscriptions on the 1st day of each calendar month." Plan credits that you don't use by then are gone. If you work in AWS GovCloud (US), the price "is approximately 20% higher than commercial pricing," and there's no Free tier at all. On the free plan you get "open weight models and Claude Sonnet 4.5, with limits." The paid plans are where the newer models live, from Claude Opus 5.5 to OpenAI's GPT-5.6, as Kiro's model list shows.

How many credits does a Kiro request use?

A typical Kiro request uses about 0.79 credits on Auto, Kiro's default model router. Kiro gave that figure on 11 November 2025, when a new version of Auto cut usage: "A typical request that previously used 1 credit now uses 0.79 credits." Credits are metered to two decimals, so the smallest charge is 0.01. Other models cost a multiple of Auto. We applied Kiro's multipliers to that 0.79 and priced it at both rates, as of 8 November 2026:

So the 1,000 credits on Pro cover about 1,270 typical Auto requests (1,000 divided by 0.79), or about 290 if you run all of them on GPT-5.6 Sol. Read these as estimates, not as a quote. Kiro itself warns that "Models that share the same credit multiplier won't necessarily consume the same number of credits per task," since each one counts tokens and thinks in its own way. Long prompts cost more, too. A GPT-5.6 request that goes over 272K tokens is billed at double the listed rate, and Claude Haiku 5.5 jumps from 0.06x to 0.3x once it passes 100K. The heavy work is where it adds up. Kiro's pricing page says that complex prompts, "such as executing a spec task, typically cost more than 1 credit."

What does a month of Kiro cost?

A developer sending 40 requests a workday pays $20 a month on Auto or Sonnet 5.5, $35.60 on Opus 5.5 and $82.36 on GPT-5.6 Sol. Here's the math. Forty requests times 22 workdays is 880 requests. At 0.79 credits each, that's 695 credits on Auto. Multiply by each model's rate, then price anything over the plan at $0.04:

On GPT-5.6 Sol, Pro with add-ons would cost $102.36 (2,059 extra credits at $0.04 is $82.36, plus $20). Pro Max would cost a flat $100. Pro+ with add-ons wins at $82.36. Add-on packs start at $5 for 125 credits and top out at $100 a pack, with up to five packs at a time. They last 12 months, so a heavy month's leftovers carry into the next one. Plan credits don't.

When is a bigger Kiro plan cheaper than add-on credits?

A bigger Kiro plan is cheaper once you'd buy more than 500 add-on credits on Pro, 1,500 on Pro+ or 2,500 on Pro Max in a typical month. Each gap is the next plan's price difference divided by $0.04. Kiro launched Pro Max on 11 June 2026 for this reason. Its announcement says developers told it "there's a big gap between $40 and $200."

Uneven months change the answer. A plan's unused credits vanish on the 1st, while add-ons keep for a year. If you hit 1,800 credits one month and 600 the next, Pro plus add-ons costs $52 then $20, which is $72. Pro+ would cost $80 for the same two months.

Is Kiro free?

Yes. Kiro Free costs nothing and includes 50 credits a month, on open weight models, Auto, Claude Sonnet 4.5 and Sonnet 4.0. You can't buy add-ons on Free. Kiro's docs say that when you hit the limit, "you must wait until the next month for your credits to reset."

Since 1 November 2026, your first paid upgrade comes with a trial. Kiro's trial post says that on Pro "the rest of that month is on us," and on top of that you get 500 trial credits that last for 12 months. The trial took the place of a $20 discount. If you upgraded before 1 November, you keep it. Kiro's billing docs walk through a case: if you move to Pro at midnight UTC on the 15th of a 30-day month, you pay $0 and get 533 plan credits plus the 500 trial credits. If you start on Pro+ at the same moment, you pay $10.67.

Students get a year for free. If you're at one of the eligible universities, the Kiro Students tier gives you "1,000 credits per month" with no card and no overage charges, as Kiro's students post of September 2026 says. Kiro started with 11 universities in March, the September expansion added 121 more across 16 countries, and you verify once through SheerID.

What does Kiro cost for a team?

A Kiro team seat costs $20 a month for 500 shared credits, and you need at least two seats. This is credit pooling, and it became the default for new Enterprise customers on 4 November 2026, as Kiro's pooling post says. Each seat adds its 500 credits to one pool that the whole team draws from, and an admin can buy more at $0.04. Kiro's own FAQ is blunt about it: "The $20 per seat per month fee is an access fee for a credit pool."

That makes a seat half the credits of an individual Pro plan at the same $20. Ten developers on pooled seats pay $200 for 5,000 shared credits. Ten on individual Pro plans would pay the same $200 for 10,000 credits, though nobody could share. Pooling wins when usage is lopsided. If two heavy users burn 2,000 credits each and eight others use 100, the pool needs 4,800 credits: $200 in seats and nothing extra. Individual plans would put the heavy two on Pro+ ($40 each) and the rest on Pro, which is $240. Enterprise adds SSO, centralized billing and alerts at 80% and 100% of the pool.

How has Kiro pricing changed?

Kiro has switched from requests to credits and added two plans since August 2025. That month it billed you by the request, and past the limit it charged "$0.20/Spec request or $0.04/Vibe request," as its pricing explainer put it. On 15 September 2025 it moved everything into one credit pool, and the paid plans started to charge on 1 October. This is every change we could find on Kiro's blog:

What does Kiro cost next to the rest of your AI stack?

Kiro Pro plus ChatGPT Plus plus Claude Pro costs $60 a month, and much of that is the same thing bought three times. ChatGPT Plus is $20 on OpenAI's plan page. Claude Pro is $20, or $17 a month if you pay for the year, on Anthropic's pricing page. We read both on 8 November 2026. Kiro Pro already lets you run Claude and GPT models inside the editor. On top of that, Claude Pro comes with Claude Code and ChatGPT Plus comes with Codex. That's three coding agents for one person.

Whizi, which publishes this page, has no coding agent, no IDE and no API, so keep Kiro for the editor work. Whizi Pro costs $29.99 a month for 2,500 credits and puts Claude, GPT and Gemini chat in one app, plus 100 pictures a month, with credits per message varying by model. Video and music sit on the Powerhouse plan. It replaces the chat side of a ChatGPT Plus and Claude Pro pair, not the agents inside them. If you use Codex or Claude Code daily, keep that subscription. Cursor's own plans run from $8 to $200, covered in Cursor pricing, and Cognition's cloud agent is priced in Devin pricing.
