Where can you actually use it?

Choose your situation. Get the next step and its cost conditions. Not a chat model; no login or payment here.

I want a free option

Try a free alternative — not Fable.

Kiro Free offers 50 credits per month for supported models, including Sonnet 4.5 and open-weight options. It does not include Fable.
Open Kiro’s official pricing page, choose Download now, then check the available models after signing in. Start with one small coding task; credits are not a fixed number of messages.

I already have Claude Pro

Fable uses separately billed usage credits.

Check billing before selecting Fable 5 or 5.1. Pro’s included allowance does not cover them.
Prefer your included models if you do not want extra charges. Check the provider’s rules before enabling credits.

I already have Claude Max

Fable is included, within a separate usage limit.

Choose Fable 5 or 5.1 in Claude’s model picker.
Fable can use up to 50% of your weekly allowance. At the limit, switch models or deliberately enable billed credits.

I use Kiro Free or a personal paid plan

A personal Kiro upgrade does not unlock Fable.

The current model table reserves Fable 5.1 for a limited Enterprise preview. Check the table before buying a plan.
Use a supported model in your current tier. Opus 5.5 is listed on paid tiers at 2.0x credits, not Free.

My organization uses Kiro Enterprise

Ask your administrator about the preview.

Your organization must have preview access and enable Fable 5.1 through model governance.
Check US East processing requirements and the 6x credit multiplier before using company data.

I want API access without a chat subscription

No chat subscription does not mean free usage.

Use the official developer platform and check model pricing before adding funds.
Set a spending limit, protect your API key and start with a bounded test. Fable5.app does not issue keys or run your prompts.

Based on Claude’s plan rules and Kiro’s model/pricing pages. Provider terms and your account determine access; we cannot unlock a model. No prompts, account details or keys are collected by this guide.

The short answer

Kiro documents Fable 5.1 as a limited Enterprise preview—not a benefit of Kiro Free. Eligible administrators control access.

Is Fable available in Kiro?

Only as a limited preview for Kiro Enterprise customers, rolling out gradually. Kiro’s Free and individual paid tiers do not list it.

The free tier is a different offer

Kiro lists 50 free credits. That is not 50 fixed messages, and it is not free Fable. Check the model table as well as the pricing page.

Enterprise teams: who switches it on?

Administrators enable Fable 5.1 through model governance. The current entry specifies US East inference and a 6× credit multiplier.

What about Opus 5.5 and Sonnet 5.5?

Since September 28, 2026, Kiro lists Opus 5.5 with experimental support for Pro, Pro+, Pro Max and Power in the IDE, CLI, Crew and Web, at a 2.0x credit multiplier. It is not on Kiro Free. Restart Kiro to load the new model list. Sonnet 5.5, released the same day by Anthropic, was not in Kiro’s model table when we checked on September 29.

Questions readers ask

Is Fable free in Kiro?

No. Kiro’s free credits are a separate offer; Fable 5.1 is a limited Enterprise preview.

Official source (opens in a new tab)

Why don’t I see Fable in Kiro’s model picker?

It is rolling out gradually to Enterprise customers, in US East, and an administrator must enable it through model governance.

Official source (opens in a new tab)

Does Kiro offer Opus 5.5?

Yes, on paid tiers (Pro, Pro+, Pro Max, Power) since September 28, 2026, as experimental support at 2.0x credits. Not on Kiro Free.
