Pricing story

Price the application clearly on the website, then enforce usage inside the app itself.

The site should explain plans, limits, and why stronger models cost more. The ClastX application should actually track usage, switch models, and stop people before margins disappear.

Model burn rates

Let users switch models, but make the burn rate obvious so stronger models feel premium and the margins stay intact.

Test it in the app

mini

GPT-5.4 mini

1x credit burn

Best default for most coding sessions and the safest way to preserve margin.

Input: $0.75/1M
Output: $4.5/1M

5.4

GPT-5.4

3.3x credit burn

Stronger reasoning for harder implementation work, but it burns credits much faster.

Input: $2.5/1M
Output: $15/1M

5.5

GPT-5.5

6.7x credit burn

Premium model for the hardest requests. Keep this behind higher-value usage.

Input: $5/1M
Output: $30/1M

What your first dollars should buy

Spend on response quality, usage protection, and the ability to get paid back.

01

OpenAI credits so coding quality stays high

02

Hosting and support only after live usage starts

03

Usage metering and stop behavior before broad access

04

Billing infrastructure only when the paid story is sharp

Before checkout exists

The job right now is to make the paid future feel safe and easy to understand.

If the hard-stop rule is clear, the included credits are obvious, and model switching feels fair, adding Stripe later becomes an implementation task instead of a pricing panic.

Before payments go live

Make sure the product is ready to protect profit from day one.

The homepage promise is clearly about coding value, not generic AI.
The first paid plan can be explained in one sentence.
Credit burn is visible and heavy usage stops before margin disappears.
Users can switch models, but stronger models drain credits faster.

Pricing FAQ

Why not offer unlimited usage right away?

Because unlimited usage can destroy margin fast when developers lean on stronger models. ClastX should meter by usage cost and stop at the plan limit unless the user upgrades or buys a top-up.

How should model switching work?

All models can stay available, but they should burn credits at different rates. That gives developers choice while protecting the business from expensive heavy users.

What should happen at 100% usage?

ClastX should stop, show the remaining choices clearly, and push the user to upgrade or buy more credits. Silent overages are the easiest way to lose money.
