cost, model and stack, before you build

Model pricing is public. The right stack isn't.

Describe what you're building and get a monthly cost range, a model to start with, and a starter stack. It reads the same way a quote would, and it updates as you answer.

A two-minute walkthrough of how to use it

Narrated, with captions on screen. It shows how to start an estimate, read the results, and use the calculator, the models page and the keyboard, then the phone layout. Recorded October 2026, so small details may have changed since.

askmodel.dev estimates what an AI feature will cost before you build it, and suggests a model and a starter stack. Here's how to use it.

Start from an example workload. Pick one, and every answer fills in.

Or describe it in your own words. It suggests the workload type, the coding tool and your priority, and leaves anything it isn't sure about to you.

Then answer what applies: the platform, whether it makes money, how much speed matters, and your budget. The estimate updates as you go.

For a sharper estimate, pick your coding tool and open the usage details, like runs per day and tokens in and out.

The summary gives a monthly cost range, how confident the estimate is, the model to start with, and why.

The other tabs show where the cost comes from, every model side by side, suggested tools, and every assumption used.

Download the result as a PDF. It saves to your device, and it isn't emailed anywhere.

For a quick check, the calculator turns runs per day and token counts into a monthly cost for each model.

The models page lists every model by provider, with its price per million tokens, in and out. A note appears wherever a price varies.

Switch between light and dark whenever you like. It remembers your choice.

Everything works from the keyboard. Tab moves forward, Shift+Tab moves back, and Enter or Space presses a button.

On a phone, the menu collapses to a button, and the estimator stacks into one column.

That's everything. It's free to use. Please confirm any price with the provider before you build.

Five workloads, priced out.

§ 02 · how

Three steps, no signup.

  1. 01

    Say what you're building

    Pick a starting point or describe it in your own words. Nothing to install and no code to write.

  2. 02

    Answer what applies

    Volume, how long the answers run, how much it matters if it's slow. The rest has defaults.

  3. 03

    Read the range

    A monthly cost range, the model we'd start with, and why. It updates as you change an answer.

§ 03 · a note from Cheryl

Why the dates are on everything.

Every model here is checked against the provider's own page before it goes in, and it carries the day it was last checked. The most recent check was 2026-10-19, across 18 models.

When a price depends on volume, time of day or where it's hosted, the page says so next to the price. The estimator gives a range and tells you how sure it is. It's a planning tool, so please confirm the price with the provider before you commit.

§ 04 · price

The estimator is free. No signup, no email gate.

If you want a note when something new ships, leave an address. That's the only thing it's used for.
