Gamma Plus

Deck generation where the layout engine is the genuine achievement and the model contribution is a modest amount of text and a few images.

STEEP

Genuine work exists on top of the API, but the multiple is high for what it buys. A motivated user has cheaper paths available.

§1 · Billing

What the price actually is

$12/month month-to-month. Gamma sells credits rather than seats at the lower tiers, and annual billing is advertised meaningfully lower. The pricing page renders client-side, so this figure cannot be machine-checked and is confirmed by hand.

§2 · Assumption

The usage this is priced against

20 decks a month generated from a prompt or an outline: text for a dozen slides each, plus a couple of generated images per deck.

Someone using it half as much sees double the multiple. The assumption is the argument — if you disagree with it, the number below is not about you. Change it in the calculator.

§3 · Arithmetic

The cost math, in full

Estimated monthly inference cost

100,000 input tokens$0.30

Mid-tier frontier text model at $3.00 / 1M input tokens · 20 decks; outlines in, slide copy out

80,000 output tokens$1.20

Mid-tier frontier text model at $15.00 / 1M output tokens

40 images$1.40

Hosted image generation at $0.04 per image · two generated images per deck

Rates come from a dated rate card of representative published API prices, not from the vendor. Nobody outside these companies knows what they actually pay; volume discounts and in-house serving both push real costs below these figures, which makes every multiple here a floor rather than a ceiling.

§4 · Reasoning

Why this verdict, not the number

The hard part of Gamma is not writing slide copy — it is making generated content land on a page that looks designed, at any length, without a human nudging boxes. That layout engine is real software and it is why the product is used as widely as it is. The model layer on top of it is thin and runs on licensed models, and the alternatives have closed considerably now that general assistants export presentations. Steep rather than wrapper because the thing you are paying for demonstrably is not the generation; it is just that the generation is what the marketing emphasises.

What the price buys besides tokens

  • UX craft
  • Distribution

Automatic layout that survives arbitrary content length is the product, and it is genuinely difficult. Sharing, analytics and the web-native format around it are the rest of what a paid seat buys.

§5 · Leaving

What you lose if you leave

Decks that look composed without opening a design tool, and a format that works as a link rather than a file. Reproducing that with a general assistant means accepting worse layout.

The honest cheaper path

A general assistant can draft the content and export to slides; the result is less polished. For anyone who wanted a document rather than a deck, that gap may not matter.

Cost per unit of our assumption

Scaling assumes your usage has the same shape as ours, just more or less of it. If your mix is different — far more output than input, say — the estimate drifts. It is an estimate either way.
