Will it make up market figures if I leave them out?

Yes, and they will look credible. Always supply your own numbers. The figures in the official prompt are explicitly fictional design inputs.

Is the bar chart plotted from data?

No. It draws the trend shape you described. If the specific values matter, state them year by year and then check the result.

The slide carries axis labels, footnotes and a legend simultaneously. Multiple sizes of small text in one image is the workload HD exists for.

Can I get an editable file?

No — this is a raster image. It is useful as a layout to rebuild from, or as a placeholder while the deck is taking shape.

Put the actual numbers in the prompt. A chart with invented figures is a picture of a chart.

A "Market Opportunity" slide with a TAM/SAM/SOM diagram, a growth bar chart and footnotes. What separates this from a generic "make me a startup slide" prompt is that every number, every label and every footnote is written out. The model is being asked to lay out data it has been given, not to invent data that looks plausible — and plausible invented data on a fundraising slide is a serious problem.

In full

The prompt, nothing cut

Create one pitch-deck slide titled **"Market Opportunity"** that feels like a real Series A fundraising slide from a YC-backed startup.

Use a clean white background, modern sans-serif typography like Inter, and a crisp, minimal layout. The slide should include:

* A TAM/SAM/SOM concentric-circle diagram in muted blues and grays
* Specific, believable market sizing numbers:

 * **TAM:** $42B
 * **SAM:** $8.7B
 * **SOM:** $340M
* A clean bar chart below showing market growth from **2021 to 2026**, with a subtle upward trend
* Small footnotes: **"AGI Research, 2024"** and **"Internal analysis"**
* A company logo placeholder in the bottom-right corner

The design should look like it belongs in a deck that actually raised money: highly readable text, clear data hierarchy, polished spacing, and professional startup-style visual language.

Avoid clip art, stock photography, gradients, shadows, decorative elements, or anything that feels generic or overdesigned.

The mode and all five settings are locked to this template, so there is nothing to line up by hand. Press Run this prompt above and the panel opens filled in — prompt, mode, quality, size and frame — and your first image needs no account. If your plan sits below what this ran at, the line under the panel says so.

What is safe to change

Most libraries publish this list and stop, which is why so many copied prompts come back worse than the original: the swappable nouns are the safe half. The three sections under it are the other half — the clauses that are doing the work, the ones that break it if you touch them, and why it is written in this order.

The numbers themselves
TAM $42B, SAM $8.7B, SOM $340M. Replace these with yours before you do anything else. The sample figures in the official example are explicitly labelled fictional design inputs.
The component list
Diagram, chart, footnotes, logo placeholder — written as bullets, which is what makes the layout come out with real hierarchy instead of one big graphic.
The exclusion paragraph
Clip art, stock photography, gradients, shadows, decorative elements. This is the line that makes it look like a real deck rather than a template, and it is the one people leave out.

Three ways to break it

Each one is a real failure with a reason attached. A rule without a reason is not usable.

01Leaving the numbers out and letting it invent them
It will invent them, and they will look completely credible. A slide with fabricated market sizing that reaches an investor is not an aesthetic problem. Supply the figures.
02Running it at Standard
The slide contains axis labels, footnotes and a legend — several sizes of small text at once. That is the exact workload HD exists for, which is why the official example specifies it.
03Treating the bar chart as accurate
The bars will show "a subtle upward trend" because that is what was asked for. They are not plotted from data. If the shape of the trend matters, state the value for each year, and check them.

Why it is written this way

Inside the Build a pitch-deck slide with your real numbers on it prompt

OpenAI's framing for productivity visuals is to write the prompt like an artifact spec rather than an illustration request: name the exact deliverable, define the canvas and hierarchy, provide the real text and data, describe the visual language. This slide is the clearest demonstration of that in the guide.

Look at the proportions. Roughly a fifth of the prompt is about how it should look; the rest is content and constraints. The component list is a bulleted spec — a diagram, three named figures, a chart with a stated year range, two named footnotes, a logo placeholder in a stated corner. That is not a description of an image. It is a build order.

The reason this matters more here than for most images is the data. A model asked for "a market sizing slide" produces a market sizing slide, complete with numbers, and those numbers will be well-formed, correctly ordered, and entirely fictional. They will also look exactly as authoritative as real ones. The official guide is careful to flag its own sample figures as fictional design inputs and to say they should be replaced with verified data before use — and that warning belongs on every copy of this prompt, including this one.

The closing exclusion paragraph is the second thing to steal. "Avoid clip art, stock photography, gradients, shadows, decorative elements, or anything that feels generic or overdesigned" is a description of everything that makes a slide look like it came from a template pack. Most slide imagery in the training data is template-pack material, so without this line that is the average you land on. Naming the whole category as unwanted moves you off it in one sentence.

A note on size, because this template is the reason it changed. The official example specifies `1536x864`, which is legal under this model's constraints — both edges divisible by sixteen, long edge under 3840, ratio inside 3:1, total pixels inside the permitted band — and for a while it was not one of the pairs this site offered, so 16:9 at 1K resolved to `1280x720` and the published example could not be reproduced exactly. It resolves to `1536x864` now. On a slide that is not a cosmetic difference: the labels on a TAM/SAM/SOM diagram and the footnote under a bar chart are small type, and small type is the first thing to go when the frame loses a fifth of its width.
