Should I use ChatGPT or Lume for product photos?
When ChatGPT is enough, and when a store needs a tool built for product photography
Updated
Quick answer
Use ChatGPT for one-off images, mock-ups and shoot ideas, especially if you already pay for it. Use Lume when the photos go on a store: it starts from your product photo and 4,000+ ready-made scenes, keeps a whole catalog in one look, generates in batch, and outputs fixed sizes for marketplaces, from about 11 to 15 cents an image. OpenAI itself says its image model can struggle with precise text and with keeping brand elements consistent, which is what product listings depend on.
Side by side
| ChatGPT Images | Lume | |
|---|---|---|
| How you start | Describe the scene in a prompt, optionally with your photo | Upload your product photo and pick one of 4,000+ designed scenes |
| Labels and logos | OpenAI says text placement and brand consistency can be a struggle | Built to keep your product as photographed; check small text before publishing |
| Same look across 50 products | Hard: each image is generated separately and scenes drift | Use one scene for every product |
| Batch | Not in the app; API and code only | Batch generation on every plan |
| Output size | Aspect ratio picker; pixel size not published | 1K, 2K or 4K in 10 fixed shapes, e.g. 2048 x 2048 square |
| Price | Included in Free (limited), Go, Plus ($20), Pro ($100+); image limits not published | Free to try; Pro $9 for 60 images, up to Studio $79 for 720 |
| Commercial use | You own the output | Commercial licence on every plan |
| Best for | One-off images, mock-ups, ideas | Store listings, catalogs, ads in many sizes |

When ChatGPT is the right choice
- You need one image, not fifty. A hero shot for a launch post, a mock-up for a pitch, a background for a single listing.
- You are exploring ideas. Asking for ten different moods for a new product is fast in a chat.
- You already pay for it. Plus at $20 a month includes image generation alongside everything else.
- The product has no fine text. Plain objects with no label or logo are the easiest case for any image AI.
When a store needs Lume
- Your listings must look like one brand. A shop where every product sits in the same light, surface and angle reads as professional. Lume does it by reusing a scene, not by re-describing it.
- Your label is the product. Skincare, candles, supplements and drinks sell on the label. Lume starts from your photo of it rather than redrawing it.
- You have more than a handful of products. Batch generation makes a scene for every product in one go.
- Every channel wants a different size. Square for Amazon and Etsy, 4:5 for Instagram, 9:16 for TikTok, 16:9 for ads, at known pixel sizes.
- You want a scene designed, not described. Each Lume template already sets the lighting, surface, props and composition.

Frequently asked questions
- Can ChatGPT make product photos?
- Yes. Upload a photo of your product and ask for a new background or scene, and ChatGPT Images will make one. For a single image, a mock-up or ideas for a shoot it works well, and it is included in every ChatGPT plan, from Free to Pro.
- Does ChatGPT keep my product exactly the same?
- Not reliably. OpenAI's own documentation says the image model can struggle with precise text placement and with keeping brand elements consistent across generations, and independent tests report labels, logos and small details changing between edits. Always compare the result with your real product before you publish it.
- Can ChatGPT make photos for a whole catalog at once?
- Not in the ChatGPT app: there is no batch or bulk image feature, so each image is its own conversation turn. Batch work needs the OpenAI API and some code. Lume has batch generation on every plan: pick one scene and generate it for every product.
- What sizes does ChatGPT make images in?
- ChatGPT lets you pick an aspect ratio but does not publish the pixel size it outputs. In the API, sizes must be multiples of 16 pixels with a longest edge of 3840, so exact sizes like 1000 x 1000 need resizing afterwards. Lume publishes every size: a square image is 1024, 2048 or 4096 pixels.
- Can I use ChatGPT product images commercially?
- Yes. OpenAI's terms say you own the output, with the caveat that output may not be unique. The same is true of Lume: every plan includes commercial licensing.
- Is Lume cheaper than ChatGPT?
- It depends on what you already pay for. If you have ChatGPT Plus ($20 a month) for other work, a few product images cost nothing extra. Lume Pro is $9 a month for 60 images at 1K, and Studio is $79 for 720, about 11 cents each, with output sizes and plans built for product listings.
