Spoiler: it does way more than Ghibli memes
Howdy wizards,
In this weekās edition:
ChatGPTās wild new image generator: what it is and how it might change design
Some specific ways you can use it in your work

Read on to see some viable business use cases for image gen with 4o
Hereās whatās brewing in AI.
DARIOāS PICKS
OpenAIās GPT-4o model now has native image generation and it almost makes DALL-E seem like it belongs in a digital museum. Itās available right inside ChatGPTājust make sure you've got GPT-4o selected in the model picker.
Hereās the deets:
GPT-4oās image generation is top of the line at rendering text and accurately following prompts
Itās really good at transforming images you upload by using them as visual inspiration (hello, all the Ghibli images all over your social media this week)
The accuracy of the image generation makes it not just impressiveābut useful for many everyday design and communication tasks
OpenAIās has released a series of short demos showcasing different aspects: character consistency, text rendering, detailed instruction following, transparent images and visual restyling.
ā Why it mattersā ā The devil is in the details when it comes to designāand OpenAIās latest brainchild is the first image generator that gets the details right. We might be at a point where a designersā workflow is truly changing, just like a developerās job has been transformed lately by vibe coding and tools like Cursor.
As you might expectāthis model is slow and GPU-intensive. Generations are way slower than DALL-E. The usage amount is also quite restricted: even on a paid plan, you will quickly hit the rate limits and have to wait 10ish minutes before you can resume using it. OpenAI also dialled back usage for free users to max 3 generations per day, saying their āGPUs are meltingā.
IN PARTNERSHIP WITH PREZI
Dario: Remember Prezi? The classic presentation tool just got an AI makeover, and it's transforming boring content into visual environments that might actually keep your audience awake. I've been testing their new AI features and found their AskAI text tools genuinely useful. These tools let you easily turn your presentation content into flowcharts, highlight key points, or transform paragraphs into bullets. Their initial AI-generated presentations definitely need some editing to shine, but still offer a fresh approach to visual storytelling that help your ideas stand out.
Here's how it works:
Generate a complete presentation framework from a simple prompt or PDF upload
Get a visual "world" related to your topic with Prezi's signature zooming interface
Transform your content with AskAI tools (no more switching to ChatGPT mid-design)
Great features for sharing your presentations with integrated audience analytics

Testing GPT-4oās image generation on design tasks
Iāve taken the 4o modelās new image generation for a quick spin on some common graphic design tasksāso itās easier to for you to judge what you can and cannot use it for in your own work.
Hereās some use cases where it really impressed me:

Who else fancies a cup of Wizardās Wakeup?
Task & score | Verdict |
---|---|
1. Icons/small illustrations ā 9/10 | ā Tested this on several small illustrations and UI icons. The prompt following works really well when itās just a single object. The model is nothing short of amazing at this use case. And the support for transparent backgrounds also makes the images much easier to include in a design workflow. |
2. YouTube thumbnails ā 7/10 | ā Gets the visual concept right, but not the best at getting the faces accurately. In this case, I asked it to mimic this Mr Beast thumbnail. |
3. Logos ā 7/10 | ā Does a fantastic job in making a draft of a concept. Though Iād still do several iterations on the result or polish it manually in an image editor, to make it shine. |
4. Product mockups ā 7/10 | ā Very good. It messes up a bit on the small text, but in general the result of creating a fictional product is nothing short of amazing. |
5. Explainer graphics ā 8/10 | ā The concept, the typography, the arrowsāeverything is in place. |
6. Product shot with model (model photo + product image) ā 6/10 | š¤ This feels at the edge of itās abilityāit mostly follows the prompt and gives an accurate rendering of the product, but as in the YT thumbnail the faces donāt fully resemble the original character. |
As you can see, thereās a lot of stuff that works really well.
Hereās the tasks Iāve tried where the result was not good:
One-shot infographics ā 4/10: š š»āāļø also includes other text heavy stuff. Itās pretty clear that when you overload it with content it starts messing upātext gets unreadable, images look less polished, etc. You could probably still generate pieces of your concept individually, then patch together in something like Figma/Canva.
Data visualisations ā 2/10: š š»āāļø this one is still totally off limits. I think data viz will stay firmly in the domain of traditional tools (that actually maps values to pixels in an exact way) for the foreseeable future. You mightāve already noticed the GPT-4o model has the mathematical precision of a toddler with crayonsāso it easily messes up the value mapping needed for charts.
A big upgrade overall is that you can now ask for transparent imagesāthis means the output is way more versatile and can easily be copied into tools like PS/Figma/Canva and used in your designs.
Other fascinating things people are using the new image generation for:
Creating product ads in different styles
2D character animation sprite sheets for games
Turning pictures from r/AccidentalRenaissance into actual renaissance paintings
Frame by frame animations ā asking for multiple images and for the ChatGPT to use Python to stitch them into an animation
Before you start wallpapering your company's channels with AI cartoons, remember: everyone and their tech-savvy grandma has access to this now. The internet is already being absolutely flooded with these images.
Thatās also why I think graphic designersā jobs are still safeāwhat makes creative work stand out is not just technique, but taste and vision, something AI doesnāt have (for now..).
