Unlocking Precision: How AI Can Perfectly Generate Product Images
If we want to create images of a very specific item, such as a particular pair of sneakers, the standard general models are not suitable.
Imagine you’re designing a marketing campaign for a brand-new, limited-edition pair of sneakers. You want the images to be as specific as possible—every detail, from the exact shade of blue to the precise placement of the logo, needs to shine. Yet, when you turn to standard AI models for help, you might hit a snag.
The Generic AI Dilemma
Most AI models are trained on massive datasets filled with diverse images. They know what sneakers are and can generate images of them, but they often miss the mark when it comes to very specific products. Picture asking the AI to create an image of a particular pair of sneakers with a distinct blue shade, a white logo, grey laces, and a white sole. The AI might deliver a decent result, but it’s likely to fall short of the exact look you need. Instead of a perfect match, you end up with a generic representation.
The Challenge of Prompt Engineering
You might think that crafting a detailed prompt could solve this issue. For instance, you might specify “a blue sneaker with a white logo, grey laces, and a white sole.” While this approach can nudge the AI closer to your vision, it’s not foolproof. The AI can only approximate based on patterns it has learned, and achieving the exact visual result remains elusive. The detailed prompts might get you close, but the final image often still diverges from your precise requirements.
Sneakers are different each time, even though they are generated with the same prompt.
The Randomness Factor
Here’s another twist: the way models like Stable Diffusion generate images involves starting from random noise and iterating toward the final result. This means that every generated image can vary significantly in style, color, and perspective. Even with finely-tuned prompts, the inherent randomness in the process can lead to images that differ from each other, and from what you had in mind.
Sneakers are all generic, due to the generalisation of the pre-trained model.
Moving Beyond the Generic
If your goal is to have highly specific and consistent product images, relying solely on generic AI models and prompt engineering might not cut it. You may need to explore more advanced or specialized AI solutions, or consider integrating manual refinement to ensure that every detail matches your exact specifications. The technology is powerful, but understanding its limitations and capabilities is key to leveraging it effectively.
In a world where precision is paramount, navigating the challenges of AI-generated imagery can make all the difference.
Tailoring AI to Sneakers: A Sneak Peek into Fine-Tuning Techniques
Ever wondered how AI can become an expert on a specific sneaker? To tackle this challenge, we need to dive into the world of model fine-tuning—a powerful technique that adapts pre-trained models to master new, niche knowledge. Here’s how we can make a general model savvy about a particular sneaker:
Fine-Tuning: The Shortcut to Expertise
Fine-tuning is like giving our AI a crash course on a specific sneaker. Instead of building a model from the ground up (which is time-consuming and resource-intensive), we adjust an existing, pre-trained model to focus on new, targeted information. This process is not only faster but also more efficient.
Navigating the Challenges
However, fine-tuning isn’t without its hurdles. One major issue is the risk of “over-learning.” This occurs when the model becomes so engrossed in the new data that it forgets everything else it previously knew. Imagine an AI that was once a sneaker generalist but now only knows about one specific pair.
Capture the Perfect Sneaker Shots
To kick off the fine-tuning process, we need to gather high-quality images of our sneaker. For this step, we took 10 photographs of the sneaker from various angles, all set against a plain background.
Why so many angles? Each shot helps the model understand the sneaker from different perspectives, ensuring it learns every detail, from the curves of the sole to the nuances of the laces. The plain background is crucial—it keeps the focus solely on the sneaker, avoiding distractions and ensuring that the model can zero in on the product itself.
With these diverse, clean shots in hand, we’re all set to move on to the next stage of fine-tuning. Stay tuned to see how these images transform into a model that’s an expert on our specific sneaker!

Bringing Sneakers to Life: Generating Custom Images with AI
Once our model has been trained, it’s ready to work its magic. Imagine this: you can now generate fresh, unique sneaker images just by describing them with text prompts.
The results are nothing short of spectacular. Picture sneakers exploring various exotic locations, or strutting in a range of colors and styles you hadn’t even considered. The model can create stunningly realistic images that perfectly match your vision, bringing your wildest sneaker dreams to life.
See the following examples to witness the incredible versatility and creativity our trained model can offer!
