A Beginner's Guide to AI Image Generators: Models, Styles, and Licensing
Every AI image model has a different visual signature and a different answer to 'can I actually use this commercially.' Both matter more than most people realize before they start.
Most people pick their first AI image generator based on whatever example images they saw on social media, then get frustrated when their own results don't look like that at all. Two things explain almost all of that gap: models have genuinely different visual signatures, and most people never check the actual licensing terms before using an output commercially.
Models have a visual 'accent,' not just a quality level
Midjourney has long leaned toward a stylized, painterly, immediately recognizable look - which is exactly why it's popular for concept art and mood pieces, and exactly why it's a poor fit if you need something that looks photographically neutral. FLUX and similar newer open-weight models tend toward more photorealistic, less stylized output, which makes them a better starting point for product photography or anything that needs to look unstaged. Ideogram has specifically distinguished itself on rendering legible text inside an image - a genuinely hard problem for image models generally, and worth knowing about specifically if your use case involves any text in the image itself (a poster, a sign, a logo mockup).
The licensing question nobody checks until it's a problem
Whether you can use an AI-generated image commercially - on a product, in an ad, in something you sell - depends entirely on the specific tool's terms of service, and those terms vary more than people expect. Some tools grant full commercial rights on any paid plan; others restrict commercial use to higher tiers, or exclude certain use cases (like training another model on the output) entirely. This is genuinely worth reading before you build a business asset around a specific tool's output, not after.
A simple way to start
- Know your use case before you pick a model - stylized/artistic versus photorealistic is the single biggest fork in the road.
- If text needs to appear legibly in the image, check that specifically - most models still struggle with it even in 2026.
- Read the commercial-use terms for your specific plan before you build anything you intend to sell or publish commercially, not after.
- Expect to need more than one tool if your work spans both stylized and photorealistic needs - very few models are genuinely excellent at both.
