Why the Model You Pick Matters
AdFlex gives you a choice of AI models for both image and video generation, and the model you choose has a bigger effect on the result than almost any other setting. Each model has its own personality: some chase photorealism, some excel at stylized art, and some are tuned to be fast and economical. Picking the right one for the job saves you credits and gets you to a usable result sooner. This article is an overview to help you choose, not a spec sheet for any single model. Model lineups change over time, so we group them by strength rather than fixate on names.
Image Models by Strength
Image models tend to fall into three groups. Match the group to what your ad needs:
- Photorealistic: These models aim for lifelike detail, believable lighting, and natural textures. Reach for this group when you need product shots, real-looking scenes, or anything that should pass as a photograph.
- Artistic and stylized: These models lean into illustration, painterly looks, bold graphic styles, and creative concepts. Use them for eye-catching social posts, brand visuals with personality, or anything that should clearly look designed rather than photographed.
- Fast and economical: These models prioritize speed and lower cost over maximum fidelity. They are ideal for rapid prototyping, testing prompt ideas, and generating lots of options quickly before you commit to a higher-fidelity model for the final piece.
Video Models by Strength
Video models split along similar lines, with their own priorities:
- Realism: Some video models focus on lifelike footage with natural motion and detail, best for polished, premium-feeling video ads.
- Motion control: Others give you more command over how the camera and subjects move, which matters when you have a specific shot or animation in mind rather than a general vibe.
- Cost: Video is the most credit-intensive feature on the platform, so some models are a more economical choice for drafts, tests, and shorter clips before you spend on a premium render.
When to Use Which
A simple way to decide:
- Need it to look like a real photo? Choose a photorealistic image model.
- Want a distinctive, designed look? Choose an artistic or stylized image model.
- Just exploring ideas or generating many options? Start with a fast, economical model, then switch to a higher-fidelity one for the final.
- Producing a premium video? Favor a realism-focused video model.
- Need a specific camera move or animation? Favor a motion-control video model.
- Drafting or testing video? Use a more economical video model first to conserve credits.
A good workflow is to prototype cheaply and finalize with quality: generate quick, low-cost drafts to lock in your prompt and composition, then regenerate the winner with a higher-fidelity model.
Models and Credits
Every generation consumes credits, and different models and settings cost different amounts. Video generally costs significantly more than images, and higher-fidelity or longer outputs cost more than quick drafts. AdFlex shows the credit cost before you confirm a generation, so you can always check the price first. To learn the mechanics of each generator, see AI Image Generation and AI Video Creation.
Common Questions
Which AI model is the best?
There is no single best model: it depends on the job. A photorealistic model wins for product photos, an artistic model wins for stylized brand visuals, and a fast model wins for quick experimentation. Match the model's strength to your goal.
How do I get a photorealistic result?
Choose a model from the photorealistic group and describe real-world details like lighting, setting, and texture in your prompt. See AI Image Generation for prompt-writing tips.
Do different models cost different amounts of credits?
Yes. Credit cost varies by model and by settings such as output length or quality, and video costs more than images. AdFlex always shows the credit cost before you confirm, so you can choose with the price in view.
Should I use an expensive model for every generation?
No. A practical approach is to draft with a fast, economical model to refine your prompt and composition, then switch to a higher-fidelity model only for the final result. This saves credits while still giving you a polished finish.
