Introduction
This guide compares GPT Image 2, Flux 2 Pro, and Nano Banana 2 across the criteria that matter in production: prompt adherence, anatomy, text rendering, speed, photorealism, character consistency, cost, and unique features. The honest answer is not that one model wins everything. Each model solves a different type of creative bottleneck.
For VideoAny users, the model choice matters because a video workflow often starts with one approved still. The better the still, the less correction you need once motion begins.
Model Overview
GPT Image 2 is best when the prompt has multiple constraints: exact object placement, legible text, repeatable characters, and design logic. Flux 2 Pro is strongest when anatomy, skin texture, and photorealism are the main requirements. Nano Banana 2 is built for speed, conversational editing, and high-volume iteration.
Round 1: Prompt Adherence
The source test asks for specific objects in specific positions. This is where GPT Image 2 usually feels more reliable. It follows layout constraints instead of producing a beautiful image that ignores half the instructions.
Use GPT Image 2 for ads, UI mockups, posters with text, product compositions, and any brief where the details are not optional.
Round 2: Human Anatomy
Flux 2 Pro has a strong case when the image depends on hands, feet, body pose, realistic skin, or close-up human detail. If a campaign needs believable people more than exact typography, Flux-style outputs can be the safer first test.
Round 3: Text Rendering
GPT Image 2 is the practical winner for signs, mugs, packaging, comic panels, menus, and interface labels. If the words inside the image matter, test text rendering separately before choosing a model.
Round 4: Speed
Nano Banana 2 shines when time and volume matter. If you need hundreds or thousands of quick alternatives, the fastest model can win even if the final polish is slightly lower.
Round 5: Photorealism
Photorealism is subjective. The source describes a blind comparison approach, which is the right method: show outputs without model names and ask which result feels real. For production, judge realism by your use case, not by model reputation.
Round 6: Character Consistency
GPT Image 2 is a strong choice for recurring faces, outfit continuity, mascot systems, and multi-image campaign sets. If the image will become a VideoAny animation or series, consistency at the still stage matters.
Cost and Workflow
Price per image is less useful than cost per usable image. A cheap model that requires ten retries may be more expensive than a pricier model that nails the brief in two attempts. Track usable output, edit time, and downstream video quality.
Practical Decision Guide
- Use GPT Image 2 for precision, text, layouts, and consistent characters.
- Use Flux 2 Pro for human realism and anatomy-heavy scenes.
- Use Nano Banana 2 for fast ideation and conversational edits.
- Compare models on one controlled prompt before scaling.
- Bring only the winning stills into VideoAny.
Conclusion
There is no universal winner. GPT Image 2 is the best default for structured creative work, Flux 2 Pro is excellent for believable people, and Nano Banana 2 is valuable for speed. Choose the model that reduces friction for the asset you actually need to publish.

FAQs
1) Which model should beginners use?
Start with the model that best matches the job: precision, realism, or speed.
2) Why compare image models for video?
Because the quality and consistency of the still image affects the final video.
3) Is GPT Image 2 always the best?
No. It is strong for controlled prompts, but Flux and Nano Banana can win on realism or speed.
