Atlas Photorealism Picks
This table mirrors the Image Bay photorealism node in Atlas. Scores are rounded Sonnet 4.6 public leaderboard scores, so they match the current public data contract for image-model recommendations.
| # | Model | Sonnet Score | Cost/Image | Tier |
|---|---|---|---|---|
| 1 | GPT Image 2 (High) | 4.16 | $0.212 | Premium |
| 2 | Seedream 4.5 | 4.04 | $0.040 | Standard |
| 3 | Nano Banana 2 | 4.02 | $0.067 | Premium |
What Photorealism Tests
Photorealistic prompts are unforgiving because viewers notice small physical mistakes. A model needs material texture, lighting, subject structure, and prompt adherence to work together. A good-looking image can still fail if the hands, reflections, or spatial logic do not hold up.
Useful signals
- Natural material texture instead of plastic smoothing
- Lighting that matches the scene geometry
- Clean edges around people, products, and props
- Prompt details that survive in the final image
Common breaks
- Hands, ears, jewelry, or small props deforming
- Reflections and shadows pointing in the wrong direction
- Background blur bleeding into the subject
- Texture that looks painterly when the prompt asks for a photo
See the Picks Side-by-Side
Below, each row shows the three Atlas picks side-by-side on the same prompt - generated and judged blind in three independent Sonnet 4.6 passes. Winners are ringed in accent; hover any image for the judge's rationale, or click to open the lightbox. Three additional fashion-photography prompts are slotted in for visual range; they sit outside the scored Sonnet sample and are clearly tagged.

Which Model Should You Use?
Best single photoreal render
GPT Image 2 (High)
Use it when the image needs to survive close inspection: product hero shots, editorial scenes, difficult lighting, or dense material detail.
Best standard-price photoreal option
Seedream 4.5
Use it when you want a strong photoreal finish at $0.040/image instead of premium-tier pricing.
Best close premium generalist
Nano Banana 2
Use it when you want a polished generalist close behind the top Sonnet-ranked models, especially for broader image batches.
Strengths and Limitations
GPT Image 2 (High)
Strengths
- +First Atlas pick for photorealism
- +Top current public Sonnet score
- +Best fit when visual fidelity matters more than price
Limitations
- −Premium cost makes large batches expensive
- −May be more than you need for quick drafts or social tests
Seedream 4.5
Strengths
- +Strong photoreal finish at standard-tier pricing
- +Second Atlas photorealism pick
- +Good default when you need many strong-looking variants
Limitations
- −Does not beat GPT Image 2 High on the public score
- −Still costs more than true budget models
Nano Banana 2
Strengths
- +Close third in the Atlas photorealism node
- +Polished generalist for broader image batches
- +Competitive with premium models near the top of the leaderboard
Limitations
- −More expensive than Seedream 4.5
- −Not the first pick when pure photoreal value is the priority
The Practical Takeaway
If you want the safest photoreal output, start with GPT Image 2 High. If you are making many options and need the best quality-per-dollar near the top, start with Seedream 4.5. If your workflow already favors the Nano Banana family, Nano Banana 2 remains close enough to test.
The difference between a good photoreal model and the right photoreal model usually appears in your own prompt style. Run the top three on the same prompt set before standardizing a production workflow.
