Recently, we showcased an update on ChatGPT 5. Reactions to this update have been mixed; for some, it’s great, while for others, it’s disappointing. I want to specifically talk about text-to-image creation. On August 26, 2025, Google launched its Nano Banana, which has truly brought a sense of magic to text-to-image generation.
Â
Over the next five days, we conducted research to compare Nano Banana and ChatGPT to determine which tool excels in text-to-image creation. We didn’t just engage with the community; we also conducted hands-on tests. Our focus was primarily on the free versions of these tools. So, which one is better?
Â
Let’s outline our testing process:
1) We selected a female model for testing.
2) We used the same image on both tools with the same four prompts.
3) We measured timing, accuracy, and features available in the free versions.
Based on these criteria, we choose our winner.

Nano Banana vs. ChatGPT: A Real-World Test of AI Image Tools
Most AI comparisons online skim the surface. But when you’re actually creating content, you need to know: Which tool will deliver consistent, realistic results?
And in this case, the key thing I found? Nano Banana kept the model’s face accurate and consistent across all edits, while ChatGPT failed badly — changing facial features and breaking realism.
Here’s the breakdown.
Prompt 1 – Fashion Style
Make this female wear a modern boho chic outfit with layered jewelry, soft pastel colors, and stylish heels. Keep it elegant and Instagram-worthy.
Nano Banana delivered exactly what was asked for. The model’s face stayed true to the original photo, while the outfit, jewelry, and heels matched the boho chic style. The image looked like it belonged in an Instagram fashion feed — elegant, trendy, and natural.
ChatGPT, however, stumbled here. Not only did it miss key accessories, but it also altered the model’s face in this test. The result no longer looked like the same person — a critical flaw if consistency matters. The timing was also slower(free version), making the process drag.
Prompt 2 – Eating American Food
Make her sit at a cozy restaurant table, enjoying a classic American burger with fries and a soda. Capture the moment naturally.
Nano Banana gave me a realistic, candid dining scene. The burger, fries, and soda looked natural, and the setting felt cozy and authentic. Most importantly, the model’s face stayed exactly the same — you could tell it was her, simply in a new environment.
ChatGPT, on the other hand, delivered a stiff, stock-photo vibe. The model’s facial details were inconsistent, sometimes changing shape or expression unnaturally. Instead of enhancing realism, it broke it.
Prompt 3 – Restaurant Advertisement
Turn this photo into a restaurant ad with her eating in the scene. Add a warm, inviting background with soft lights, styled like a modern food commercial.
This was the make-or-break moment. Nano Banana excelled, producing an ad-worthy scene with warm lighting, inviting background, and the model enjoying her meal naturally. The face remained perfectly intact, which made the ad believable and professional.
ChatGPT fell apart here. The lighting was flat, and in some outputs, it even tried adding clumsy text or logos that looked amateurish. Worse, the model’s face often looked distorted, so the ad didn’t even look like it featured the same person.
Prompt 4 – Stylish Shade Portrait
Make her portrait look like a fashion magazine photo, with stylish sunglasses, dramatic shadows, and a premium luxury vibe.
Nano Banana turned out a high-fashion portrait. The sunglasses were stylish, the shadows dramatic, and the overall vibe premium. The model’s face remained unchanged, giving the portrait consistency and professionalism.
ChatGPT once again failed the facial test. Sunglasses looked generic, shadows lacked depth, and the biggest flaw — the model’s face was altered. Instead of one consistent subject, it looked like a different person altogether.
Final Thoughts According To The Test
Across all four prompts, Nano Banana didn’t just outperform ChatGPT in speed, realism, and free features — it also preserved the model’s face every single time. This detail matters. If you’re creating campaigns, ads, or brand visuals, you need your subject to remain the same person.
ChatGPT simply couldn’t deliver. Its outputs were slower, less accurate to the prompts, and, most damaging, it repeatedly changed the model’s facial features. The results felt artificial, filtered, and unreliable.
The verdict is clear: Nano Banana is the winner — faster, more accurate, more realistic, and consistent with faces.
What the Community Thinks about ChatGPT and Nano Banana?
We didn’t just rely on our own tests — the AI community has been buzzing about Nano Banana vs. ChatGPT too. On Reddit and other forums, users compared the same prompts and shared their results. The overall vibe? People noticed the same thing we did: Nano Banana consistently kept faces accurate, details sharp, and scenes realistic. ChatGPT, on the other hand, often struggled with facial consistency and missed key details in creative prompts.
In these discussions, users highlighted how Nano Banana could even take abstract prompts and produce imaginative, polished images that still looked like the original person. Many favored its output for ads, fashion, or social media content because the images were both fun and believable. ChatGPT’s outputs, while technically fine, were often described as generic, inconsistent, or slightly off — exactly what we saw in our tests.
So, when you combine what the community says with our hands-on experiments, the story is the same: Nano Banana is the winner for now, in August 2025. It’s faster, more accurate, and most importantly, it keeps your subject’s face intact. For anyone serious about text-to-image creation — whether for campaigns, social posts, or just fun projects — Nano Banana isn’t just a community favorite, it’s the tool that delivers reliable results every time.
