🗞️ GPT1.5 or Nano Banana? 💥🚀

If you’re new here, welcome! If you’ve been reading for a while, thank you for sticking around as we navigate this wild AI shaped shift happening across eCommerce. Each week I share what I’m experimenting with, what’s actually moving the needle, and the trends that deserve your attention before they hit your competitors’ playbooks.

A quick heads up. I’ve organized all previous editions into one searchable hub. If you want the full journey, it’s all here. Also, this is the last post for 2025! Hope you have enjoyed our journey together so far :)

GPT 1.5 or Nano Banana? Who is the New Visual King

Just when we thought Google was winning the AI image creation race, OpenAI threw a systemic curveball that shifted the battle from raw pixels to cognitive control. While Google’s Nano Banana Pro optimized for the "perfect shot" through high-resolution fidelity and reference-image anchoring, GPT Image 1.5 doubled down on the logic of the frame. It treats complex spatial requests like a physics engine rather than a guessing game. It didn't just provide a better brush; it provided a smarter art director that understands the semantic relationship between objects, effectively ending the era of "pretty but random" generations in favor of total architectural intent.

The Comparison Challenge

To see this shift in action, I ran a "Stress Test" prompt designed to break typical AI, testing complex lighting, specific text, and anatomical precision. You can run this yourself to see the divergence:

This is what I got back from Nano Banana:

And here is GPT 1.5…

The Breakdown: Surgical Precision vs. Studio Power

GPT Image 1.5 is the "Design Partner." In professional work, having to "start over" is a massive waste of time. GPT 1.5’s superpower is Instruction Persistence.

Unlike Nano Banana, where the canvas is largely static, GPT 1.5 allows you to edit specific sections of the screen while keeping the rest of the image pixel-locked. You can also queue up multiple images while you wait, refining them with surgical precision. It behaves like a high-end retoucher, making it the superior choice for AI-Ready Listings. It generates a structured asset where the text, lighting, and product placement stay exactly where you put them.

Furthermore, it respects the professional pace: you can queue up multiple images while you wait, refining them with surgical precision.

Nano Banana Pro is the "Studio Powerhouse." Powered by Gemini 3, it remains the king of material realism. While GPT 1.5 is the better architect, Nano Banana is the better "photographer." It pushes native 4K resolution and captures the "grit" of reality—micro-scratches on glass, natural skin pores, and complex lighting physics—without the slightly glossy "AI sheen." For high-end print or "hero" shots where the subsurface scattering of light on a product must be indistinguishable from a Leica photograph, Google holds the technical edge in raw atmospheric depth.

The Split into Elements Test

Let’s do another comparison. Ask GPT 1.5 and Nano Banana to split an image into elements with a transparent background. I took this image:

GPT 1.5 correctly split all the elements out. Amazing.

Unfortunately, Nano Banana Pro did not get the assignment.

Extracting Labels with Ease

If you have one clear shot of your product with clear labels, with GPT 1.5 Image, you can now extract the label and transfer the label on let’s say, a blurry product shot, like I did:

Sweet. See how clean and clear the new product image is?

Which One Should You Use?

Too many choices. That’s the reality of the AI era we live in.

• Choose GPT Image 1.5 if: You are building AI-Ready Listings at scale. If you need to generate 100 variations of a product in different room settings while maintaining 100% brand consistency, this is your engine. Its ability to "lock" the product and iterate on specific environment sectors is the new industry standard for e-commerce and real estate.

• Choose Nano Banana Pro if: You need gallery-grade realism. If your final output is a 60-inch print, a luxury brand hero image, or a shot that requires authentic location details, Google’s 4K pipeline is the gold standard.

The Verdict: A Professional Blend

At our PPC Ninja creative studio, the choice isn't binary; it’s a blend. We use both models as a tag team to cover the entire production spectrum. However, after producing hundreds of professional listing images for real-world clients, my team’s preference has become clear: they are liking GPT 1.5 a lot better. 

The reason? Predictability. When you’re managing high-volume listings, you can’t afford an AI that "hallucinates" a new layout every time you ask for a minor tweak. GPT 1.5’s ability to lock in the product while we iterate on the environment saves us hours of prompt-engineering. It feels less like a game of chance and more like a high-performance workstation.

Gemini is Now Available in Chrome!

Google has reimagined the browser as an "agentic" tool, moving beyond simple searches to a system that can autonomously perform multi-step tasks—like planning a trip or cross-referencing data across ten tabs—on your behalf. However, these features are not active by default; they require specific steps to unlock.

Step 1: Go to this page and download the all-new AI enabled Chrome browser.

Step 2: Install it and refresh your Chrome and start using it.

Step 3: Enter AI Mode in the Omnibox

The address bar (Omnibox) is now the primary entry point for agentic browsing. To move beyond a standard Google search and into the reasoning engine:

• The Shortcut: Type your query into the address bar. Look for the AI Mode sparkle icon that appears on the right side of the bar.

• Action: Click the icon or hit Tab + Enter. This shifts Chrome into "Thinking" mode, where it can navigate websites, read content, and fill out forms to complete your task.

Other cool things you can do with this new and improved Omnibar.

Start typing @ to access a bunch of shortcuts

Your new browser can now interactively answer any questions about a page. To activate it, simply click into the omnibar and select “Ask about the page”

Google Lens lets you select any section of any page and now you can chat with Gemini about it.

The Power Duo: GPT + Canva

The integration of GPT and Canva transforms a text-based AI into a visual strategist. By invoking the @Canva command directly within your chat, you bypass the friction of starting with a blank canvas. Instead of scouring templates manually, you describe your vision, and the assistant bridges the gap between your concept and professional design layouts.

Activate Canva by going to your GPT Settings → Personalization → Apps → Explore Apps and then connect to your Canva app.

Once you gave activated Canva and hooked it up in your account, you can simply activate it by saying @Canva at the GPT command line and then type your prompt.

When I prompted Canva to generate a product poster, it didn't just offer a single static image; it produced four distinct design directions. This variety is crucial for A/B testing or simply seeing how different visual hierarchies—like bold typography versus image-heavy layouts—impact your brand’s message.

The real utility lies in the seamless handoff. Each of the four generated options remains fully dynamic. Clicking a design opens it directly in Canva, where every element—from hex codes and font weights to grid spacing—is editable. You aren't stuck with an AI’s "best guess"; you have a high-fidelity starting point that you can refine to match your exact brand guidelines.

This workflow effectively eliminates "blank page syndrome" for non-designers. By combining GPT’s linguistic precision with Canva’s drag-and-drop flexibility, you can move from a rough product concept to a polished marketing asset in minutes. It’s no longer about "generating an image," but about collaborative iteration between AI speed and human curation.

Why This Combo Wins:

• Speed to Market: Reduces the design cycle from hours to seconds.

• Infinite Customization: Moves beyond static AI images into editable vector/layered formats.

• Contextual Relevance: GPT understands the intent of your poster, ensuring the initial templates align with your industry or tone.

In his latest update on RUFUS, Andrew Bell highlights a pivotal shift from passive AI to agentic action. He pointed out that that the real power of Rufus lies in its "Actions Stack", a sophisticated loop of Memory, Reasoning, and Action that moves beyond simple chat to execute complex shopping missions.

The most standout capability is the ability to step outside the Amazon eco-system and provide intelligence. Read the full article here.
