OpenAI's next image generation model just showed up where it wasn't supposed to. GPT Image 2 appeared on LMArena, the anonymous AI benchmarking platform, under three code names: maskingtape-alpha, gaffertape-alpha, and packingtape-alpha. All three were pulled within hours of people figuring out what they were.
By then, the screenshots were everywhere. And they tell a clear story: OpenAI is coming for Nano Banana 2's crown.
Based on leaked tests, GPT Image 2 appears to beat Nano Banana 2 in photorealism, text rendering, and scene composition. Nano Banana 2 still leads on resolution (up to 4K), speed, and price.
What the leak actually showed
The leaked model showed five clear upgrades over GPT Image 1.5.
- Text rendering finally works. GPT Image 1.5 handled basic text but choked on dense copy. The leaked version produces clean, accurate text without the blurry edges or yellow tint from earlier models.

- Photorealism that fools people. Testers generated portraits that observers couldn't identify as AI. Beach selfies with natural lighting, correct hand anatomy, realistic reflections.
- World knowledge baked in. IKEA storefronts with accurate signage, YouTube interfaces with correct layouts, Windows UI mockups that look like actual screenshots. Previous models approximated these. GPT Image 2 nails them.

- Complex scene logic. Multiple people, objects interacting, spatial relationships that make sense. Most image generators still fall apart here.
- 16:9 aspect ratio support. GPT Image 1.5 maxed out at 3:2, so widescreen output for banners and slides wasn't really possible before.
Is Nano Banana 2 better than GPT Image for image generation?
Yes, but not yet.
Nano Banana 2 still has real advantages right now. It generates images up to 4K resolution. It's faster at standard resolutions: 2-5 seconds versus GPT Image 1.5's 5-15 seconds. And it's cheaper via API at roughly $0.045-$0.15 per image, with better resolution-per-dollar than GPT Image 1.5.
Community testers who tried GPT Image 2 on the Arena generally agreed it outperformed Nano Banana Pro by a wide margin. The photorealism gap that kept OpenAI behind Google? Based on what leaked, it's shrinking fast.
We think the leaked model looked polished enough for a public release within weeks, not months. OpenAI pulled those Arena entries quickly, which usually means they're close to launch and didn't want early comparisons circulating before they control the story.
| Feature | GPT Image 2 (leaked) | Nano Banana 2 |
|---|---|---|
| Photorealism | Ahead (based on leaks) | Strong, slightly behind |
| Text rendering | Major improvement | Good (87-96% accuracy) |
| Max resolution | Unknown (likely 2K) | Up to 4K |
| Generation speed | ~5-15s (estimated) | 2-5 seconds |
| API price per image | Unknown | ~$0.045-$0.15 |
| 16:9 aspect ratio | Confirmed | Supported |
| Availability | Not yet released | Available now |
What this means for Malaysian businesses
If you're already using AI image tools for marketing or product content, the GPT Image 2 leak is good news no matter which platform you use.
More competition means lower prices. If GPT Image 2 matches Nano Banana 2 on quality, both Google and OpenAI will fight on price. Malaysian SMEs using AI-generated visuals will get more for their money either way.
Better text rendering matters for Malaysian content specifically. If you've tried generating images with Bahasa Malaysia or mixed BM/English text, you know how badly most models handle it. Less time fixing AI output in Canva is a real win.
For developers building product catalog automation, marketing asset pipelines, or custom software with visual generation, two strong image APIs means better fallback strategies and negotiating power.
Don't rush to switch anything based on a leak though. Wait for the official release and test with your specific use cases. Leaked Arena models sometimes get dialled back before public launch.
Which AI image model should you pick right now?
GPT Image 2 vs Nano Banana 2 is playing out exactly like the LLM race did. Quality gaps are shrinking, prices are dropping, and the tools keep getting better.
At Gotchaa Lab, we've integrated AI image generation into several client projects. The advice we keep giving: don't lock your workflow to one provider. Build abstraction layers so you can swap models when something better shows up. Because something better keeps showing up.
