I recently tested Gemini 2.5 Flash Image (code name: nano banana) — the latest AI image generation & editing model that just topped the LMArena benchmark. Even better, you can try it for free inside iMini：https://imini.com/en/nano-banana
Key highlights:
·Blazing speed: up to 500 calls per minute
·Super cost-effective: text I/O 2.50, image generation 30.00
·Knowledge updated: up to June 2025
This nano banana review dives into five core testing dimensions:
Dimension 1: Character Consistency ★★★★☆
This is banana’s strongest suit.
·Case 1: Random strangers → couple in Paris
Two separate portraits fused into a romantic street photo. Great expressions and atmosphere, though the background looked a bit like stock photography.
In this nano banana review, I’d say this is its strongest suit.
Dimension 2: Image Editing ★★★★★
This section of the nano banana review proves why the model is a game-changer.
·Fixing the classic “six-finger” ad photo
Prompt: Keep everything the same but remove one extra finger.
Instantly corrected — no masks, no manual edits.
·Creative play: instant tattoos
Prompt:
Take the butterfly tattoo design from the woman’s upper arm in the reference image and place it on the collarbone and neck area of the short-haired woman.
The tattoo should blend naturally with the skin.
The result looked like a professional tattoo studio render — realistic and clean.
This dimension is the most practical and scored a full 5 stars.
Verdict: A full 5 stars, making this dimension the most practical highlight of the nano banana review.
Dimension 3: Style Transfer ★★★★☆
Another important section of this nano banana review: style versatility.
·3D → photorealistic → oil painting → anime, all handled smoothly.
·Oil painting had nice baroque lighting; anime style was clean and dreamy.
·Pixel art and toy styles, however, felt rough and under-detailed.
·Overall: solid but not jaw-dropping.
Dimension 4: Multi-Image Fusion ★★☆☆☆
Here’s where my nano banana review points out weaknesses.
·Simple outfit change: took 3 rolls to get a decent result.
·Complex edits (outfit + scene + action): stability dropped sharply — mismatched clothing and weird background text.
Conclusion: Multi-image fusion is Nano Banana’s weakest point in this review.
Dimension 5: Creative Generation ★★★★☆
The fun part of this nano banana review: creativity for social media and viral content.
·3D figure packaging: turn a portrait into a collectible figure, complete with box, base, and modeling screen.
·Classical bust variant: marble pedestal, golden nameplate, gallery spotlight — very aesthetic.
·Pixel toy variant: retro 8-bit packaging + game console screen, fun and nostalgic.
Final Verdict
·Pros: fast, affordable, strong consistency, flawless editing, highly creative use cases.
·Cons: weak stability in complex multi-factor tasks; certain styles underperform.
In short: Gemini 2.5 Flash Image = the best value-for-money AI image model right now.
This nano banana review confirms it’s perfect for quick content generation, viral creative scenes, and professional editing. For precise, complex multi-image tasks, you’ll need a few retries.
