Google AI Studio has released Gemini 2.5 Flash Image (codename nano-banana), the most advanced image generation and editing model from Google, featuring high speed and outstanding performance across multiple rankings. Summary generated by Mars AI. This summary was produced by the Mars AI model and its accuracy and completeness are still being iteratively improved.

Google's latest

Do you still remember the mysterious AI image editing model "nano-banana" that was widely discussed before? Back then, it caused quite a stir in the LMArena large language model arena with its outstanding performance. Google Gemini’s top tech experts also took turns to tease the public on social media, and it was even rumored to be the legendary Gemini 3.0 Pro.

Now, Google has finally unveiled its mystery.

In the early hours of August 27 (UTC+8), Google AI Studio officially released Gemini 2.5 Flash Image (codename nano banana) 🍌.

This is Google's most advanced image generation and editing model to date. Not only is it incredibly fast—almost a "lightning" experience—but it has also achieved SOTA results on multiple leaderboards, and is far ahead on LMArena.

In its technical blog, Google mentioned that Gemini 2.0 Flash had already won the favor of developers with its low latency and high cost-effectiveness, but users have always expected higher quality images and more powerful creative control. Gemini 2.5 Flash Image comes with these major upgrades: character consistency is finally fully maintained, prompt-based image editing is more precise, multi-image fusion is natural and smooth, and with its understanding of real-world knowledge, it is not just a model, but more like the "origin" that lays the foundation for the next generation of blockbuster applications.

GeekPark was also among the first to experience it. Unexpectedly, this is not just a model update—it’s the first time you can truly feel that the future of AI photo editing is right before your eyes.

At first, I just wanted to have a routine experience, to "see how much faster the new model is." But unexpectedly, just a few hours of experience made me feel as if I had a glimpse of what the next generation of blockbuster apps will look like.

In the past, we were used to tools like MeituPic, where you could quickly beautify a photo with a few button clicks and a filter. But Gemini 2.5 Flash Image feels completely different. It’s unbelievably fast and smart, like a designer who understands your thoughts. You just need to say the effect you want, and it can present the image in a few seconds.

01 Ultra-fast Generation, Results in Seconds

The most intuitive aspect of the nano banana experience is its speed. In the past, even with a decent computer, using some open-source models would take tens of seconds or even longer from entering a prompt to generating a decent image. For mobile users, this waiting process was even more torturous.

But Gemini 2.5 Flash Image has directly lowered this threshold to just a few seconds. It is Google's self-proclaimed "latest, fastest, and most efficient" native multimodal model, and it’s clear that a lot of effort has gone into optimization. In my actual test, I entered a prompt and got results in about three or four seconds, with resolution and detail both quite clear. (UTC+8)

This experience is very much like using MeituPic to process photos: click the "beautify" button and the effect is almost instant. The difference is that MeituPic uses algorithms to apply filters, while Gemini 2.5 Flash Image builds an image from scratch or makes major modifications to a photo according to your needs. This "point and shoot" satisfaction is unimaginable compared to the tedious photo editing processes of the past.

If speed solves the experience pain points of traditional photo editing users, then "native multimodality" solves the boundaries of AI image capabilities.

Gemini 2.5 Flash Image can not only generate images, but also understand both text and image inputs at the same time. This means I can give it a photo and a text prompt together, and it will combine the information from both to understand exactly what I want.

For example, I uploaded a street photo and told it, "Change the background to a night view of Shinjuku, Tokyo." It not only recognized the subject in my uploaded photo, but also accurately cut out the person and replaced the background with the neon-lit streets of Shinjuku. Even more impressive, it maintained the unity of lighting and shadow on the person, completely avoiding the "hard cut-and-paste" effect that often occurs with manual cutouts.

This level of understanding reminds me of a feature that phone manufacturers have often highlighted in their built-in photo albums in recent years—"one-click background replacement." The difference is, the old background replacement often had blurry edges and mismatched lighting, making the effect look fake. Now, Gemini 2.5 Flash Image can use world knowledge and visual understanding to fill in these details, resulting in much more natural outcomes and far more accurate detail retention than traditional text-to-image/image-to-image model tools.

This is also why I think it will redefine the photo editing experience: no longer relying on a lot of manual adjustments, but using the model’s natural semantic understanding to "brute force" complete the task, especially in scenarios like portrait editing where image detail requirements are extremely high.

For such portrait image processing needs, Gemini 2.5 Flash Image’s character consistency truly provides an unprecedented "Vibe Photoshoping" experience.

This experience breaks many people’s previous impression of AI image generation—"mysticism": if your prompt is good, the output is stunning; if your prompt is mediocre, the result may be completely off.

But in Gemini 2.5 Flash Image, I found that this "mystical feeling" has been greatly reduced. Its understanding of prompts is more precise and closer to user intuition—which is why many people suddenly find it much more usable.

For example, I told it "blur the background, highlight the foreground person," and a few seconds later the generated image was exactly what I wanted; I asked it to "change the person in the photo to a smiling expression," and not only did the corners of the mouth lift slightly, but even the eyes were adjusted, with great attention to detail; I even tried "colorize this black-and-white photo," and the resulting color image wasn’t just random coloring, but tried to match the color atmosphere that should be in a historical photo.

This "say it and it’s done" ability reminds me of using MeituPic in the past, when I just wanted to smooth the skin, but the whole face turned into a "level 10 beauty filter" fake face. Now, Gemini 2.5 Flash Image’s operations are precise and restrained—it really understands what you want and tries to restore it as much as possible.


02 Enhanced Capabilities, Hard to Go Back

To be more intuitive, I deliberately compared it with the mobile photo editing tools I use daily.

On Snapseed, if I want to blur the background, I usually need to spend a minute or two manually selecting the foreground area and then adjusting the blur level. Even if you’re skilled, you can’t avoid repeated modifications.

On MeituPic, although there is a one-click background blur function, it often blurs the edges of the person, making the effect unnatural.

But on Gemini 2.5 Flash Image, I just need to say a sentence, and it automatically recognizes the boundaries between the person and the background, with natural blur and no need for further touch-ups.

Google's latest

This comparison actually illustrates one point: Gemini 2.5 Flash Image frees users from complex operations and hands more work over to the model. For ordinary people, it lowers the threshold for photo editing; for professionals, it saves a lot of time.

After experiencing it, my biggest feeling is that Gemini 2.5 Flash Image is no longer just a photo editing tool, but more like an "intelligent assistant."

In the past, when we used MeituPic, we were using a collection of preset functions—filters, beautification, mosaic—each button corresponding to a function. All you had to do was select bit by bit, adjust step by step, until satisfied.

Now, Gemini 2.5 Flash Image’s logic is completely different. It no longer requires you to learn the logic of the tool, but directly understands your needs. You just say it, and it does it for you.

This change may seem subtle, but it fundamentally changes the relationship of the photo editing process. Before, we adapted to the tool; now, the tool adapts to us. This way of interaction is itself the prototype of the next generation of applications.

From today’s perspective, Gemini 2.5 Flash Image is still in its early stages, and there may still be boundaries in its functions. But the speed, understanding, and fidelity it demonstrates are enough to fill people with imagination for the future.

What would it be like if it were combined with MeituPic? Maybe you open the app, say to your phone, "Help me touch up this photo, make the skin look more natural," and the result is generated in a few seconds (UTC+8); maybe when taking travel photos, you tell it, "Change the weather to sunny," and the photo instantly becomes bright and sunny; or even in video editing, you can change the atmosphere of an entire clip with a single sentence.

That’s why I think it will quickly revolutionize the current workflow of photo editing tools and define the next generation of "MeituPic": not just photo editing, but reshaping the way we interact with image processing, making AI your post-production photography partner.

But at present, Gemini 2.5 Flash Image is not yet ready to serve as an out-of-the-box mass-market photo editing app: not only because its main purpose is still image generation rather than fine-tuning existing images, but also because all images created or edited through Gemini 2.5 Flash Image will contain a SynthID digital watermark for social content platforms to identify AI-generated content.


03 The Tipping Point of a Blockbuster

Looking back, the reason MeituPic once became a national app was that it solved the problem everyone wanted to solve in the simplest way—making photos look better.

And Gemini 2.5 Flash Image goes a step further, refining complex AI capabilities into a "seconds-to-image" experience that everyone can use.

The moment I first said "help me blur the background," and the image was naturally processed in a few seconds, I knew in my heart: this is the tipping point for a blockbuster app. It’s not just a model, but the underlying capability for countless new products in the future.

Maybe a few years from now, we’ll forget the codename Banana, but we’ll see more and more image processing tools that let you "just say what you want, and it’s done instantly"—and maybe, like MeituPic back in the day, they’ll become a shared memory for a generation of users.

Only this time, AI will push our imagination even further.
