Nano Banana AI in Google Lens & NotebookLM: Live Status
As of now, Nano Banana AI is not a single, unified feature that appears in both Google Lens and NotebookLM. Instead, “Nano Banana� is the nickname for Google’s latest image generation model, Gemini 2.5 Flash Image, which is being rolled out across several Google products, including NotebookLM and, in a limited form, Google Lens. The model is live in NotebookLM for all users, while its integration into Google Lens is currently available only to a subset of Android users in the Google app, not to everyone.
What Exactly Is “Nano Banana�?
The nickname “Nano Banana� comes from a demo where the model was asked to draw a banana, and it produced a photorealistic, high-quality image. The name stuck internally and then leaked to the public. It is not an official product name; the official name is Gemini 2.5 Flash Image. It is a multimodal model, meaning it can take both text and image inputs and generate images as output. Unlike earlier image generators that worked from a separate prompt, this model can understand a conversation, remember previous edits, and apply consistent style across multiple images in a single session.
Where It’s Live: NotebookLM
In NotebookLM, Nano Banana is fully rolled out. When you open a notebook, you’ll see an “Create image� option in the toolbar. You can describe an image in natural language, and the model will generate it. The key difference from older tools is that you can then ask for changes conversationally: “Make the sky more orange,� or “Add a dog.� The model keeps the context of the previous images, so you don’t have to re-describe everything from scratch. It also supports uploading a reference image and asking for edits, like “Change the background to a beach.� This is available on the web and in the mobile app, for all users, including those on the free plan (with usage limits).
Where It’s Live: Google Lens
Google Lens is a different story. Lens is primarily an image recognition tool—it identifies objects, text, and landmarks. Nano Banana is an image generation model, so it doesn’t fit Lens’s core function. However, Google has started testing a feature where, after you search with an image in Lens, you can ask to “reimagine� it—for example, “Make this a cartoon� or “Add a rainbow.� That feature uses Nano Banana. As of now, it’s rolling out in the Google app on Android, but only to a small percentage of users. There’s no official timeline for a wider release, and it may not appear on iOS for a while. So if you don’t see it in Lens, that’s expected.
How to Use Nano Banana in NotebookLM (Step by Step)
- Go to notebooklm.google.com and open a notebook.
- Click the “Create image� button in the toolbar (it looks like a small paintbrush or image icon).
- Type a description of the image you want. Be specific: “A red apple on a wooden table, photorealistic, soft lighting.�
- Click “Create.� The image appears in a few seconds.
- To edit, type a follow-up instruction in the same chat box, like “Make the apple green.� The model will modify the last image it generated.
- You can also upload a reference image by clicking the “+� icon and then asking for edits.
That’s it. The generated images are saved to your notebook and can be downloaded or inserted into your notes.
Common Problems and Misconceptions
“It’s not working in Lens.� As mentioned, the Lens integration is a limited test. If you don’t see the “Reimagine� option, you’re not in the test group. It’s not a bug.
“It’s the same as Imagen or DALL-E.� No. Nano Banana is built into Gemini, so it can have a conversation about the image. You can say “Make it more professional� and it understands the context. Older models required you to start over with a new prompt.
“It’s free forever.� NotebookLM’s free tier includes a limited number of image generations per day (around 20–30). If you hit the limit, you’ll need to wait or upgrade to Google AI Pro. The exact numbers change, so check the current limits in your account.
“It can generate any image.� Like all AI image models, it has safety filters. It will refuse to generate images of real people in compromising situations, violent content, or copyrighted characters. If you try, you’ll get an error message.
How It Compares to Other Image Generators
Compared to standalone tools like Midjourney or DALL-E 3, Nano Banana’s main strength is the conversational editing. You can make multiple changes without re-prompting, and it maintains the style across a series of images. For example, you can ask for “a logo for a coffee shopâ€� and then “now make a version with a cat.â€� It will keep the same layout and color scheme. That’s a feature you don’t get in most other tools. On the downside, the image resolution is limited to 1K (about 1024×1024), so it’s not suitable for large prints. Also, it’s not as good at rendering long text in images—like a paragraph of text on a sign—as some competitors.
Costs and Access
Nano Banana is included with NotebookLM at no extra cost on the free tier, subject to daily limits. For higher limits, you need a Google AI Pro subscription (which also gives you access to more Gemini features). There’s no separate fee for the image model. In Google Lens, the reimagine feature, when it rolls out, will be free within the Google app, but again, it’s not widely available yet. For developers, the model is available via the Gemini API, with pricing per image generated—you’d need to check Google’s pricing page for current rates.
Safety and Accuracy Notes
Because Nano Banana can generate realistic images of people, there are potential misuse risks. Google has implemented watermarks on all generated images (invisible, but detectable) and blocks requests that include real people’s faces without consent. You should not use it to create deepfakes or misleading content. Also, the model can make mistakes—it might misspell words or produce anatomical errors (like extra fingers). Always review the output before using it in any professional context. For factual accuracy, remember that the model is trained on internet data, so it may reflect biases or stereotypes.
