Google DeepMind Launches Nano Banana 2 Lite Image Model and Gemini Omni Flash Video Tools for Developers

Think about how many images you scroll past in a day — product photos, social media graphics, promotional banners. Behind an increasing number of those, there’s an AI model working at speed. Google DeepMind’s latest releases are designed to make that process faster and cheaper still, and they’re available right now to any developer with an API key.

On 30 June 2026, Google DeepMind announced two new models via its official @GoogleDeepMind account: Nano Banana 2 Lite (formally known as Gemini 3.1 Flash-Lite Image) and Gemini Omni Flash (gemini-omni-flash-preview). Both are aimed squarely at developers building products at scale, and both are accessible through the Gemini API and Google AI Studio.

What Is Nano Banana 2 Lite?

Nano Banana is Google’s name for the image generation capabilities built into the Gemini family of models. Nano Banana 2 Lite is the fastest and most cost-efficient option in that family — Google’s own words, not marketing spin. It replaces the earlier Nano Banana model (gemini-2.5-flash-image) and is designed for situations where you need a lot of images, quickly, without breaking the budget.

The headline number is four seconds per image. That’s roughly 2.7 times faster than the previous Gemini 3.1 Flash Image model, according to Google’s documentation and independent technical reviews. For a developer building a product mock-up tool or an advertising platform that generates hundreds of image variants a day, that difference adds up fast.

At the same time, the model handles text-to-image generation, editing existing images, and blending multiple images together — all within a single multimodal model that can also return text alongside images. Output resolution goes up to 4K, with support for at least 14 different aspect ratios, though the default is 1K. Third-party analyses put the API pricing at around $0.0336 per 1K-resolution image, though Google has not yet published clear UK-specific pricing in GBP, so anyone budgeting in sterling should verify figures directly through Google Cloud’s UK billing before committing.

Google is also rolling Nano Banana 2 Lite into its own consumer products. If you use Google Search’s AI Mode, the Gemini app, NotebookLM, Google Photos, Stitch, Google Flow, or Google Ads, you may already be encountering it without realising.

Enter Gemini Omni Flash: Video Generation with Conversational Editing

The second announcement is arguably the more striking one. Gemini Omni Flash is a multimodal video generation and editing model that Google first introduced conceptually at Google I/O, and has now made available to developers in public preview.

What sets it apart is the conversational editing approach. Rather than generating a video and accepting whatever comes out, developers and users can refine the output through natural language — essentially describing what they want changed, and iterating from there. Inputs can combine text prompts, images, and existing video clips.

Pricing sits at around $0.10 per second of generated video, which Google says is on a par with Veo 3.1 Fast. That’s roughly 8p per second at current exchange rates, though as with the image model, confirmed GBP pricing through Google Cloud UK has not yet been clearly documented in public UK price tables.

The Broader Picture

Google isn’t alone in offering tiered AI model pricing — fast and cheap versus slower and higher quality. But the speed and accessibility of Nano Banana 2 Lite, combined with Gemini Omni Flash’s conversational video editing, do represent a meaningful step in making AI-generated media easier to produce at volume.

Not everyone is comfortable with that direction. Some observers have raised concerns about the potential impact on creative jobs, the risk of misleading or deepfake content at scale, and whether safeguards like Google’s SynthID watermarking are sufficient when these models are embedded across consumer products used by millions. Those are legitimate questions, and they don’t disappear just because the tools are impressive.

Small businesses and individual creators using AI-generated images or video in public-facing materials should also be aware of UK advertising standards and consumer protection rules. The Advertising Standards Authority has been clear that AI-generated content is not exempt from existing rules around misleading advertising, so compliance matters regardless of how the image was made.

What This Means for Kent Residents

For developers, creative agencies, and small businesses here in Kent — whether you’re in a Maidstone marketing firm, a Folkestone e-commerce start-up, or a Canterbury tourism operation — Nano Banana 2 Lite and Gemini Omni Flash are available now through Google AI Studio with no regional restrictions noted. They offer a practical, lower-cost route to producing images and video content at scale, though anyone planning to spend real money should wait for confirmed GBP pricing from Google Cloud’s UK billing before building a budget around USD figures. Broader questions about AI-generated content, data governance, and intellectual property remain relevant for any UK business putting these tools to commercial use.
