📲 ChatGPT launches new App Store

PLUS: How to generate high-quality images using pre-built Nano Banana Pro prompts

Good morning! OpenAI just launched the ChatGPT App Store, a major step towards turning ChatGPT into an everything app and Google made Gemini 3 Flash the default model worldwide. Plus, you’ll get access to hands-on Nano Banana Pro prompt library for high-quality images.

In today’s AI newsletter:

  • OpenAI just launches ChatGPT App Store

  • Google launches Gemini 3 Flash

  • China’s secret EUV chip push exposed

  • How to generate high-quality images using pre-built Nano Banana Pro prompts

  • 4 new AI tools worth trying

AI NEWS

OpenAI introduced an App Directory and opened its SDK, allowing developers to build interactive apps that run directly inside ChatGPT’s interface — no switching tabs required.

  • Apps like Spotify, Apple Music, Zillow, and DoorDash now work natively inside ChatGPT

  • Apps can search files, sync data, or run deep research within conversations

  • Developers can build, distribute, and later monetize apps via ChatGPT

  • Apps may use Memory (if enabled) to personalize experiences

This pushes ChatGPT beyond a chatbot into a platform layer, where users interact with services through conversation instead of apps or browsers, putting OpenAI closer to becoming the “App Store of AI.”

AI MODELS

Gemini 3 Flash is Google’s new “workhorse” AI model, designed for speed, multimodality, and large-scale everyday tasks, while rivaling frontier models on key benchmarks.

  • Now the default model in the Gemini app and AI Mode in Search worldwide

  • Matches or beats Gemini 3 Pro and GPT-5.2 on select reasoning and multimodal benchmarks

  • Strong at video, audio, images, sketches, and visual answers with tables and graphics

  • Available to developers via API, Vertex AI, and Gemini Enterprise at low-cost pricing

By making a fast, near-frontier model the default, Google is prioritizing scale and usability over raw power, signaling that everyday AI speed and cost efficiency, not just benchmarks, will decide the next phase of the AI platform war.

AI RACE

China has developed a working prototype of an extreme ultraviolet (EUV) lithography machine, a technology long monopolized by ASML and central to advanced AI chips.

  • Prototype EUV machine built in Shenzhen by former ASML engineers, completed in early 2025

  • Machine can generate EUV light but hasn’t produced working chips yet

  • Government targets working chips by 2028, though insiders say 2030 is more realistic

  • Huawei coordinates a nationwide effort involving thousands of engineers and state labs

EUV lithography is the single biggest choke point in advanced AI chips. If China cracks it, US export controls lose their strongest leverage, reshaping the global AI, defense, and semiconductor power balance for decades.

HOW TO AI

🗂️ How to generate high-quality images using pre-built Nano Banana Pro prompts

In this tutorial, you’ll learn how to use the Nano Banana Pro Prompt Hub to generate professional-quality images without writing prompts from scratch.

đź§° Who is This For

  • Creators who want high-quality portraits, avatars, and visuals

  • Designers who need fast inspiration, mockups, or ready-made visual styles

  • Founders and marketers creating images for landing pages, ads, and presentations

  • Beginners who want professional-grade AI images without trial and error

STEP 1: Access the Nano Banana Pro Prompt Hub

Open your browser and go to YouMind. Once the page loads, you’ll see a bold header at the top labeled Nano Banana Pro Prompts.

Directly below it is a large input box where you can generate images, and underneath that is a section called Fresh Prompts.

On the right side of this section, there’s a yellow counter showing the total number of available prompts, which is well over a thousand and continuously updating. This page is the central hub where all pre-built Nano Banana prompts live.

STEP 2: Browse and Filter Prompt Styles

Scroll down into the Fresh Prompts section. Here, you’ll notice category tabs such as Profile / Avatar, Social Media Post, Infographic. Clicking on any of these filters instantly narrows the prompt library to that specific use case. Each prompt appears as a card with a preview image, a title, the creator’s name, and a short description, allowing you to visually judge the style before opening it.

This makes it easy to find a cinematic, realistic, watercolor, anime, or minimal design style without guessing.

STEP 3: Copy and Customize a Prompt

When you find a prompt card you like, click on it and make sure the PROMPT tab is selected, not the ORIGINAL tab. Inside the card, you’ll see a black-bordered text box containing the full optimized prompt. Highlight and copy the entire text exactly as it appears.

Before generating, quickly scan the prompt to identify the subject description. Replace any existing subject, such as a famous person or generic placeholder, with your own subject while keeping the rest of the prompt intact. This ensures you preserve the lighting, composition, and stylistic instructions that make the prompt work so well.

STEP 4: Generate Your Image in Nano Banana Pro

Once your prompt is customized, scroll back to the top of the page and paste it into the main input field that says “Describe the image you want to generate…”.

Alternatively, you can open Nano Banana Pro in a new tab if you prefer a clean workspace. When you’re ready, hit enter. Within moments, Nano Banana Pro will produce a high-quality image using the pre-optimized prompt, giving you professional results without trial and error.

OpenAI has held preliminary discussions with investors about raising tens of billions of dollars, and as much as $100B, at a valuation of around $750B.

Amazon's AGI team lead, Rohit Prasad, is leaving at the end of 2025; AWS SVP Peter DeSantis will lead a group combining AI, silicon, and quantum computing teams.

Google is working on a new initiative to make its AI chips run PyTorch better and is working closely with Meta, as the two discuss Meta using more TPUs.

Google brings its vibe coding tool Opal to Gemini on the web, letting users create their own custom AI-powered mini apps, called Gems, which can be reused later.
