This Week in Tech: AI, Gadgets & What Matters

Welcome folks! 👋

This week brought a cluster of exciting developments in AI and tech gadgets, from futuristic wearables to new tools that'll change the developer workflow. If you're into smart devices, creative automation, or AI-powered edge tech, here are the top five stories that caught our attention.

1. Gemini CLI: AI in Your Terminal

Google just dropped Gemini CLI, a developer tool that brings natural‑language AI power to your terminal with Gemini 2.5 Pro. Workflows like debugging, content creation, image gen, and web search can all be executed via prompt with a context window up to 1 million tokens.

Best part: a generous free tier with 60 requests/min and 1,000/day. This is a big d­­­­eal for devs automating with CI/CD or Linux tooling.

2. HeyGen Video Agent: Videos from a Single Prompt

With HeyGen's Video Agent, you can now generate entire videos—script, visuals, voiceover, and editing from a simple text prompt. It’s being pitched as the first all‑in‑one creative AI system, potentially replacing entire toolchains used in marketing, e‑learning, or content production. 

3. Gemma 3n: Multimodal AI on Edge Devices

Google’s new model, Gemma 3n, is built to run on low‑end devices, even phones with just 2 GB RAM. It can handle text, image, audio, and video processing all offline. That means fantastically broad AI access, even where connectivity or compute is limited.

4. Samsung Galaxy Galaxy Z Fold 7, Flip 7 & Watch 8 Launch

At Galaxy Unpacked on July 9, Samsung unveiled a trio of new devices packed with AI smarts:

• Z Fold 7: At 8.9 mm folded, it's Samsung’s thinnest foldable yet. It includes a massive 200 MP camera, 8‑inch AMOLED display, Snapdragon 8 Elite chip, and One UI 8 on Android 16 with Google Gemini features like Circle to Search and Writing Assist.

• Z Flip 7 & Flip 7 FE: A 6.9‑inch foldable with larger battery, enhanced personalization (outfit/meal suggestions from your photos), and a smarter cover display. The FE offers a lower‑cost entry under $900.

• Watch 8 Series: Now with Google Gemini on board, offering vascular load estimates, antioxidant level sensors, AI coaching, and an Ultra model with premium tracking features.

5. Xiaomi AI Smart Glasses Debut

Xiaomi just broke into smart eyewear with AR glasses that blend style and affordability. They offer a 12 MP camera, real‑time translation, voice‑activated commands, object recognition, and eight hours of battery life, powered by a Snapdragon AR1 chip for local AI. Priced at ~$280, this could be a turning point in wearable AI adoption, undercutting pricier rivals.

Honorable Tech Mentions

• Grok 4 by xAI: Dual versions launch one for general use, and one tailored for developers, offering speed and flexibility in AI workflows.

• Perplexity’s Comet Browser: An AI-powered browser that summarises search results and brings an AI assistant into your browsing experience.

Why It Matters

With tools like Gemini CLI and HeyGen becoming mainstream, AI is expanding into everyday workflows, from coding to creative production. At the same time, smart devices like foldables and AR glasses are becoming smarter and more accessible.
