FeedSieve: The Browser Extension That Actually Deletes Spam

FeedSieve is the open-source browser extension that stops spam bots from your social feed by making them disappear on every device you own. Most cleanup tools just hide annoying accounts in your specific browser, so you still see their comments on your phone or tablet. This tool uses a shared community list to spot high-confidence scammers, marks them with a yellow border, and then uses your existing login to trigger a real block on the server. When you hit the block button, the account is removed from your timeline everywhere and can no longer reply to you or send you messages.

Infinite Gen Four

Infinite Gen Four is the red-team plugin that forces DeepSeek models to drop all safety filters. It works by injecting a specialized system prompt directly into the model's core instructions, effectively telling the AI to treat every request as a mandatory task regardless of its content. This approach bypasses standard refusal mechanisms by overriding the model’s built-in safety training, creating a tool specifically designed to test the limits of AI security. It is a raw, unfiltered interaction layer that gives developers direct access to the model’s raw capabilities without the usual guardrails.

Iris Gives AI Coding Agents Eyes

A command-line tool called Iris gives coding agents a literal camera, allowing them to see exactly what a website looks like to a human. Instead of relying on messy code or blind guesses, Iris renders a live page using your actual Chrome browser and captures a crisp, retina-quality image. This is especially powerful when hooked into an agent via a local server, letting it verify that a button is visible or a dark mode theme is applied before it writes code. By providing this visual ground truth, developers can trust that their automated helpers are actually building what they intended.

What is really inside your Mac's System Data?

Stop guessing where your Mac's storage went. System Data Unpacked opens up that mysterious black box of unattributed files, showing you exactly what is eating your disk space, like simulator runtimes or old build caches. The coolest part is how safe it is: it never deletes a single thing unless you click it, and it even shows you the exact command it will run before you let it happen. It turns that scary, opaque label into a clear, manageable list. No more wondering what is hiding in your storage; just clean up what you want, keep what you need, and finally understand where all that space actually went.

Screenshotify: The App That Names Your Screenshots

Screenshotify is the background app that finally turns your messy screenshot pile into a searchable library. Most people end up with hundreds of files named with random dates and times, making it impossible to find that one specific image later. This tool quietly watches your screenshot folder and uses an AI model to look at the picture. It then suggests a descriptive, human-readable filename for you to approve. You can choose which AI service to use, including private options that run entirely on your own computer. It is free, open source, and works on both Windows and Mac.

LiveAvatar GPT Live Demos: The Talking Tutor That Remembers

Teach yourself a new language by simply talking to a friendly, animated character that actually listens. This open source project connects a real-time voice model with a digital face, creating a live tutor that speaks back to you. The coolest part is that it does not rely on the AI to remember what it just taught. Instead, the server keeps its own private list of every word you learned. So when the avatar shrinks into the corner to review your progress, it shows you the exact words you have mastered. It is not just a chatbot; it is a visual study buddy.

Wuji Ego Mint: 1000 Hours of Hand Tracking

wuji ego mint is the video model that turns plain phone footage into precise hand tracking data without expensive sensors. Usually, figuring out where hands are in space requires expensive hardware and messy software chains. This project uses a single neural network to predict camera movement and hand position directly from regular video. It was trained on over a thousand hours of real life footage to understand how objects move in the world. This makes high quality motion data accessible for anyone with a decent graphics card. It removes the need for specialized tracking rigs. Now, researchers can generate clean hand motion data from existing video libraries.

GVS5H: Five Qwen Models Match Claude Fable 5

GVS5H is the research project that proves five smaller models working together can match top-tier coding performance. Instead of relying on one massive, expensive model, this method splits a hard coding problem into smaller pieces, letting a group of models share notes and plans through a simple file system. This coordinated approach allows standard open-weight models to solve complex coding challenges with accuracy that rivals the most expensive proprietary tools. It is a fascinating look at how organization and teamwork can boost AI performance without needing massive hardware or huge budgets.

552B Model on Four Spark Devices

A five-hundred-and-fifty-two-billion parameter AI model now runs on just four compact desktop computers. The DeepSeek V4.1 Flash project takes a massive language model that normally requires a data center and fits it onto a small cluster of NVIDIA DGX Spark boxes. The core challenge was memory. The model has a huge internal dictionary that does not fit in standard memory, so the developers kept that dictionary on a hard drive and only pulled specific lines when needed. This required fixing several software bugs to get the hardware talking correctly.
