Surprise! Apple Announces PQ3 – New Security Protocol for iMessage with iOS 17.4

Surprise! Apple Announces PQ3 – New Security Protocol for iMessage with iOS 17.4

All of a sudden, Apple announced a New Security Protocol for iMessage: PQ3 (A Post Quantum Cryptographic Protocol). It will be available with beta iOS 17.4; however, we’ll witness its complete launch by the last quarter of 2024.

Well, the officials have made this unexpected announcement to ensure more privacy and security in your iPhones. So, let’s see what’s the news!

Apple Announces PQ3 – A Post-Quantum Cryptographic Protocol

Basically, Apple has announced PQ3 to protect iMessage from several quantum attacks. The company has stated PQ3 as a ‘groundbreaking protocol,’ and it’s the 1st one to hit “Level-3 Security”.

Apple has claimed that it is the most robust encryption protocol, which is even stronger than the one available in WhatsApp and Signal.

No doubt, Apple has ensured the security of iMessage since the beginning. Initially, in 2011, it was declared as end-to-end encrypted, and then in 2023, it reached the level of Contact key verification.

What does Apple have to Say about “A Post-Quantum Cryptographic Protocol”

Well, the company has been consistently upgrading the privacy and security measures of iMessage, and via their recent blog post, they came up with a breaking statement;

“Today, we are announcing the most significant cryptographic security upgrade in iMessage history with the introduction of PQ3, a groundbreaking post-quantum cryptographic protocol that advances the state of the art of end-to-end secure messaging. With compromise-resilient encryption and extensive defenses against even highly sophisticated quantum attacks, PQ3 is the first messaging protocol to reach what we call Level 3 security — providing protocol protections that surpass those in all other widely deployed messaging apps. To our knowledge, PQ3 has the strongest security properties of any at-scale messaging protocol in the world.”

Moreover, the PQ3 (A Post-Quantum Cryptographic Protocol) uses Kyber public keys. That mainly enables devices to create encryption keys for some initial texts. And later on, it would integrate a ‘novel post-quantum rekeying’ system for further action.

Furthermore, Mr. Douglas said, “The iMessage PQ3 protocol is a well-designed cryptographic protocol for secure messaging that uses state-of-the-art techniques for end-to-end encrypted communication. In my analysis using the reductionist security methodology, I confirmed that the PQ3 protocol provides post-quantum confidentiality, which can give users confidence in the privacy of their communication even in the face of potential improvements in quantum computing technology.”

PQ3 – Security Protocol for iMessage is rolling out with iOS 17.4

Gradually, the PQ3 will be rolling out along with the official launch of;

Apple hasn’t disclosed that would it be a part of Vision Pro, but we can surely expect it after the initial rollout.

ByteDance Drops UI-TARS-1.5, The AI Agent That Can Control Your Screen

ByteDance Drops UI-TARS-1.5, The AI Agent That Can Control Your Screen

Have you ever wished your computer could just do things for you? Not just answer questions, but actually click buttons, type text, and navigate websites? Well, that dream just got real. ByteDance recently dropped UI-TARS-1.5, a breakthrough AI agent that can see your screen and control it just like you would, with your mouse and keyboard. Most AI assistants can chat with you and maybe set an alarm. UI-TARS-1.5 goes way beyond that; it watches your screen and takes action.

Table of Contents

What is UI-TARS-1.5

UI-TARS-1.5 is an open-source multimodal agent that can look at your screen, understand what it sees, and then take over your mouse and keyboard to get things done. What’s really cool is how it thinks before acting, it plans its moves. Let’s say you ask it to organize your messy desktop files. Instead of just giving you tips, it’ll actually create folders, drag files into them, and even rename things if needed,  all while you sit back and watch the magic happen.

How UI-TARS-1.5 AI Agent Works

The core of UI-TARS-1.5’s abilities lies in its enhanced perception system. Unlike other AI systems that require special access to understand interfaces, UI-TARS-1.5 works by looking at your screen, just like you do.

The agent has been trained on massive datasets of GUI screenshots, allowing it to recognize buttons, text fields, icons, and other interface elements across different apps and websites. It doesn’t need custom integration with each program; it can learn to use virtually any software with a visual interface.

When it looks at your screen, it’s not just seeing pixels; it understands context, identifies interactive elements, and plans how to navigate them to achieve your goals.

Example Tasks Performed by UI-TARS-1.5

The Technology Behind UI-TARS-1.5

It builds on ByteDance’s previous architecture but adds several key innovations:

1. Enhanced Perception: The AI understands context on your screen and can precisely caption what it sees

2. Unified Action Modeling: Actions are standardized across platforms for precise interaction

3. System-2 Reasoning: The agent incorporates deliberate thinking into its decision-making

4. Iterative Training: It continuously learns from mistakes and adapts to new situations

Perhaps most impressive is UI-TARS-1.5’s scaling ability; the longer it works on a task, the better it gets. This shows its ability to learn and adapt in real-time, just like humans do.

UI-TARS-1.5 vs. OpenAI CUA and Claude 3.7

ByteDance didn’t just create another AI agent; they built a record-breaker. In head-to-head tests against the OpenAI CUA and Claude 3.7, UI-TARS-1.5 came out on top:

  • In computer tests (OSworld), it scored 42.5%, while OpenAI CUA got 36.4%, and Claude 3.7 managed only 28%.
  • For browser tasks, it achieved 84.8% success in WebVoyager tests.
  • On phone interfaces, it reached 64.2% in Android World tests.
  • The secret to UI-TARS-1.5’s success? It can spot things on your screen with incredible accuracy. On the challenging ScreenSpotPro benchmark, which tests how well AI can locate specific elements, it scored 61.6%, more than double what OpenAI CUA (23.4%) and Claude 3.7 (27.7%) scored.

What makes these scores even more impressive is that the model gets better the longer it works on something. It doesn’t get tired or bored; it just keeps learning and improving with each step.

Key Tasks Performed by UI-TARS-1.5 AI Agent

1. Daily Computer Tasks

Think about all those repetitive tasks you handle daily: sorting emails, organizing files, updating spreadsheets. UI-TARS-1.5 can take these off your plate by watching and learning how you work.

In one demonstration, it was asked to transfer data from a LibreOffice Calc spreadsheet to a Writer document while keeping the original formatting. The AI handled it flawlessly.

What’s impressive isn’t just that it completed the task; it’s how it handled unexpected situations. When its first attempt to select data didn’t work perfectly, it recognized the problem, adjusted its approach, and tried again until successful.

2. Web Research

While UI-TARS-1.5 wasn’t specifically designed for deep research, it shows remarkable ability to navigate the web and find information. In SimpleQA tests, it scored 83.8, outperforming GPT-4.5’s 60.

Imagine asking, “Find me the latest research on climate change solutions and create a summary document.” It could open your browser, search for relevant information, organize findings, and even create a document with what it learns—all by controlling your computer just like you would.

3. Gaming Tasks

One of the most exciting applications for UI-TARS-1.5 is gaming. ByteDance tested the AI on 14 different games from poki.com, and the results were mind-blowing. It achieved perfect 100% scores across nearly all games tested.

Games like 2048, Snake, and various puzzle games pose no challenge for this AI. What’s even more impressive is that it gets better the longer it plays, learning from each move and refining its strategy.

The ultimate test came with Minecraft. It outperformed specialized gaming AI by a significant margin, successfully mining blocks and defeating enemies while navigating the 3D environment using only visual input and standard controls.

How to Get Started With UI-TARS-1.5

ByteDance has open-sourced this model, making it available for the research community. Developers can access it, which is trained from Qwen2.5-VL-7B. They’ve also released UI-TARS-desktop, an application that lets users experiment with the technology directly. This open approach encourages collaboration and further development from the community.

The Unlimited Benefits of UI-TARS-1.5

UI-TARS-1.5 represents a fundamental shift in human-computer interaction. Instead of you adapting to how computers work, it makes computers adapt to how humans work.

This approach makes AI immediately useful across countless applications without requiring special compatibility. You can use it to create presentations, manage email, organize photos, or fill out tax forms, all using standard software you already own.

For businesses, it could automate countless routine tasks. For individuals, it means having a digital assistant that can take real action instead of just offering advice.

With UI-TARS-1.5, ByteDance has potentially changed how we’ll interact with computers for years to come. As this technology continues to develop, the line between what humans do and what AI assistants do will continue to blur, freeing us to focus on more creative and fulfilling tasks.

Tiny Agents, A 50-Line MCP-Powered AI Framework by HuggingFace Co-Founder for the Modern Dev

Tiny Agents, A 50-Line MCP-Powered AI Framework by HuggingFace Co-Founder for the Modern Dev

Want to build an AI agent without drowning in complexity? Tiny Agents might be exactly what you’re looking for. This minimalist, MCP-powered AI framework, created by the co-founder of HuggingFace, lets you build powerful AI agents with just 50 lines of JavaScript code.

Table of Contents

Introducing Tiny Agents

The magic behind Tiny Agents is surprisingly simple. While exploring the Model Context Protocol (MCP), the HuggingFace co-founder discovered something mind-blowing: once you have an MCP client, creating an agent is just a while loop on top of it.

“Once you have a MCP Client, an Agent is literally just a while loop on top of it,” explains the Hugging Face co-founder behind the project.

This insight led to the creation of Tiny Agents – a lightweight, powerful AI framework that makes building AI agents accessible to more developers.

Understanding MCP

MCP isn’t complicated, but it’s incredibly useful. At its core, MCP is a standard API that lets you connect tools to Large Language Models (LLMs).

Think of it as a universal adapter that helps your LLM talk to various tools and services. The beauty of MCP is that once you understand this standard, you can plug in different tools without changing your core agent code.

Modern LLMs have native support for tool calling (also known as function calling). This means they can understand when to use external tools and how to format the calls correctly. Your LLM can decide to call zero, one, or multiple tools during a conversation.

How Tiny Agents Work

The Tiny Agents framework builds on top of an MCP client, which handles all the complex parts of connecting to MCP servers and managing tools. Here’s what makes it work:

  • It connects to MCP servers to discover available tools
  • It formats these tools so the LLM can understand them
  • It handles the back-and-forth between the LLM and the tools
  • It manages the conversation flow with a simple while loop

The whole agent is built around alternating between tool calling and feeding results back to the LLM. This continues until certain exit conditions are met, like completing a task or needing user input.

The Technical Magic Behind Tiny Agents

Let’s peek under the hood at what makes Tiny Agents work:

1. The McpClient Class

This class is the foundation. It maintains an Inference Client for talking to LLMs, manages connections to MCP servers and keeps track of all available tools. When connecting to an MCP server, it gets a list of tools and formats them for the LLM.

2. The Agent Class

The Agent class extends McpClient and adds a system prompt to guide the LLM, a message history for the conversation, control flow tools like task_complete and ask_question and the all-important while loop that drives the agent.

3. The “50 Line” While Loop

The heart of Tiny Agents is its while loop. This surprisingly simple bit of code processes a single turn with the LLM, checks if any tools were called exits the loop if needed (task completed, question asked, etc.) and continues the conversation by alternating between tool results and LLM responses.

Getting Started with Tiny Agents

Want to try it out? It’s super easy to get going:

npx @huggingface/mcp-client

Or if you’re using pnpm:

pnpx @huggingface/mcp-client

This installs the package temporarily and runs it. You’ll see your agent connect to two MCP servers running locally:

  • A file system server that can access your Desktop
  • A Playwright MCP server that controls a sandboxed browser

Experiment With Tiny Agents

Now, you can ask it to do different tasks. I used it to perform the following task:

File System Operations

Web Browsing & Research

Using Different Models and Providers with Tiny Agents

By default, Tiny Agents uses “Qwen/Qwen2.5-72B-Instruct” as the model and Nebius as the inference provider.

But you can easily configure it to use different models and providers through environment variables:

javascript

const agent = new Agent({

    provider: process.env.PROVIDER ?? “nebius”,

    model: process.env.MODEL_ID ?? “Qwen/Qwen2.5-72B-Instruct”,

    apiKey: process.env.HF_TOKEN,

    servers: SERVERS,

});

Why Tiny Agents Matters

This represents a significant step forward in making AI agents more accessible. By reducing the complexity to just 50 lines of code, it opens the door for many more developers to experiment with and build AI agents.

The framework shows that you don’t need complex architectures to create useful AI agents. With modern LLMs that have native tool-calling abilities, a simple approach can be surprisingly effective.

Build Your Own Tiny Agents Today

The entire Tiny Agents codebase is open source and available in the huggingface.js mono-repo. Whether you’re new to AI agents or an experienced developer, this minimal framework offers a great way to start experimenting with MCP-powered AI agents.

With just 50 lines of code, you can have a working AI agent that connects to tools, maintains context, and solves real problems. It’s a perfect example of how sometimes the simplest solutions are the most elegant.

So why not give Tiny Agents a try? Your first MCP-powered agent is just a few lines of code away.
