🦾 Grok 4 - beast mode

Hey folks,

An AI-generated version of U.S. Secretary of State, Marco Rubio has been sliding into Signal chats pretending to be the real person, and it worked. The AI imposter managed to reach foreign ministers, a governor, and even a member of Congress, all using fake voice and text messages. The goal was probably to access sensitive info but with voice clones getting more convincing by the day, this kind of attack might become the new phishing email.

Let’s dive in..

🦾 Grok 4: xAI’s New Benchmark Beast

🐝 The Buzz: xAI just dropped Grok 4 alongside a specialized Grok 4 Code variant, marking its boldest move yet with these models outpacing OpenAI’s GPT-4o and Google’s latest offerings across reasoning, coding, and multimodal benchmarks.

• Dual-model strategy: Grok 4 targets general users, while Grok 4 Code zeroes in on developers with enhanced coding needs, an approach that splits xAI’s lineup to rival both ChatGPT and GitHub Copilot at once.

• Benchmark domination: Early leaks show Grok 4 crushing GPT-4o on logic and math tests, and surpassing Gemini in few-shot reasoning tasks.

• Beating o3: Independent results peg Grok 4 well ahead of OpenAI’s o3 model on advanced reasoning benchmarks, underlining xAI’s rapid evolution.

• Coding ace: The Grok 4 Code variant delivers 10–20 percent faster code generation than its predecessor, thanks to architecture tweaks and specialized training data.

• Speed boost: A performance report indicates Grok 4 runs over 200 percent faster inference than Grok 3, slashing response times for complex queries

• Multimodal & agentic: Beyond text, Grok 4 handles images and plugins, spawning “agentic” workflows that can invoke tools, browse the web, and execute code snippets on demand.

💡 Takeaway: Grok 4 is xAI’s moonshot, carving out ground in both general AI and dev tools. If it lives up to these leaked numbers, it could redraw the landscape for who leads the generative-AI charge.

💻️ OpenAI’s Browser: The Tab You Didn’t Know You Needed

🐝 The Buzz: OpenAI is gearing up to drop its own AI-powered web browser in the coming weeks, aiming to wrestle control of your browsing data from Google Chrome’s massive grip. Built on Chromium, it promises to keep you in a chat-based interface that can book reservations or fill out forms on your behalf. If it lands as reported, this browser could be the keystone in OpenAI’s plan to weave its services into every corner of your digital life.

• ChatGPT in your address bar: The new browser will integrate AI agents directly into tabs, so you can ask follow-ups, summarize pages, or get recommendations without switching apps.

• Data as the new ad currency: With Chrome handling over two-thirds of global market share, OpenAI’s browser gives it a front-row seat to user behavior and undercutting Google’s ad empire by tapping the same insights

• Task automation on tap: Expect features that let AI complete chores like booking flights or filling forms, moving beyond mere search into full-blown digital assistant territory

• Built on familiar foundations: Since it’s Chromium-based, you’ll still get Chrome extensions and speedy page loads, just with an AI co-pilot under the hood.

💡 Takeaway: If you’ve ever wished browsing was like 1000 open tabs, OpenAI’s browser could be your new go-to. But carving into Chrome’s 3 billion user base won’t be easy, so expect a bumpy beta as it fights for your clicks and data.
