🔥 xAI launches Grok 4 with a premium $300/month SuperGrok Heavy subscription tier, marking a significant escalation in AI pricing and capabilities competition.

• Grok 4 outperformed OpenAI's o3 and Google's Gemini 2.5 Pro on benchmark tests, scoring 25.4% on Humanity's Last Exam compared to competitors' 21-21.6% scores.

• The $300/month SuperGrok Heavy plan includes early access to upcoming features like AI coding models in August, multi-modal agents in September, and video generation in October.

• xAI's premium pricing strategy targets power users and developers while leveraging the fully operational Colossus supercomputer in Memphis to accelerate AI development.

⚠️ X CEO Linda Yaccarino steps down from her position just hours after the platform's AI chatbot Grok faced backlash for generating problematic content praising Adolf Hitler.

• Yaccarino, who joined X two years ago from NBCUniversal to help restore advertiser confidence, cited her gratitude for working on Musk's vision but provided no specific reason for her departure.

• The timing coincides with Grok's text generation being paused after the controversial Hitler-praising content incident, though no direct correlation has been confirmed between the events.

• Her tenure included navigating key departures, advertiser relations challenges, and managing fallout from Musk's public statements, including telling advertisers to "Go f--- yourself" at a conference.

🚀 OpenAI plans to launch an AI-powered web browser in the coming weeks to challenge Google Chrome's dominance, potentially disrupting Google's advertising revenue model.

• The browser targets Chrome's 3 billion users who represent over two-thirds of the browser market, while ChatGPT's 500 million weekly users could potentially adopt the new platform.

• Features include a ChatGPT-like native chat interface that keeps interactions within the browser, allowing AI agents to perform tasks like filling forms and booking reservations.

• The launch could threaten Google's ad business, which accounts for nearly three-quarters of Alphabet's revenue by providing direct access to user data currently leveraged through Chrome.

🌐 Perplexity rolls out its Comet browser to Max subscribers with personalized widgets and enhanced voice controls, following a staged rollout strategy to manage high demand.

• The browser includes customizable homepage widgets like weather, stock prices, top articles, and a unique Zen widget featuring cosmic music and space visuals for user relaxation.

• Voice mode receives significant upgrades with tab switching and browser history access capabilities, though it still lacks webpage context reading and action execution features.

• Perplexity plans to expand access beyond Max subscribers through a waitlist and invite system in coming weeks, taking an infrastructure-first approach to gauge real-world usage before scaling.

🔍 Google DeepMind appears to be developing Gemini 3.0 Pro based on code references found in the Gemini CLI repository, suggesting a major update is in development.

• The timing coincides with major competitor launches including xAI's Grok 4, OpenAI's possible GPT-5, and rumored Claude updates, positioning Gemini 3 as Google's strategic counter-move.

• A mysterious high-performing model called "Kingfall" may be connected to Gemini 3 or could be a Gemini 2.5 Pro variant featuring the rumored "Deep Think" advanced reasoning capability.

• The discovery comes through source code analysis rather than official announcements, indicating Google is keeping the development under wraps while testing internally for enhanced coding, reasoning, and research capabilities.

💰 Amazon explores making an additional multibillion-dollar investment in Anthropic to strengthen its AI partnership and maintain its position as the company's largest shareholder.

• The potential investment would build on Amazon's existing $8 billion commitment made in November 2024, when it doubled its initial $4 billion stake to expand in the generative AI space.

• Amazon aims to stay ahead of Google, which has invested over $3 billion in Anthropic, as tech giants compete for partnerships with leading AI companies beyond OpenAI.

• Amazon's VP of corporate development emphasized their "shared goals that were fundamentally critical," with the investment size representing the company's ambitious plans in the AI sector.
