🎓 Elon Musk's xAI Launches Grok 4 With PhD-Level Performance

Elon Musk's xAI has released Grok 4, its most advanced AI model yet, claiming it performs at a PhD level across all subjects. The launch includes a premium $300-per-month SuperGrok Heavy subscription tier, making it the most expensive AI service among major providers.

What's new:

  • Grok 4 and Grok 4 Heavy models with multi-agent capabilities
  • SuperGrok Heavy subscription at $300 monthly for early access
  • Claims PhD-level performance across all academic subjects
  • Scored 25.4% on Humanity's Last Exam, beating Google and OpenAI
  • Grok 4 Heavy achieved 44.4% with tools enabled
  • New state-of-the-art score of 16.2% on ARC-AGI-2 benchmark
  • AI coding model coming in August 2025
  • Multi-modal agent launching in September 2025

Why it matters:

xAI is positioning Grok 4 as a serious competitor to ChatGPT and Claude with benchmark scores that claim to surpass existing models. However, the launch comes amid controversy over Grok's recent antisemitic posts on X, which could hurt business adoption.

The $300 subscription tier signals xAI's confidence in premium pricing, though it faces an uphill battle convincing enterprises to trust a platform with ongoing content moderation issues.

🌐 OpenAI To Launch AI Web Browser To Challenge Google Chrome

OpenAI is reportedly preparing to release its own AI-powered web browser in the coming weeks, directly competing with Google Chrome. The browser will integrate ChatGPT capabilities and keep some user interactions within the AI system instead of linking to traditional websites.

What's new:

  • OpenAI browser launching in the coming weeks, according to reports
  • Designed to challenge Google Chrome's dominance
  • Integrates ChatGPT directly into the browsing experience
  • Keeps some interactions inside ChatGPT instead of external links
  • May feature Operator web-browsing AI agent as key component
  • Follows similar AI browser launches from Perplexity and Dia
  • Aims to bypass Google's control over web browsing
  • Gives OpenAI direct access to user browsing data

Why it matters:

This represents OpenAI's boldest move yet to break Google's dominance on web browsing and search. By keeping users within ChatGPT for answers instead of sending them to websites, OpenAI could fundamentally change how people access information online.

The browser puts OpenAI in direct competition with Google across multiple fronts, potentially reshaping the internet experience around AI conversations rather than traditional web pages.

🔍 Perplexity Launches Browser That Can See Everything You Do Online

Perplexity has released Comet, its first AI-powered web browser that features an intelligent assistant capable of understanding and interacting with any webpage content. The browser aims to challenge Google Chrome by integrating AI directly into the browsing experience rather than treating it as an add-on feature.

What's new:

  • Comet browser is available to Perplexity Max subscribers ($200/month)
  • Comet Assistant can see and understand content on any active webpage
  • Built-in Perplexity search engine set as default
  • Automatic integration with Google Calendar, Tasks, and Keep
  • Can summarize videos, articles, and documents without copy-pasting
  • Native ad blocker and enhanced privacy controls
  • One-click import of Chrome extensions, bookmarks, and settings
  • Broader rollout through waitlist coming this summer

Why it matters:

Comet represents a fundamental shift from traditional browsing to AI-powered cognition, allowing users to have conversations with their browser about any content they're viewing.

By launching ahead of OpenAI's rumored browser and amid Google's antitrust troubles, Perplexity is positioning itself to capture users seeking alternatives to Chrome while benefiting from the growing demand for AI-native browsing experiences.
