    xAI Launches Grok Bot, Always-On AI Teammates With Their Own Cloud Computer
    • xAI opened Grok Bot in early beta on August 11 — persistent agents that sign into your tools, drive them like a human, and keep working after you close the laptop.
    • Each Bot gets its own dedicated cloud computer; runtime runs on Cursor infrastructure via a joint distribution deal.
    • Access is gated to SuperGrok Heavy ($300/mo), Cursor Ultra ($200/mo), and Cursor Teams Premium ($120/seat); Mac, iOS, Windows, and Linux at launch, Android later.
    • Bloomberg framed it as xAI's clearest shot at OpenAI and Anthropic; HN pushback centered on handing an Elon-Musk-owned service login credentials for mail, CRM, and vendor accounts.

    OpenAI Ships GPT-5.6-Cyber, Which Already Found Two Chrome V8 Zero-Days
    • OpenAI expanded Daybreak on August 11 with two tiers — Blue (GPT-5.6 Sol without cyber guardrails) and Red (the new GPT-5.6-Cyber for exploit validation and red teaming).
    • GPT-5.6-Cyber answered 95% of advanced cybersecurity prompts vs 1.5% for GPT-5.6 Sol under standard safeguards.
    • The model turned up two chainable memory-corruption bugs in Chrome's V8 engine; Google fixed one as CVE-2026-15903.
    • Access is limited to vetted defenders and researchers; The Hacker News flagged the reduced-refusal posture as the most consequential shift.
