Daily AI News Digest: Apple vs. OpenAI, Anthropic's Secret Mythos, Grok Build, & AI Markets

Welcome to today's AI briefing! 🚀 The tech world is bracing for a potential legal showdown as OpenAI reportedly considers a breach of contract notice against Apple. OpenAI is dissatisfied with ChatGPT's integration in iOS, which has failed to drive expected premium subscriptions, while Apple simultaneously courts Google Gemini and Anthropic's Claude to power Siri. Speaking of Anthropic, the company has developed a frontier AI model named "Mythos" that is so advanced at autonomously discovering zero-day software vulnerabilities that it is being withheld from public release to prevent misuse. The AI cybersecurity arms race is escalating rapidly; in response, OpenAI launched the 'Daybreak' initiative, combining models like GPT-5.5-Cyber with Codex to help defenders detect and patch vulnerabilities at machine speed. This urgency is underscored by the new "Mini Shai-Hulud" worm, a massive supply chain attack that just compromised over 170 developer packages across Mistral AI, Guardrails AI, and TanStack. In the developer space, Elon Musk’s xAI has officially entered the coding agent race with Grok Build. Now in early beta for SuperGrok Heavy subscribers, this terminal-based tool runs multiple parallel AI sub-agents to plan and build code autonomously. Meanwhile, Google is transforming Android into an 'agentic' operating system, announcing that Android 17 will feature proactive 'Gemini Intelligence' capable of completing multi-step tasks across your apps. Finally, despite crude oil prices surging above $106 a barrel due to geopolitical tensions in the Strait of Hormuz, the AI boom continues to defy gravity, pushing US equities to record highs as investors double down on AI infrastructure.
