AI Gets Faster and Cheaper

OpenAI and Google launched new lightweight models today. GPT-5.3 Instant cuts hallucinations by 26.8% in search mode, while Google's Gemini 3.1 Flash-Lite responds 2.5x faster at just $0.25 per million input tokens. Both models now power complex autonomous agents more effectively.

Major Business Moves

Anthropic hit $19B in annual revenue, nearly matching OpenAI's $20B. Accenture acquired Ookla for $1.2B to expand AI-driven network services. Google folded robotics firm Intrinsic into core business to accelerate physical AI.

Critical Security Alert

A vulnerability called ClawJacked exposes locally hosted AI agents to attacks from malicious websites. Hackers already used Claude and ChatGPT in a Mexican government breach. New indirect prompt injection attacks are actively weaponized in the wild, manipulating AI decisions through hidden web content.

Infrastructure Race Heats Up

NVIDIA invested $4 billion in optical networking leaders Lumentum and Coherent to power AI's supply chain. Nokia partnered with Google Cloud to make networks self-healing using AI agents.

Hardware Milestone

Apple released M5 MacBook Pro models emphasizing local AI capabilities.
