1. Google DeepMind overhauled its leadership as Demis Hassabis stepped back from day-to-day management to become Alphabet's chief scientist, Jeff Dean left Google to launch AI startup Discovery Loop, and former DeepMind CTO Koray Kavukcuoglu was named to lead the unit.

2. Google announced it would shut down Google Assistant on Android and Wear OS starting September 4, 2026, and designated Gemini as the AI-powered successor across smartphones, tablets, watches, and Android Auto.

3. US appeals court allowed Perplexity's AI shopping agents to return to Amazon by overturning Amazon's injunction and ruling that users, not the startup, accessed Amazon, establishing a federal appeals precedent for AI agents acting on online platforms.

4. Mistral released Shieldstral, a 3-billion-parameter open safety model that used natural-language yes-or-no checks, matched models seven times its size on some benchmarks, and supported operator-defined runtime criteria and local deployment.

5. SpaceX outlined plans to increase compute capacity by more than fivefold by the end of 2027, estimated that the expansion could require over one million Nvidia Vera Rubin GPUs, and reported $2.56 billion in Q2 revenue for its AI segment largely from server leasing.
