The Quantum AI Digest: 12 August 2025 Daily Dispatch

From NVIDIA’s “Physical AI” push at SIGGRAPH—Cosmos Reason, Omniverse updates, and Blackwell robotics—to OpenAI’s GPT‑5 launch and pricing shake‑up, this episode unpacks the model race, Apple’s delayed super‑Siri and platform skirmishes, Reddit’s data lockdown, and GitHub’s shake‑up. We cover AI’s real‑world impact (Heineken’s efficiency gains, NASA’s “space doctor”), Tesla FSD and the Dojo pivot, Perplexity’s audacious Chrome bid, and a new U.S. “chip tax” on exports to China. Plus: open‑source leaps, agent tooling, security risks, funding, and research breakthroughs from brain prediction to drug design.
