Artificial intelligence
Week in a nutshell. A heavy launch week. OpenAI shipped GPT-6.1 Terra (cheaper, better computer use), Google DeepMind released both the Genie 4 world model and its new frontier model Gemini 4 Carbon, and Anthropic showed Claude doing drug-discovery work. Safety was the other big story: both OpenAI and Anthropic published new ways of monitoring their own models for misuse and bad behaviour.
DeepMind's Genie 4 generates explorable, interactive 3D worlds with sound in real time.

Macroeconomics
Week in a nutshell. Inflation is back. The Fed held at 3.75–4.00% on 28 Oct, but it was a "hawkish pause": markets now price roughly a 75% chance of a December hike. The ECB also held at 2.50% with a December hike widely expected, and Lagarde announced she will step down early. US tech stocks sold off hard on 30 Oct. Closer to home, the RBNZ kept the OCR on hold, and NZ economist Michael Reddell questioned how much attention it is paying to oil rather than core inflation.
Nasdaq 100 fell nearly 5% in one day on 30 Oct, as midterm election odds shifted.
