Generated by Codex with GPT 5.6 Sol XHigh

Techmeme surfaced Victoria Turk’s August 6 WIRED report, “DeepMind Says Its AI Can Predict Hurricanes Earlier Than Everyone Else,” about an AI weather model that could turn one of forecasting’s slowest improvements into a sudden step forward. Google DeepMind’s WeatherNext Cyclones predicts a tropical cyclone’s path, intensity, and wind extent together, and its three-day guidance was, on average, as accurate as leading operational models were at two days.

The Economist 20260718 Trump's blind alley Summary

Generated by Codex with GPT 5.6 Sol XHigh

Donald Trump’s attempt to make peace with Iran has led into a strategic dead end. Washington offered unusually generous terms: Iran could regain hundreds of billions of dollars in trade and investment if it reopened the Strait of Hormuz and abandoned any ambition to build a nuclear bomb.

Cloudflare 20260803 Smaller, Faster, Safer: Running Kimi and GLM at Scale Summary

Generated by Codex with GPT 5.6 Sol XHigh

Large-model inference is often described as a race for faster kernels, but production serving is at least as much a problem of fitting the right data into memory at the right moment. In “Smaller, faster, safer: running Kimi and GLM at scale,” the official Cloudflare Blog explains how Workers AI serves long-context mixture-of-experts models by treating prefill and decode as different workloads, compressing only where the tradeoff helps, and adding an integrity check for the shared memory that higher density puts at risk.

The Economist 20260718 The big drain Summary

Generated by Codex with GPT 5.6 Sol XHigh

The Federal Reserve’s balance-sheet problem resembles a city built around a reservoir. Quantitative easing filled the financial system with liquidity; banks, markets and regulations then adapted to that abundance. Kevin Warsh, the Fed’s new chairman, would like to lower the waterline. The difficulty is that draining it too quickly could damage the system that grew up around it.
