Best explained

Why larger networks tolerate unstructured architectures: as network scale grows, the model has enough capacity to compensate for suboptimal structure, but at small scale tight architectural choices are critical for performance.

Stigma around the Fed's discount window and standing repo facilities leads banks to hoard reserves at the start of each day rather than rely on intraday liquidity, inflating aggregate reserve demand.

By the numbers

Liquid Neural Networks can perform autonomous car driving with 19 neurons, parallel parking with 12 neurons, and drone navigation with 30 neurons.

The Bank of England's CHAPS liquidity savings mechanism has been estimated to cut the reserve balances needed for payments by 20 to 30 percent.

New today — Sharp calls

Sierra's engineering interview now gives candidates $150 in token budget to build an app using any coding agent and tools of their choice.

Hand-tuned gating mechanisms used in popular efficient architectures like Mamba are architecturally unnecessary; automated search eliminates them entirely in favor of a simpler double gated convolution.

The data center construction pipeline is approximately 3x the entire institutional core real estate index, which stands at $280 billion.

New today — Watchlist

CXMT, a Chinese memory supplier on the Pentagon blacklist, is being petitioned by Apple for a purchase waiver, making it a company to watch in the AI supply chain and export control space.

Tool watch

Liquid AI's AFMD automated architecture search produced the double gated convolution as the optimal efficient architecture, eliminating hand-tuned gating from models like Mamba and gated delta nets.
