AI Analysis

Chollet argues that while AI has 10x'd code quantity shipped by developers, net productivity (value per unit time) has barely increased because the additional code solves incremental problems and creates its own problems.

The quantity of code that devs ship has roughly 10xed. But net developer productivity (value created by unit of time) is only up by a bit, if at all. Part of it is that the additional code is solving more incremental problems. A bigger part is that the new code is creating problems of its own.

AI Analysis

Following up on yesterday's Social discussion of UK AISA findings, Mollick references Wait But Why's famous AI growth cartoon and cites independent assessments from METR and UK's AISA suggesting we are past the inflection point of exponential AI capability growth.

Everyone has seen the @waitbutwhy cartoon of AI capability growth with a "you are here" indicator just before the exponential really starts, but the independent assessments of both METR and the UK's AISA do seem to show that we are past that point now (until we hit a slowdown?) t.co/vxYc6GSS5d

Clement Delangue announces Datadog's Toto 2.0, a family of open-weight time series foundation models (4M to 2.5B params) showing scaling laws work for time series — first across BOOM, GIFT-Eval, and TIME benchmarks.

Are scaling laws finally working for time series foundation models? Today, @datadoghq is releasing Toto 2.0 weights in Apache 2.0 on @huggingface. It's a family of open-weights TSFMs from 4M to 2.5B parameters, where every size beats the last from a single hyperparameter config. First across the leading benchmarks: BOOM, GIFT-Eval, and TIME. Most TSFM families ship multiple sizes that all perform roughly the same. This one doesn't. Why it matters: scaling laws gave language and vision a predi

AI Analysis

Detailed technical explanation of a novel memory module that runs parallel to frozen LLMs, maintaining per-layer matrices updated via gradient descent that provide context-dependent corrections to attention computations - distinct from LoRA-style static adapters

The paper proposes a memory module that runs in parallel with a frozen language model rather than living inside its context window or in a separate retrieval database. At each transformer layer where the module is inserted, it maintains a small matrix — eight by eight in their main setup — that gets updated as new tokens stream in, using a single gradient descent step on a small regression problem at each position: given a learned key vector, predict a learned value vector, and write back the p
