Scalable Memory vs. Reasoning in AI Models
By
–
The key distinction: scalable memory ≠ scalable reasoning. A model can store evicted context in fixed-size fast weights and still fail if it has not spent enough computation transforming that context into a useful state. That is why the “sleep” phase is interesting: it moves

Gary Marcus reaffirms his neuro-symbolic AI stance from 2001
By
–
J'ai en effet dit tout cela, et j'ai littéralement des milliers de preuves, remontant à mon livre de 2001 et à mon célèbre article *Deep Learning is Hitting a Wall* qui plaidait fortement pour compléter l'apprentissage profond avec des outils neuro-symboliques. Veuillez lire mon

Functional vs Distributional Geometry in Hierarchical Concept Spectral Analysis
By
–
The key distinction here is subtle but important: Functional geometry asks what a representation can do. Distributional geometry asks where that representation came from. This paper shows that at least part of hierarchical concept geometry can be explained by the spectral

Semantic structure vs. function: A caution for mechanistic interpretability
By
–
The line that stayed with me: semantic structure may be useful for function without being driven by function. That is a powerful caution for mechanistic interpretability. Some beautiful structures inside models may be less like “designed concepts” and more like the linear

Paper: Semantic Hierarchies Are Geometric in Language Models
By
–
What looks like ontology may be eigenspectrum. A beautiful new paper by Andres Nava and Matthieu Wyart gives a mechanistic account of one of the most striking facts about language models: semantic hierarchies appear geometrically. An owl is a bird.
A bird is an animal.

AI Latency for Cloud Robotics and Edge Embodiment
By

Agreed: Latency is now low enough to support robot inference in the cloud, and edge is where embodiment transforms and safety checks should be performed: https://

MiniMax M2 Technical Report: Attention Mechanism Analysis
By
–
The MiniMax M2 series was one of the most widely used open-weight LLM series earlier this year. Now, we got a technical report with some interesting tidbits. I summarized some of them below: 1. Full attention as an anti-trend?: They tried hybrid sliding-window attention

AI advantage from faster leaner systems, not better prompts
By
–
The next AI advantage won't come from a better prompt. It'll come from a faster, leaner system underneath the model. Her's Law and the Tau Scaling Law framework are worth understanding deeply if you're making AI infrastructure decisions. @huawei is leading this thinking. What
