MIT Study: How Self‑Generated History Pollutes LLM Context and Degrades Multi‑Turn Chats

An MIT paper reveals that storing a language model’s own prior replies—known as context pollution—significantly lengthens the dialogue context while offering little quality benefit, with up to a ten‑fold reduction in tokens and comparable responses for about 70% of turns, especially in open‑source models.

New March 2026 Paper Exposes Fraudulent Third‑Party APIs for Large Language Models

A recent arXiv study audited 17 popular shadow APIs used in 187 papers, finding up to a 47.21% performance gap versus official models—e.g., Gemini‑2.5‑flash’s accuracy drops from 83.82% to about 37% on MedQA—highlighting serious reliability and safety risks of unofficial LLM services.

Measuring Multivariate Distribution Differences with Energy Distance

Energy Distance is a statistical metric that quantifies how far two multivariate probability distributions diverge by comparing cross‑distribution and within‑distribution Euclidean distances, and it can be combined with permutation testing to assess the significance of observed shifts.

Why Energy‑Based Models Could Outperform Probabilistic LLMs, According to Yann LeCun

Yann LeCun argues that the probability‑driven, token‑by‑token design of current large language models may never reach human‑level intelligence, and explains how Energy‑Based Models replace probability distributions with an energy function, offering more flexible training, inference, and multi‑modal capabilities.
