SFT matches RL if you MCMC the training data first

A paper submitted to arXiv on 1 October 2026 introduces a Markov chain Monte Carlo (MCMC) sampling algorithm that progressively transforms off-policy traces into more on-policy data for finetuning, allowing supervised fi…

Removing Timing Shortcuts Improves Non-Invasive Brain-to-Text

A September 30, 2026 arXiv paper reports that major gains in non-invasive brain-to-text decoding are largely reproducible without any brain data, because fixed-length windows starting at each word implicitly leak word-du…

Scaling Laws for Looped Mixture of Experts

A paper submitted to arXiv on 30 Sep 2026 introduces Loop Scaling Laws, which its authors describe as the first scaling law to jointly model recurrence and sparsity alongside model size and data. The fitted laws predict …

Context Language Models

A paper submitted to arXiv on 29 Sep 2026 introduces Context Language Models (CLMs), language models that natively manage their own context by treating the context as a file the model can update without restriction. Buil…

Distillation Defenses Easily Break After Reinforcement Learning

A September 28, 2026 arXiv paper (2609.35699) argues that distillation defenses for closed-source large language models are typically evaluated immediately after distillation and break once attackers apply reinforcement …
