Researchers present CODE, a novel approach to knowledge editing in large language models that replaces fact overwriting with causal reasoning. By embedding causal narratives and on-policy distillation into model parameters, CODE reduces self-refutation rates from 95.6% to 1.8%, enabling LLMs to evolve knowledge coherently rather than storing isolated facts.
Researchers propose GXPO, a new policy optimization technique for reinforcement learning that approximates multi-step lookahead using only three backward passes instead of many, improving large language model reasoning performance by 1.65-5.00 points over standard GRPO while achieving up to 4x step speedup.
Researchers reveal that large language models develop distinct hierarchical processing stages (Local, Intermediate, Global) determined by architecture family rather than model size. Using information theory, they demonstrate that Llama and Qwen models show dramatically different brittleness patterns across layers, with architectural design — not scaling — as the primary driver of model behavior.
