Human experiments demonstrate that AssistanceZero effectively reduces user actions and exhibits emergent behaviors such as digging foundations, inferring roofs, and learning from corrections.
- Can RLHF be More Efficient with Imperfect Reward Models? A Policy Coverage Perspective
-
This work identifies a structural property induced by KL regularization in RLHF—the policy coverage over the optimal policy is bounded by its sub-optimality (\(\text{Cov}^{\pi^*|\pi} \leq 1 + \kappa \cdot (J(\pi^*) - J(\pi))/\beta\)). Based on this, two transfer learning principles are proposed: (1) selecting a transfer policy with high policy value, and (2) self-transfer distilling the policy from online data. The proposed TPO algorithm achieves a regret of \(O(W\sqrt{T})\) in the early stage and \(O(\sqrt{T})\) in the late stage. It can be modularly integrated with DPO/IPO/XPO, and its effectiveness is validated on the T5 summarization task.

- Communicating Activations Between Language Model Agents
-
A method is proposed to allow LLM agents to communicate via intermediate layer activations (instead of natural language) by injecting the activation vector of Model A into the intermediate layers during the forward pass of Model B.

It analyzes the deficiencies of evaluation methods from 2019 to 2025 and calls for the establishment of standardized multilingual benchmarks and interdisciplinary approaches.
- Correlated Errors in Large Language Models
-
Through a large-scale empirical analysis of over 350 LLMs, this paper reveals highly correlated error patterns across different LLMs. When both models make mistakes, they choose the same incorrect answer in approximately 60% of cases, and more accurate models exhibit higher correlation. Furthermore, the paper investigates the downstream impacts of this correlation on LLM-as-Judge evaluation and the labor market.

- Mixture of Lookup Experts
-
MoLE (Mixture of Lookup Experts) is proposed, which modifies the input of routing experts in MoE from intermediate features to embedding tokens. This allows experts to be reparameterized into lookup tables (LUTs) and offloaded to storage devices before inference, thereby achieving inference speeds and memory footprints comparable to dense models while maintaining MoE-level performance.
- MoH: Multi-Head Attention as Mixture-of-Head Attention
-
This paper reformulates Multi-Head Attention (MHA) into a summation form and proposes Mixture-of-Head Attention (MoH) inspired by MoE. By utilizing a router to dynamically select the most relevant subset of attention heads for each token, MoH satisfies or even surpasses standard MHA performance while activating only \(50\% \sim 90\%\) of the heads. It also demonstrates that pre-trained models (such as LLaMA3-8B) can be successfully converted into MoH models via continue-tuning.
