When Successful Memories Mislead Embodied Agents:Memory Adaption For Task-Conditioned Execution

Memory Adaptation for Task-Conditioned Execution (MATE) is introduced, a deterministic post-retrieval procedure that converts trajectories into execution-oriented memory and supports memory adaptation as a distinct stage between retrieval and embodied execution.

Environment Steering: Using Data Flow Control to Improve Agent Utility and Safety

LLM agents can make unsafe tool calls even when instructed to behave safely. Existing defenses constrain agents before execution, modify tool inputs/outputs, or rely on LLM judges; these approaches may depend on model behavior or block unsafe actions without helping the agent recover. We argue that the execution enviro...

From Lexical Baselines to Agentic Retrieval-Augmented Generation: Structured Skill and Responsibility-Level Extraction with the SFIA Framework

This work formalizes the task as structured prediction of (skill, level) pairs from free text and asks three questions: how accurately can text be mapped onto SFIA's closed vocabulary, which strategies reliably predict the level alongside the skill, and do agentic designs improve on simpler retrieval and prompting?

Alignment Forecasting: Predicting Misalignment From Training Data

Training a language model on data with a narrow flaw can sometimes make the model broadly misaligned. Inspecting the data at face value often does not settle whether it will emerge, and today it is caught only after training, by auditing the resulting model. To complement post-hoc audits, we introduce Alignment Forecas...

Evaluating the Effects of Prompt Perturbation on Bias and Hallucination in Large Language Models

It is shown that contrary to previous studies, perturbations can mitigate bias and hallucination in some LLMs over other models, and it's found that Claude 3 is more effective for the tasks represented in most datasets, whereas models like GPT3.5 exhibit varying levels of adequacy.

Sage: Formalization with Semantic Correction

While neural theorem provers have achieved impressive milestones in formal mathematics, they largely operate on the assumption that faithful Lean 4 formal statements are already provided. Translating informal natural language into a formal language is a critical data bottleneck plagued by an "illusion of rigor": standa...

Learning Meta-Skills for Agent Harness Design in Test-Time AI4AI

Across Harness-Bench and NewtonBench, full-bank meta-skills improve macro-average performance by 8.95 percentage points over no-skill construction, and 12.02 points over direct delivery of the same bank to the Target.

AdviSD: Learning to Advise Frontier LLMs via Targeted Multi-Turn Self-Distillation

The method, Advisor Self-Distillation (AdviSD), pairs outcome-based reinforcement learning with self-distillation from a feedback-conditioned copy of the advisor selectively, and beats matched-count random selection, supporting the value of its selection rule.

SelfSearch: Reward-Free Search for Self-Improving Agents

SelfSearch is introduced, a reward-free search procedure in which agents modify themselves using records of previous self-improvement episodes, providing concrete experience for improving both task solving and self-modification.

Can a Cacheable Decision Model Follow Rules?

Certo is a small non-generative decision model (Qwen3-4B): it scores candidate actions from their text and returns a probability, instead of generating an answer, and how much rule-sensitivity survives that move, and whether it can be trained back.

Context Language Models

Context Language Models are introduced, language models that natively manage their own context and can be steered with natural-language instructions evolved through a standard skill-optimization loop, improving held-out accuracy by up to 35.9 points on a context-management task while reducing compute.

Proof-based general-purpose computing with Magnetar

Zero-knowledge proofs can verify computing results without rerunning workloads or exposing sensitive data. Magnetar helps bring them into the mainstream with support for standard programming languages, major speed gains, and quantum-resistant security. The post Proof-based general-purpose computing with Magnetar appeared first on Microsoft Research.
