The paper introduces Skill2Env, a framework that generates executable environments from skills by using agent capability demands to create task blueprints with objectives, challenges, and evaluation criteria. It also proposes Iterative Task Hardening to improve task difficulty based on solver execution evidence, leading to improved agent performance across benchmarks.
The chart will appear after repeat observations. The current metric comes from the source.

Useful for creating challenging, executable environments to train agents on tasks requiring multi-step interactions and tool use.
This paper introduces a method to enhance large language models' (LLMs) ability to learn from context by using perturbed public documents. The approach involves rewriting documents, generating reasoning-based questions, and training a student model on these synthetic samples, leading to improved performance on CL-bench and broader transfer to tasks like long-context understanding and reasoning.
2 days agoDaily PapersThis paper explores the use of coding agents to automate task and motion planning (TAMP) by generating programs that generalize across problem instances. The agents, using large language models like Claude Code (Opus 5) and Codex (GPT-5.6 Sol and GPT-6 Astra), outperformed traditional planners and baselines in simulated environments with varying object counts, showing higher success rates and lower computational costs.
5 days agoDaily PapersThe paper explores the linearity in Large Language Models (LLMs) by showing that combining inputs from different text streams leads to a superposition of next-token distributions. It suggests that this linearity is an inherent property of the Transformer architecture and can be restored through fine-tuning, allowing for generating two coherent continuations from one forward pass.

The approach reduces the reconstruction-generation gap by improving robustness to layer fusion choices, achieving higher PSNR and lower generation FID scores without modifying the pretrained encoder.

It uses a pyramid Top-K selection strategy to efficiently identify relevant keys, reducing computational cost compared to traditional methods.
4 days agoDaily PapersThis paper reviews memory mechanisms in autoregressive (AR) video generation, focusing on how historical information influences future generations despite limited context windows. It organizes the literature through five perspectives: forms, functions, operations, learning, and evaluation, highlighting challenges like resource-aware memory architectures and standardized evaluation.
