When AI Designs AI: Innovation or Imitation?

The paper investigates whether large language model (LLM) agents can design AI methods that outperform or differ from human-designed approaches. By mapping both human- and agent-designed methods into task‑specific algorithmic design spaces, the authors evaluate performance and algorithmic differences across multiple modalities. Results show that while agents occasionally match or exceed human state‑of‑the‑art performance, 96.8% of their designs fall within human‑derived spaces, often recombining or exactly matching existing human algorithms.

When Search Becomes Memory: Accelerating Robot Design Discovery with Self-Evolving Skills

The paper introduces Auto‑Robotist, a self‑evolving large language model (LLM) agent that transforms evolutionary robot design search traces into an explicit natural‑language skill library. Each skill records a structural archetype, evidence‑grounded rules, and supporting designs, enabling the agent to retrieve and condition LLM edits during search while still using a genetic algorithm for exploration. Experiments on seven EvoGym tasks show that Auto‑Robotist outperforms standard genetic algorithms, especially when transferring learned skills to larger design spaces.

TO-Agents: A Multi-Agent AI Framework for Subjective Preference-Guided Topology Optimization

TO-Agents is a multi‑agent AI framework that translates natural‑language design intent into iterative topology optimization. It converts a human problem description into solver inputs, runs the optimizer, renders 3D topologies, and employs a judge agent to critique and revise results using multiview vision‑language reasoning. Evaluated on a cantilever beam and a phone‑stand design, the system achieved preference‑aligned designs in 60% of trials, outperforming an ablated pipeline by up to six times and enabling end‑to‑end intent‑to‑prototype design with additive manufacturing.

OR-Agent: Bridging Evolutionary Search and Structured Research for Automated Heuristic Design

OR-Agent is a multi‑agent research framework that automates heuristic design for optimization problems by structuring heuristic search as a tree‑based workflow with explicit hypothesis generation and systematic backtracking. It introduces a hierarchical, optimization‑inspired reflection system that uses short‑term reflections as verbal gradients, long‑term reflections as verbal momentum, and memory compression as semantic weight decay to guide research dynamics. Experiments on classical combinatorial optimization tasks and simulation‑based cooperative driving scenarios show that OR‑Agent outperforms strong evolutionary search baselines, with all code and data publicly available.
