Synatra: Turning Indirect Knowledge into Direct Demonstrations for Digital Agents at Scale

NeurIPS 2024poster

LLMs can now act as autonomous agents that interact with digital environments and complete specific objectives (e.g., arranging an online meeting). However, accuracy is still far from satisfactory, partly due to a lack of large-scale, direct demonstrations for digital tasks. Obtaining supervised dat…

VisualWebArena: Evaluating Multimodal Agents on Realistic Visual Web Tasks

ACL 2024long

Autonomous agents capable of planning, reasoning, and executing actions on the web offer a promising avenue for automating computer tasks. However, the majority of existing benchmarks primarily focus on text-based agents, neglecting many natural tasks that require visual information to effectively s…

WebArena: A Realistic Web Environment for Building Autonomous Agents

ICLR 2024poster

With advances in generative AI, there is now potential for autonomous agents to manage daily tasks via natural language commands. However, current agents are primarily created and tested in simplified synthetic environments, leading to a disconnect with real-world scenarios. In this paper, we build…

Hierarchical Prompting Assists Large Language Model on Web Navigation

EMNLP 2023short findings

Large language models (LLMs) struggle on processing complicated observations in interactive decision making. To alleviate this issue, we propose a simple hierarchical prompting approach. Diverging from previous prompting approaches that always put the full observation (a web page) to the prompt, we…
