osworld task_demonstration **OSWorld** is a first-of-its-kind scalable, real computer environment for multimodal agents, supporting task setup, execution-based evaluation, and interactive learning across operating systems. It can serve as a unified environment for evaluating open-ended computer tasks that involve arbitrary apps (e.g., task examples in the above Fig). We also create a benchmark of 369 real-world computer tasks in **OSWorld** with reliable, reproducible setup and evaluation scripts.

Abstract

Autonomous agents that accomplish complex computer tasks with minimal human interventions have the potential to transform human-computer interaction, significantly enhancing accessibility and productivity. However, existing benchmarks either lack an interactive environment or are limited to environments specific to certain applications or domains, failing to reflect the diverse and complex nature of real-world computer use, thereby limiting the scope of tasks and agent scalability. To address this issue, we introduce **OSWorld**, the first-of-its-kind scalable, real computer environment for multimodal agents, supporting task setup, execution-based evaluation, and interactive learning across various operating systems such as Ubuntu, Windows, and macOS. **OSWorld** can serve as a unified, integrated computer environment for assessing open-ended computer tasks that involve arbitrary applications. Building upon **OSWorld**, we create a benchmark of 369 computer tasks involving real web and desktop apps in open domains, OS file I/O, and workflows spanning multiple applications. Each task example is derived from real-world computer use cases and includes a detailed initial state setup configuration and a custom execution-based evaluation script for reliable, reproducible evaluation. Extensive evaluation of state-of-the-art LLM/VLM-based agents on **OSWorld** reveals significant deficiencies in their ability to serve as computer assistants. While humans can accomplish over 72.36% of the tasks, the best model achieves only 12.24% success, primarily struggling with GUI grounding and operational knowledge. Comprehensive analysis using **OSWorld** provides valuable insights for developing multimodal generalist agents that were not possible with previous benchmarks.

OSWorld Environment Infrastructure

environment infrastructure The **OSWorld** environment uses a configuration file for initializing tasks *(highlighted in red)*, agent interaction, post-processing upon agent completion *(highlighted in orange)*, retrieving files and information *(highlighted in yellow)*, and executing the evaluation function *(highlighted in green)*. The corresponding configuration items are highlighted in colors that match their respective components within the environment. Environments can run in parallel on a single host machine for learning or evaluation purposes. Headless operation is supported.

Data Statistics and Comparison

Below we present an overview of the main statistics of **OSWorld**, showcasing the outline and a broad spectrum of tasks. **OSWorld** contains a total of 369 tasks (and an additional 43 tasks on Windows for analysis).

Benchmark

We adopt state-of-the-art LLM and VLM from open-source representatives such as Mixtral and CogAgent, and closed-source ones from GPT, Gemini, and Claude families on **OSWorld**, as LLM and VLM agent baselines. We also explore methods such as the Set-of-Marks aided approach, which has been demonstrated to improve spatial capabilities for visual reasoning. **We are actively updating the benchmark with new LLMs, VLMs and methods. Pull requests welcomed!**

Analysis

We conduct a qualitative analysis in the aspect of models, methods, and human to find out factors influencing the performance of VLMs in digital agent tasks and their underlying behavioral logic. We investigate the impact of task attributes (such as difficulty, feasibility, visual requirement, and GUI complexity), input measurements (such as screenshot resolution, the influence of trajectory history, and the effect of UI layout), and explore whether there are patterns in the agent's performance across different operating systems. Here is an overview of our analysis outcome.
