Embodied-BenchForge: A Closed-Loop Agentic Workflow... | AI Research

Embodied-BenchForge is an agentic framework designed to automate the creation of embodied AI benchmarks. While previous methods for building these benchmarks often relied on manual labor or were limited to specific environments, this system transforms user-defined evaluation goals into complete, high-quality benchmark artifacts. By integrating a closed-loop process that combines forward synthesis with backward verification and repair, the framework ensures that the resulting benchmarks are reliable, consistent, and capable of testing complex model behaviors.

How the Approach Works

The framework operates through a process called "Closed-Loop Benchmark Synthesis." It uses a library of reusable "skills"—such as data collection, environment structuring, and code generation—to build benchmarks. These skills are organized into a hierarchical workflow that tracks how different parts of a benchmark depend on one another. The same large language models question is explored in Efficient Test-Time Adaptation through Human-AI Interaction, which adds a research perspective.
To ensure quality, the system applies "Requirement-Guided Verification and Repair." Every piece of the benchmark is checked against specific contracts (such as structural, semantic, or execution requirements). If a component fails these checks, the system uses its recorded history to identify the exact source of the error. It then performs a local repair or rolls back to an earlier stage, reconstructing only the affected parts rather than discarding the entire project.

Two Tracks of Evaluation

Embodied-BenchForge produces two distinct types of benchmarks:

• Offline EQA Track: This track includes six benchmarks covering various robotic platforms, including household robots, autonomous vehicles, robotic arms, UAVs, and quadruped robots. These benchmarks focus on observation-based understanding, such as answering questions based on visual or spatial evidence.

• Interactive Embodied Track: This track features 220 executable tasks set in simulated household environments. Unlike static benchmarks, these tasks provide a restorable initial state, an action interface, and a terminal-state verifier, allowing researchers to evaluate how well an agent performs in a closed-loop, interactive setting.

Results and Reliability

Evaluations of various multimodal large language models and embodied agents demonstrate that these benchmarks effectively distinguish between different levels of model capability. The results highlight a significant performance gap between a model's ability to understand observations and its ability to successfully execute tasks in a closed-loop environment. Quality assessments, which included both automated judge models and human annotators, confirmed that the benchmarks are well-aligned with user intent and maintain high standards for grounding and consistency. Furthermore, the framework’s ability to perform localized repairs and reuse construction skills proves to be an efficient way to manage the complexity of building diverse, large-scale embodied benchmarks.
