概览

Crab 是一个开放的框架,用于设计和运行基准环境,以测试 LLM‑based 代理的能力。它采用以 Python 为中心的方式,让开发者用熟悉的工具定义任务、环境和评估逻辑,而不是使用专门的配置语言。 该框架面向多环境代理评估,支持代理必须在不同应用或系统之间协同行动的场景。这使其在研究人员和工程师研究代理推理、规划和工具使用时,能够在真实且可控的条件下进行实验。 通过标准化基准的构建与测量方式,Crab 致力于使代理评估更可复现、且更易于扩展新任务、指标以及模型后端。

主要功能

  • 基于 Python 的基准和任务定义
  • 跨环境代理评估
  • 可配置的任务图和指标
  • 可插拔的 LLM 后端
  • 可复现的实验工作流
  • 支持多步骤代理动作

I've evaluated a lot of these over the years. What stands out here is configurable task graphs and metrics — handled better than most — and useful for reproducible agent research. Smaller ecosystem than mainstream eval frameworks is my one real gripe. Worth the time if this is your use case.

I've evaluated a lot of these over the years. What stands out here is python-based benchmark and task definitions — handled better than most — and python-native API lowers the barrier to building benchmarks. Requires Python and ML engineering knowledge is my one real gripe. Worth the time if this is your use case.

I've evaluated a lot of these over the years. What stands out here is pluggable LLM backends — handled better than most — and useful for reproducible agent research. Requires Python and ML engineering knowledge is my one real gripe. Worth the time if this is your use case.
