Evaluates LLMs as autonomous agents across 8 distinct environments (OS, DB, KG, DCG, LTP, HH, WS, WB) using a standardized Task Interface that defines sample retrieval, execution, and metric calculation. The framework abstracts environment-specific logic behind a common contract, enabling systematic comparison of agent performance across heterogeneous task types with environment-specific startup times (5s-5min) and resource requirements (500MB-15GB). Agents interact with tasks through multi-turn Session management that tracks conversation history and message exchange.
Unique: First benchmark framework specifically designed for LLM agents (not just language tasks) with 8 diverse environments spanning command-line, database, knowledge graphs, games, and web interaction. Uses standardized Task Interface abstraction to enable environment-agnostic agent evaluation while preserving environment-specific metrics and startup characteristics.
vs alternatives: Broader environment coverage than HELM (which focuses on language tasks) and more systematic than ad-hoc agent evaluation, with standardized interfaces enabling reproducible comparison across heterogeneous task domains.
Provides a contract-based Task interface that all benchmark environments implement, defining methods for retrieving sample indices, executing individual samples with agent interactions, and calculating overall performance metrics. The interface abstracts environment-specific logic (game engines, database systems, web simulators) behind common method signatures, enabling the framework to orchestrate agent evaluation without coupling to particular environment implementations. Each task environment implements sample retrieval, step-by-step execution with agent actions, and metric aggregation.
Unique: Uses a minimal but comprehensive Task interface contract (get_indices, execute, get_metrics) that abstracts away environment-specific complexity while preserving the ability to implement domain-specific logic. Enables 8 diverse environments (game engines, databases, web simulators) to coexist under a single evaluation framework.
vs alternatives: More flexible than monolithic benchmarks like GLUE (which hardcode specific tasks) because new environments can be added by implementing a single interface, not by modifying core evaluation logic.
Provides a web shopping task environment where agents interact with a simulated e-commerce platform to complete shopping tasks (product search, comparison, purchase). Agents navigate product catalogs, read descriptions and reviews, manage shopping carts, and complete transactions through a web interface. The environment simulates realistic e-commerce workflows with product filtering, price comparison, and checkout processes.

Provides a household task environment where agents complete domestic tasks in a simulated home environment (based on ALFWorld). Agents interact with a text-based or visual home simulator, manipulating objects, navigating rooms, and completing household chores (cooking, cleaning, organizing). The environment simulates realistic household physics and object interactions, requiring agents to reason about spatial relationships, object properties, and task decomposition. Tasks evaluate agent capabilities in embodied reasoning, multi-step task planning, and interactive problem-solving.
Unique: Integrates a household task simulation (ALFWorld-based) into AgentBench, enabling agents to complete domestic tasks requiring spatial reasoning, object manipulation, and multi-step planning. Agents must understand household physics and decompose complex chores into executable actions.
vs alternatives: More embodied than text-only task planning because agents must reason about spatial relationships and object interactions, but more abstract than visual embodied AI because it uses text descriptions rather than images.
Provides a lateral thinking puzzle task environment where agents solve puzzles requiring creative, non-linear reasoning and constraint satisfaction. Agents interact with a puzzle system that presents scenarios, accepts guesses/hypotheses, and provides feedback on correctness. The environment manages puzzle state, constraint tracking, and solution validation. Tasks evaluate agent capabilities in creative problem-solving, hypothesis generation, constraint reasoning, and iterative refinement. Agents must think beyond obvious solutions and reason about implicit constraints.
Unique: Provides a lateral thinking puzzle environment that tests agent capabilities in creative, non-linear reasoning and constraint satisfaction. Puzzles require agents to think beyond obvious solutions and reason about implicit constraints, testing higher-order reasoning.
vs alternatives: More challenging than standard reasoning benchmarks because lateral thinking puzzles require creative hypothesis generation and constraint reasoning, not just logical deduction.
Provides a digital card game task environment where agents play strategic card games requiring decision-making, resource management, and opponent modeling. Agents receive game state information (hand, board, opponent state), select actions (play cards, attack, defend), and observe game outcomes. The environment manages game rules, turn order, win conditions, and card interactions. Tasks evaluate agent capabilities in strategic reasoning, resource optimization, and decision-making under uncertainty. Agents must balance multiple objectives and adapt strategies based on game state.
Unique: Provides a digital card game environment that tests agent capabilities in strategic reasoning, resource management, and decision-making under uncertainty. Agents must evaluate multiple card options and adapt strategies based on evolving game state.
vs alternatives: More complex than simple turn-based games because card games introduce resource constraints, card interactions, and strategic depth, testing more sophisticated reasoning than single-action decisions.
Provides a configuration system that enables users to define task environments, agent parameters, and evaluation assignments through YAML or JSON configuration files. The configuration system abstracts away code-level customization, enabling non-developers to set up benchmarks by editing configuration files. Supports task-specific parameters (environment type, sample count, resource limits), agent-specific parameters (model, temperature, prompt template), and assignment-level parameters (worker count, timeout). Configuration validation ensures correctness before execution.
Unique: Provides a configuration-driven setup system that separates benchmark specification from code, enabling non-developers to set up evaluations and researchers to share reproducible configurations. Supports task, agent, and assignment-level configuration.
vs alternatives: More accessible than code-based setup because configuration files are human-readable and don't require programming knowledge, but less flexible than programmatic APIs for advanced customization.
