What it solves

AI agent evaluation often relies on static benchmarks that don't reflect the unpredictability of the real world. This platform provides dynamic, evolving environments where agents must adapt their strategies as new information emerges, requiring multi-step reasoning (often 10+ steps) to complete complex, grounded tasks.

How it works

The system simulates realistic scenarios by combining four core components:

• Agents: AI entities using the ReAct (Reasoning + Acting) framework to interact with the environment.
• Apps: Simulated interactive applications (such as calendars, email, and file systems) that provide APIs for the agents.
• Events: Dynamic triggers that change the environment state over time.
• Scenarios: Integrated tasks that combine apps and events with specific validation logic to measure success.

It includes the Gaia2 benchmark, featuring 800 scenarios across 10 "universes," and a multilingual extension called Omnilingual-Gaia2. It also supports Sequential Gaia2, where agents maintain memory and state across a chain of related scenarios.

Who it’s for

AI researchers and developers building and evaluating autonomous agents who need a rigorous way to test multi-step reasoning, adaptability, and real-world grounding beyond simple prompt-response pairs.

Highlights

• Dynamic Benchmarking: Moves beyond static tests to environments that evolve during the task.
• Gaia2 Suite: A comprehensive evaluation set of 800 scenarios across multiple domains.
• Multilingual Support: The Omnilingual-Gaia2 extension allows for agent evaluation in 10 different languages.
• Interactive GUI: A web-based interface for real-time agent monitoring and DAG visualization of scenario execution.
• Broad Model Support: Integration with LiteLLM to support various AI model providers and local deployments.
