Meta AI has introduced Agents Research Environments (ARE), a modular simulation stack for creating and running agent tasks, and Gaia2, a follow-up benchmark to GAIA that evaluates agents in dynamic, write-enabled settings. ARE provides abstractions for apps, environments, events, notifications, and scenarios; Gaia2 runs on top of ARE and focuses on capabilities beyond search-and-execute. Why move from sequential to asynchronous interaction?

Meta AI has introduced Agents Research Environments (ARE), a modular simulation stack for creating and running agent tasks, and Gaia2, a follow-up benchmark to GAIA that evaluates agents in dynamic, write-enabled settings. ARE provides abstractions for apps, environments, events, notifications, and scenarios; Gaia2 runs on top of ARE and focuses on capabilities beyond search-and-execute. Why move from sequential to asynchronous interaction?

We introduce Gaia2, a benchmark for evaluating large language model agents in realistic, asynchronous environments. Unlike prior static or synchronous evaluations, Gaia2 introduces scenarios where environments evolve independently of agent actions, requiring agents to operate under temporal constraints, adapt to noisy and dynamic events, resolve ambiguity, and collaborate with other agents. Each scenario is paired with a write-action verifier, enabling fine-grained, action-level evaluation and making Gaia2 directly usable for reinforcement learning from verifiable rewards. Our evaluation of state-of-the-art proprietary and open-source models shows that no model dominates across capabilities: GPT-5 (high) reaches the strongest overall score of 42% pass@1 but fails on time-sensitive tasks, Claude-4 Sonnet trades accuracy and speed for cost, Kimi-K2 leads among open-source models with 21% pass@1. These results highlight fundamental trade-offs between reasoning, efficiency, robustness, and expose challenges in closing the "sim2real" gap. Gaia2 is built on a consumer environment with the open-source Agents Research Environments platform and designed to be easy to extend. By releasing Gaia2 alongside the foundational ARE framework, we aim to provide the community with a flexible infrastructure for developing, benchmarking, and training the next generation of practical agent systems.

Introduction: A New Era for AI Agents AI agents have long been envisioned as smart assistants capable of handling complex tasks effortlessly. Ideally, they would follow instructions, adapt to unexpected situations, and execute multi-step plans without errors or hallucinations. Yet, testing such abilities has proven challenging—traditional evaluation environments are limited, overly task-specific, and fail to capture the unpredictability of real-world scenarios.
