GAIA Benchmark

GAIA, introduced by Mialon et al. in 2023, stands for 'General AI Assistants'. It contains 466 questions across three difficulty levels that are simple for humans but require an AI agent to orchestrate tools — web search, code execution, image and audio understanding, file parsing — over multiple steps. The benchmark emphasises real-world grounding: every question has a single verifiable answer, but getting there typically needs 5-50 tool calls. GAIA has become a leaderboard standard for agent frameworks from Hugging Face, OpenAI, and Manus to academic prototypes.

Frequently asked questions

What is the GAIA benchmark?

GAIA (General AI Assistants) is a 466-question benchmark for evaluating AI agents on real-world tasks. Each question has a verifiable single answer but requires multi-step tool use — web browsing, code, file parsing, multimodal understanding — to solve.

What's the difficulty structure?

GAIA has three levels. Level 1: humans solve ~93% with basic tool use in minutes. Level 2: longer tool chains, 8-10 steps. Level 3: complex, long-horizon, multi-modal reasoning. Humans still score ~92% overall; even strong agents drop sharply on Level 3.

Why does GAIA matter?

It exposes what benchmarks like MMLU miss: the gap between 'knows an answer' and 'can get the answer by operating the web and tools reliably'. Agent frameworks (LangGraph, OpenHands, Manus) are often first reported on GAIA to show real utility.

What are common failure modes on GAIA?

Getting lost in long tool chains, hallucinating intermediate results instead of actually using tools, mishandling file attachments, misreading webpages (especially tables and PDFs), and exceeding step or token budgets.
