Definition
Plain language
A benchmark of multi-step real-world tasks meant to test how well general AI assistants actually perform.
As stated in the literature
A benchmark of long-horizon assistant tasks requiring multi-step reasoning, tool use, and information aggregation, designed to evaluate general AI capability.
Also called: GAIA-2
Why it matters: It evaluates whether assistants can chain real tools and information sources, which is where most consumer-facing AI products actually break.
For example, a GAIA task might ask an assistant to find the author of a specific scientific paper, locate their current affiliation, and email a meeting request — all in one chain.
