 **A quick note:** We’ll benchmark our results on the same GAIA challenge but keep in mind that this is a work in progress. DeepResearch is a massive achievement and its open reproduction will take time. In particular, full parity will require improved browser use and interaction like OpenAI Operator is providing, i.e. beyond the current text-only web interaction we explore in this first step.
