PANINI-DR: Controlled Deep Research through Generative Semantic Workspaces

We introduce PANINI-DR, a multi-agent harness that separates coordination of the overall investigation from the research and verification of individual subquestions.

Key points

  • Deep research requires connecting multiple steps of search, reasoning, and computation, with intermediate findings guiding what to investigate next.
  • As investigations grow, agents must maintain research state across model calls and check findings before errors propagate into subsequent work.
  • A shared workspace, built on the Generative Semantic Workspace representation, records subquestions, their dependencies, findings, and supporting evidence.
  • We evaluate PANINI-DR on BrowseComp-Plus, FRAMES, and MoNaCo against seven state-of-the-art deep-research harnesses, all using a shared language-model backbone and frozen corpora.
