WHAT DO THE LEVELS MEAN?

  • L0 · Reference — Reference Resources: Curated lists, awesome-repos, and initiatives that support AI-in-research workflows — starting points, not end-products.
  • L1 · Tool — LLM as Tool: AI tools that augment a single researcher task — literature search, writing, reviewing, figure generation, content transformation.
  • L2 · Analyst — LLM as Analyst: Research agents with stronger analysis, modeling, and experiment-execution abilities — they plan and reason across steps.
  • L3 · Scientist — LLM as Scientist: End-to-end autonomous research systems. AI-Scientist-style agents that frame hypotheses, run experiments, and write papers.
