AI-Scientist-v2 vs Auto-claude-code-research-in-sleep

Auto-claude-code-research-in-sleep is much bigger: 15.7k stars against 7.1k. Over the days we have tracked them AI-Scientist-v2 moved +2.7% and Auto-claude-code-research-in-sleep +14.6%, so Auto-claude-code-research-in-sleep is growing faster right now.

Auto-claude-code-research-in-sleep leads on noise control and customization. AI-Scientist-v2 does not take any axis by a clear margin.

Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.

Where they stand today

End-to-end autonomous scientific discovery: it uses progressive agentic tree search to ideate, run experiments, analyze results, and draft papers without human-authored templates.
