Philosophy: An AI co-scientist is an agent that collaborates with researchers across the entire scientific method — generating hypotheses, designing experiments, writing and executing code, and analyzing results. The goal is not to replace scientists but to give every curious person the tools to do rigorous research.
The operating system metaphor: AI-native research infrastructure replaces the fragmented stack of notebooks, cluster schedulers, and ad-hoc scripts with a unified substrate where hypothesis generation, experiment execution, result analysis, and writeup share one memory and one state. Think of it as an operating system whose processes are research tasks and whose kernel is an orchestrator of AI co-scientists.
Three pillars:
Paper: Kon*, P. T. J. & Liu*, J. et al. (2025). "Curie: Toward Rigorous and Automated Scientific Experimentation with AI Agents." arXiv:2502.16069. (*Co-first authors)
What it is: The first AI-agent framework designed for automated and rigorous scientific experimentation. Automates the full lifecycle: hypothesis formulation → experiment design → implementation → execution → result analysis → finding reflection.
Key differentiator — Rigor: Curie is the only system that builds verification into every stage. Most agents focus on "can the agent run the code?" Curie asks "can the agent do valid science?"
Architecture highlights:
How to talk about it: "Curie was the first framework to treat rigor as a first-class concern in automated experimentation. Most existing agents are 'code generators that happen to run experiments' — Curie is an 'experiment agent that happens to write code.' The distinction matters because science without rigor isn't science."

Paper: Kon*, P. T. J. & Liu*, J. et al. (2025). "EXP-Bench: Can AI Conduct AI Research Experiments?" arXiv:2505.24785. Published at ICLR 2026. (*Co-first authors, built with Matei Zaharia's group at Berkeley)
What it is: A benchmark evaluating whether AI agents can conduct AI research experiments end-to-end — from hypothesis to conclusion.
Scale: 461 experiments from NeurIPS/ICLR papers → 12,000+ gradable subtasks.
Construction: Semi-automated pipeline that extracts experiment tasks from published papers + codebases, using ground-truth conditioning for task reconstruction, interleaved with human validation.
The headline result: OpenHands + Claude Sonnet 3.7 achieves ~20–35% on individual steps but 0.5% on full experiment completion. This is the single most important data point in the field right now.
What the 0.5% means: Current AI agents can handle individual pieces of research (writing code, setting up experiments, analyzing data) but cannot maintain coherent plans across the full multi-step research lifecycle. The compounding of errors across steps is the bottleneck — not any single capability.
Failure mode analysis:
Scope limitation: Currently covers only AI/ML papers. Does not yet address physical science or true scientific invention.
How to talk about it: "EXP-Bench showed that even the best agents today complete less than 1% of full research experiments. The interesting finding isn't that they fail — it's where they fail. They can write code, they can set up experiments, they can analyze results — but they can't do all three in sequence with a coherent plan. That's a planning and memory problem, not a capability problem."
For full evaluation details: read → reference/exp-bench.md
What it is: A comprehensive open-source library of 83 modular skills across 20 categories that enable AI agents (and humans) to conduct AI research experiments — preparing datasets, executing training pipelines, deploying models, analyzing results.
Why it matters: Modern AI research requires mastering dozens of specialized tools and frameworks. Researchers spend more time debugging infrastructure than testing hypotheses. The Skills Library packages this expertise into modular, invocable knowledge units that any coding agent can use.
20 categories: Model Architecture (5), Fine-Tuning (4), Post-Training (8), Distributed Training (6), Optimization (6), Inference (4), Tokenization (2), Data Processing (2), Evaluation (3), Safety & Alignment (4), Agents (4), RAG (5), Multimodal (7), Prompt Engineering (4), MLOps (3), Observability (2), Infrastructure (3), Mechanistic Interpretability (4), Emerging Techniques (6), ML Paper Writing (1)
Installation: npx @orchestra-research/ai-research-skills — works with Claude Code, OpenCode, Cursor, Codex, Gemini CLI, Qwen Code.

Relationship to Curie/EXP-Bench: The Skills Library provides the engineering capability layer — the practical know-how to execute experiments. Curie provides the experiment orchestration layer — the methodology and verification. EXP-Bench provides the evaluation layer — measuring whether it all works together.
How to talk about it: "Think of it as the difference between having a brilliant research idea and knowing how to actually implement it. Most AI agents today are good at the former but terrible at the latter. The Skills Library bridges that gap by packaging expert-level knowledge of frameworks like Megatron-LM, vLLM, TRL, DeepSpeed — the actual tools researchers use — into a format agents can consume."
What it is: An AI-for-science platform for "vibe research" — helping researchers move from question to publication with literature review, coding, experimentation, analysis, and writing in one place.
Website: orchestra-research.com
The vision: Replace the fragmented stack of notebooks, cluster schedulers, and ad-hoc scripts with a unified substrate. An operating system whose processes are research tasks and whose kernel is an orchestrator of AI co-scientists.
What "vibe research" means: Research should feel like a conversation with a knowledgeable collaborator, not like a series of disconnected tools. The researcher proposes ideas; Orchestra handles the infrastructure — scheduling experiments, managing dependencies, tracking results, generating reports.
Relationship to Jiachen's other work:
How to talk about it: "We're not building a better notebook or a better cluster scheduler. We're building a new kind of substrate for research itself. The key insight is that the current tool stack fragments the research process — your ideas live in one place, your code in another, your results in a third, your writeup in a fourth. Orchestra unifies all of that so that an AI co-scientist can maintain context across the entire research lifecycle."
Jiachen's research trajectory connects two worlds:
ML Systems Foundation (UMich PhD, Mosharaf Chowdhury):
AI for Science (current focus):
The bridge insight: "To build AI agents that can do research, you need to first understand the systems that make AI research possible — efficient serving, distributed training, energy-aware infrastructure. My ML systems work taught me what the infrastructure layer needs to look like. The AI for Science work is building on top of that foundation."
On the overall vision:
"I'm building AI-native research infrastructure so that everyone can be a scientist. Not a replacement for scientists — a democratization of the ability to do rigorous research. The current tool stack forces researchers to be plumbers, not scientists."
On Curie's key innovation:
"Curie was the first framework to treat rigor as a first-class concern. Most agents ask 'can the agent run the code?' We ask 'can the agent do valid science?' The distinction matters because science without rigor isn't science — it's just scripting."
On EXP-Bench's 0.5% result:
"The headline number is sobering, but the where of failure is more interesting than the how much. Agents can write code, set up experiments, analyze data — but they can't do all three in sequence. It's a planning problem, not a capability problem. That's actually encouraging because it tells us where to focus."
On the Skills Library:
"Modern AI research requires mastering dozens of specialized frameworks. Researchers spend more time debugging infrastructure than testing hypotheses. The Skills Library packages that expertise into modular units that any coding agent can consume. It's the engineering knowledge layer that makes AI co-scientists practical."
On Orchestra / Vibe Research:
"We're building a new substrate for research itself. Think of it as an operating system whose processes are research tasks and whose kernel is an orchestrator of AI co-scientists. The key insight is that the current tool stack fragments the research process."
On Sci-Reasoning:
"If we want AI agents to do innovative research, we need to understand what makes research innovative. Sci-Reasoning captures the intellectual synthesis patterns behind AI breakthroughs — 15 thinking patterns that drive innovation. It's the map for where AI agents need to go."
On the relationship between ML systems and AI for Science:
"To build AI agents that can do research, you first need to understand the systems that make AI research possible. My ML systems work — LLM serving, training infrastructure, energy benchmarks — taught me what the infrastructure layer needs. The AI for Science work builds on top of that."
Q: "Isn't this just AutoGPT for science?"
"No. AutoGPT is a general-purpose agent framework with no domain expertise. Curie has built-in verification modules that enforce scientific methodology. The Skills Library provides 83 domain-specific skills. It's the difference between a Swiss Army knife and a surgeon's toolkit."
Q: "How is Curie different from The AI Scientist?"
"The AI Scientist focuses on generating research papers — the end product. Curie focuses on the experimentation process itself — rigor, reproducibility, methodological soundness. We care about whether the science is right, not just whether a paper exists."
Q: "Will AI replace scientists?"
"No. The goal is democratization, not replacement. AI co-scientists let more people do rigorous research by handling the infrastructure burden. The best research will always be human-AI collaboration — humans bring curiosity and judgment, AI brings scale and rigor."
Q: "What's the most important result in this space?"
"EXP-Bench's 0.5% end-to-end success rate. It tells us exactly how far we are from automating research and, crucially, why — the planning and memory bottleneck across multi-step experiments."
Q: "What's next for this research?"
"Three things: (1) expanding EXP-Bench beyond AI papers to physical sciences, (2) improving agent planning through better memory architectures, and (3) building Orchestra into a platform that researchers actually use day-to-day."
