For research and development (R&D) organizations, the promise of agentic AI is not a better one-time answer. It is a new way to explore complex scientific and engineering problems: pursuing multiple hypotheses, validating them against evidence, learning from what does not work, and adapting their approach as new information becomes available.

This unique nature of the agentic discovery process has been a core area of research for Microsoft, and a design principle for Microsoft Discovery, our platform for organizations embracing Frontier R&D.

Measuring adaptive AI for scientific discovery

A new benchmark result shows how that opportunity is becoming real. On Agent’s Last Exam, a demanding evaluation of long-running, tool-using professional tasks, Microsoft Discovery Engine with CLIO (Cognitive Loop via In-Situ Optimization) achieved higher scores than the other agentic harnesses evaluated across three scientific domains: 61.6% in health and medicine, 75.2% in physical sciences, and 64.6% in life sciences.

This result builds on Microsoft’s core research into what makes agentic discovery distinctive. CLIO enables independent reasoning paths to explore a problem, compare and share learning, and resolve the strongest trajectory into a single evidence-backed result. The system can determine when to keep exploring, change strategy, use a different model, or bring a domain expert into the loop.

The CLIO benchmark blog post describes this adaptive reasoning approach in depth. More broadly, this core innovation for scientific discovery, powered by agentic AI, is available to R&D organizations in every industry and the scientific community with Microsoft Discovery not only as a research breakthrough, but as a foundation for real R&D work.

Why scientific discovery requires adaptive reasoning

Many of the hardest scientific and engineering challenges do not have a clearly defined workflow or a known answer. A researcher may need to navigate incomplete evidence, competing objectives, specialized tools, and changing constraints. A materials team may be balancing performance, safety, cost, and manufacturability. A life sciences team may need to connect literature, proprietary data, models, and experimental evidence before deciding what to validate next. An engineering team may need to search a vast design space without sacrificing physical fidelity or traceability.

In these settings, a single model response is not enough. Practitioners need systems that can reason over time, preserve evidence, challenge assumptions, and work within the tools, data, governance, and review processes their experts already use. Just as importantly, they need to understand how a conclusion was reached and where human judgment should enter the process.

Microsoft Discovery was designed as an enterprise platform for agentic R&D, combining the scientific mindset of hypothesis, experimentation, and refinement with the engineering rigor of problem decomposition, structured execution, and reproducibility. CLIO strengthens that foundation with a more adaptive reasoning loop and a diverse model ecosystem, while allowing researchers to use a diverse model ecosystem and multiple reasoning paths.

From benchmarks to real-world impact

The greater opportunity extends beyond benchmark rankings into real research environments. Discovery Engine with CLIO has already supported work that discovered a novel organic redox flow battery. The same approach has potential across design simulation (like for silicon chips), formulation and process optimization (for example in manufacturing and CPG), materials and molecular discovery (which can drive sustainability and drug discovery), and lab automation, areas where organizations need to shorten research cycles, without sacrificing rigor or traceability.

Agentic discovery does not replace scientists and engineers. It expands what they can explore, helps them learn faster from evidence, and gives them a more systematic and transparent way to move from an idea toward an outcome that experts can evaluate and validate.

Realizing the enormous opportunity to redefine R&D requires a platform built for the tools, data, governance, and review processes researchers already use. Microsoft Discovery was designed with that need in mind: to bring agentic discovery to researchers and scientists in R&D organizations across every industry and throughout the scientific community.

We are still early in this journey, but this benchmark milestone demonstrates what becomes possible when AI is built for the way discovery actually happens: iteratively, collaboratively, and adaptively. I look forward to seeing what organizations, researchers, and partners discover next.
