Portrait of Jackie Jiaqi Yin

ML Scientist at OpenAI

Hey, I'm Jackie
I build revenue intelligence and grounded AI systems

I’m an ML Scientist at OpenAI working on B2B revenue forecasting and strategic modeling to better understand business demand, inform growth decisions, and turn noisy signals into decision-ready insight. Alongside that work, I stay deeply invested in AI systems design, evaluation, retrieval, and open-source tools that help people learn faster, read research more effectively, and work more intelligently with data.

Previously, I worked across forecasting, experimentation, recommendation systems, and AI product development at Microsoft, including context engineering and evaluation for Copilot Notebooks. I also collaborate across health AI and aging-related work, and build self-driven open-source tools such as codex-skills, ArxivSummary, and schema-lineage tooling.

More about my background

What I Work On

Building impact across work and AI side projects.

My core role is business-critical machine learning. My side work stays broad, self-driven, and deeply practical.

Work

Revenue Forecasting & Strategic Modeling

I build B2B revenue forecasting and strategic models that help surface demand patterns, sharpen planning, and connect machine learning work to concrete growth decisions.

AI Product

Applied AI Systems & Evaluation

I’ve worked end to end on AI product development, including context engineering, prompt design, tool usage, and evaluation for grounded systems such as Microsoft Copilot Notebooks.

Self-Driven

Open Source, Research Tools, and Data Workflows

I build open-source AI tooling and research-facing systems that help people synthesize papers, mine data more effectively, and turn technical curiosity into useful software.

Interested in AI products, modeling, or research tooling?

I’m especially interested in work that connects technical rigor to real outcomes, whether that means better revenue insight, stronger AI product behavior, or more useful open-source systems.
