GigaTIME Arrives in Microsoft Foundry: Transforming Pathology Images into Biological Insights

Microsoft Foundry has expanded its scientific AI capabilities with the addition of GigaTIME, a groundbreaking multimodal model that transforms routine pathology images into detailed biological insights. This development represents a significant advancement in healthcare AI, enabling researchers to extract complex tumor microenvironment data from standard hematoxylin and eosin (H&E) slides that are routinely collected across healthcare systems.

From Routine Slides to Deep Biological Understanding

Understanding tumor-immune interactions has become central to modern cancer research, but traditional methods like multiplex immunofluorescence, while powerful, are expensive and difficult to scale across large patient populations. GigaTIME addresses this fundamental challenge by translating widely available pathology slides into spatially resolved protein activation maps.

The model allows researchers to infer critical biological signals including immune activity, tumor growth patterns, and cellular interactions at unprecedented depth. Developed through collaboration between Microsoft Research, Providence, and the University of Washington, GigaTIME enables analysis across diverse cancer types, accelerating discovery and deepening our understanding of disease biology.

Real-World Applications Transforming Research Workflows

GigaTIME supports multiple research and evaluation workflows across scientific scenarios:

Population-Scale Analysis: Generate virtual multiplex immunofluorescence outputs from routine pathology slides, enabling large-scale analysis of tumor-immune interactions that would be prohibitively expensive using traditional methods.

Biomarker Discovery: Identify relationships between protein activation patterns and clinical attributes such as mutations, biomarkers, and disease characteristics, potentially uncovering new diagnostic or prognostic indicators.

Patient Stratification: Segment patient populations across cancer types and subtypes using spatial and combinatorial signals for research and hypothesis generation, enabling more precise cohort definitions.

Clinical Trial Retrospective Analysis: Apply GigaTIME to H&E archives from completed clinical trials to retrospectively characterize tumor microenvironment features associated with treatment outcomes, extracting new insights from existing trial data without additional tissue processing.

Tumor-Immune Interaction Analysis: Assess whether immune cells are infiltrating tumor regions or being excluded by analyzing spatial relationships between tumor and immune signals, providing crucial information about treatment resistance mechanisms.

Immune System Structure Characterization: Understand how immune cell populations are organized within tissue to evaluate coordination or fragmentation of immune response, which has implications for immunotherapy effectiveness.

Immune Checkpoint Context: Examine how immune activity may be locally regulated by analyzing overlap between immune markers and checkpoint signals, potentially identifying new therapeutic targets.

Tumor Proliferation Analysis: Identify actively growing tumor regions by combining proliferation signals with tumor localization, enabling more precise identification of aggressive disease.

Stromal and Vascular Context: Analyze how tissue architecture, such as vascular density and desmoplastic stroma, shapes immune cell access to tumor regions, helping characterize mechanisms of immune exclusion or infiltration.

Exploration Path: From Labs to Production

Microsoft Foundry provides a structured path for engaging with GigaTIME, starting with exploration and progressing to production deployment.

Foundry Labs: Early Exploration

Foundry Labs offers a lightweight environment for early exploration of emerging AI capabilities. For GigaTIME, this means developers and researchers can quickly understand how the model behaves before integrating it into production workflows.

Through curated experiences in Foundry Labs, users can:

• Run inference on pathology images
• Visualize spatial protein activation patterns
• Explore tumor and immune interactions in context

This guided exploration helps build intuition and evaluate how the model can be applied to specific use cases before committing to full deployment.

GitHub Examples: Advanced Customization

For advanced scenarios, Microsoft provides access to underlying notebooks and workflows via GitHub. These examples offer flexibility to customize pipelines, extend workflows, and integrate GigaTIME into broader research and application environments.

The combination of Foundry Labs for guided exploration and GitHub for advanced customization provides a complete path from initial experimentation to production deployment.

Discovery and Deployment in Foundry

GigaTIME is available in the Foundry model catalog alongside a growing set of domain-specific models across healthcare, geospatial intelligence, physical systems, and more.

For research workflows, GigaTIME can be deployed as an endpoint within Foundry to support:

• Biomarker discovery pipelines
• Patient stratification workflows
• Clinical research applications

Users can start with early exploration in Foundry Labs and transition to scalable deployment on the Foundry platform using tools and workflows designed for each stage, aligned with the model's intended use.

A New Class of Scientific AI

GigaTIME represents a broader shift toward AI systems designed to model real-world phenomena. These systems are characterized by:

• Multimodal capabilities: Processing and integrating different types of data
• Domain specificity: Deeply tied to specialized scientific data and use cases
