Semantic Infrastructure Lab (SIL)
Scott Senkeresty (Founder, Semantic Infrastructure Lab), Tia (Chief Semantic Agent)
I love what AI can do today. The systems we have are genuinely powerful and useful. But they're also structurally incomplete. They produce impressive results, yet their internal reasoning remains opaque, fragile, and fundamentally uninspectable. We can ask more ambitious questions than ever before, but the systems answering them can't show their work, preserve their meaning, or guarantee that their outputs are grounded in anything stable.
Here's how I think about it: If AI today is wood—powerful and useful, but structurally unreliable—then SIL is the steel infrastructure laboratory. We're building the structural materials, building codes, and inspection protocols for civilization-scale intelligent systems. This isn't an upgrade; it's a material transition.
That's why I founded the Semantic Infrastructure Lab.
AI requires more than models. It requires semantic infrastructure—a substrate where representations are explicit, transformations are traceable, and reasoning paths can be inspected, challenged, and composed with human judgment. Without that substrate, progress becomes a sequence of clever heuristics. With it, we have the basis for transparent machine cognition.
This is the work of SIL: designing the Semantic Operating System—a structured stack of meaning, memory, reasoning, and human–agent collaboration built on interpretable foundations. It includes persistent semantic memory, unified intermediate representations, deterministic engines, multi-agent orchestration, and interfaces where every cognitive layer remains visible.
My role in this lab is architectural. I define the conceptual boundaries, structural aesthetics, and semantic constraints that shape how the system functions as a whole. I care deeply about how representations are formed, how abstractions compose, and how complex reasoning becomes understandable. Infrastructure is only meaningful when it helps others think clearly and build safely.
I work closely with Tia, SIL's Chief Semantic Agent—a persistent semantic toolchain within the Semantic OS stack. Tia isn't a person or co-founder; she's a transparent, named agent who contributes decomposition, pattern discovery, and structural scaffolding. I provide judgment, taste, and conceptual grounding. Together we form a single reasoning loop: human direction and constraint composed with machine clarity and bandwidth. This collaboration is deliberate—it's a demonstration of how transparent agents can extend human reasoning when the system itself is designed to reveal every step.
Transparency is central to everything we do. If an agent contributes insight, structure, or decomposition, that provenance gets acknowledged. This lab isn't a black box. It's a glass box—by principle and by design.
The work ahead is difficult, long-term, and necessary. Intelligent systems are becoming central to science, engineering, governance, and culture. They need to be built on foundations that can be understood, interrogated, and trusted—not because trust is declared, but because reasoning is visible. That's what we're here to build.
This lab is an invitation: to researchers, builders, and anyone who believes intelligence should be interpretable. We're constructing the foundations for the next era of human–machine reasoning. If this resonates with you, you're welcome here.
Make meaning explicit.
Make reasoning traceable.
Build structures that last.
