HeteroIR is not a framework, not a classical IR, and not a compatibility layer. It is the substrate — the internal world where all computation can exist, evolve, and execute without being forced into classical assumptions. This page defines what the substrate can do.
Modern computation spans four fundamentally different worlds:
HeteroIR represents all of them as first-class citizens in one unified graph. No approximations. No classical shadows. No forced translation into tensor-centric abstractions — every architecture expresses itself natively.
HeteroIR provides a single semantic space capable of expressing:
This unification is not layered or emulated — it is intrinsic to the substrate. Logic gates, optical interference, spike trains, and quantum amplitudes coexist without semantic conflict.
A single HeteroIR graph can lower into multiple hardware families:
Lowering preserves the semantics declared in the graph. The substrate ensures that meaning survives the transition from representation to execution — the foundation of true heterogeneous compute.
Classical IRs assume static graphs. HeteroIR does not. Graphs in the substrate can:
This capability enables systems that are not merely reactive — they are alive within the substrate.
Computation is no longer bound to a single physical model. HeteroIR coordinates:
All within one internal world — the first substrate capable of expressing multi-physics computation coherently.
Because architecture and algorithm share the same representational world, they can co-evolve. HeteroIR enables:
This collapses the historical divide between hardware and software.
HeteroIR provides canonical structure for:
These optimizations operate at the substrate level, not the framework level, ensuring consistency across all architectures. The substrate becomes the single source of truth for computation.
HeteroIR is the first system capable of expressing, optimizing, and executing computation across all paradigms — classical, photonic, neuromorphic, quantum — within one unified substrate.
This is the foundation for the next era of intelligence.
