Local-first AI infrastructure

Compile intelligence
into something you can inspect.

Prism Engine turns model weights into compact, measurable compute images and runs them close to the hardware. Every placement, artifact, and outcome has a trail.

behind the answer.

Compilation is not a loading spinner. Prism exposes the path from source weights to an executable artifact, then lets researchers inspect the decisions that shaped it.

02 / Architecture

One artifact.
Explicit planes.

Prism keeps authority, execution, and projection separate. Hardware-specific work can move quickly without becoming an untraceable source of truth.

01
AUTHORITY PLANE

Validated state

Commands, lifecycle, leases, receipts, replay.

02
EXECUTION PLANE

Native work

Metal, CPU, Core ML, memory, kernels.

03
EVIDENCE PLANE

What happened

Digests, metrics, receipts, verification.

04
PROJECTION PLANE

Useful views

Dashboards, Compiler Lab, analytics, operator surfaces.

03 / Product surfaces

Designed for
two kinds of attention.

Researchers need the knobs and evidence. Everyone else needs a clear answer to “what is happening?” Prism gives both views without hiding the boundary between them.

04 / Current reality

Ambitious claims.
Precise labels.

Prism is pre-1.0 systems software. The strongest path today is native Apple Silicon execution; every other claim is scoped to its actual build and evidence.
