What this registry has checked

Quarantine. We hold the publisher’s own published hash for these weights and have recorded it against this entry. We have not downloaded and hashed the weights ourselves, so the hash is the publisher’s claim, not our measurement.

Measured on real hardware

None of these runs are ours. Each figure is the reporter’s, linked to their own evidence, under their own trust label. The number shown is single-stream decode — one user, concurrency 1 — because aggregate throughput across many users is a different quantity and reads as far faster than anyone will see.

Measured by local.ai

Hardware	Build measured	Decode @ 8K	Memory @ 8K	Decode mode
NVIDIA DGX Spark 128GB	nvfp4	133 tok/s	111.1 GB	dspark
NVIDIA DGX Spark 128GB	nvfp4	121 tok/s	109.3 GB	spec:dspark:k=8

Measured by local.ai, not by us: 2 runs. Each names its engine pinned by image digest and the exact serve command, in the full record.

Registry record as of 2026-09-01. Identity, licence and parameter count are properties of a release and do not move; tier can, and the verify link above re-checks it against the live registry rather than this page.
