Findings
Scanned 2026-08-27 · published from a community scan.
info Embedding-norm glitch scan clean
No undertrained tokens found: every non-special token's embedding norm is above 0.3× the vocabulary median (1.119). The glitch-token data-corruption class has no candidate surface in this model.
info Weights consistent with claimed parent google/gemma-4-31B
Mean cosine similarity of 64 sampled token-embedding rows against google/gemma-4-31B is 0.867 — the weights plausibly descend from the declared base (relation: unspecified).
Remediation guidance addresses the documented findings only. It is evidence-driven repair, not a safety certification of the model.
Check every checkpoint before it ships
Use the web app, API, CLI, or CI gate to scan candidate checkpoints and catch model drift before deployment. Public-model scans publish to the open database; paid plans add the volume needed for continuous checks.
