Open Weight Models
OWM Change History

History that starts when observation starts.

Open Weight Models records material changes from 27 September 2026 forward. We do not fabricate an earlier timeline. The value compounds as model cards, licenses, checkpoints, runtimes and deployment facts change over time.

Methodology

What OWM watches

Legal & accessLicense, policies, gating and commercial-use implications.
Model identityModel-card claims, exact checkpoint, context and architecture changes.
DeploymentRuntimes, quantizations, hardware guidance and provider availability.
OWM evidenceNew reproduced tests, corrections and evidence-status changes.

Observed events

At launch, each model has a verified baseline. Additional entries should only be added when OWM actually observes a material change.
