Confirmed model releases
How model releases are confirmed
The release record separates confirmed events from forecasts, keeps the precision supported by the source, and links every entry to the evidence used for its date.
The short version
Model Updates publishes confirmed releases only. Every event needs a usable date and an attributable source. Expected dates, cadence forecasts, and unsourced launch claims stay out of the confirmed record.
Confirmation rules
A release needs an attributable source
The record requires a dated provider announcement, release note, model repository, documentation page, or another attributable primary listing. A rumor or an undated mention is not enough.
The stored date follows the source
An exact day is used when the source provides one. If only a month can be supported, the record keeps month precision and the interface labels it as such.
Variants released together stay together
Models launched in the same announcement can share one release event. Their individual model pages remain separate when BenchLM has distinct benchmark records.
Confirmation is not a quality judgment
A confirmed release can be ranked, unranked, generally available, a preview, or open weight. The release record establishes that the launch happened; benchmark evidence establishes what is known about performance.
Availability and corrections
Announcement date and broad availability are not always the same event. The source-linked release date is preserved rather than silently replacing it with a later API or regional availability date.
When a source changes or a date is corrected, the underlying release metadata is updated and the generated hub, provider archive, month archive, and timeline change together.
Model Updates does not infer an expected launch date from release cadence. Radar can monitor confirmed changes and send alerts, but a monitoring alert is separate from the public historical record.
