Family parameters & versions

0 versions have verified published parameter counts; 13 have no usable value yet. Parameter count is not a performance ranking.

Parameter counts for this group have not yet been verified, so no numeric bars are shown. Check the uses, modalities, access options and version records below.

Version specifications by release date

Versions and size variants within the same family are shown separately. Each point needs both a specification reference and a release date. Points are not joined, and larger parameters or context do not imply better results.

Metric to compare

Unit: Token. Of 13 eligible versions, 13 have plotted values. 0 lack a value and 0 lack a release date; these gaps can overlap. Missing values are not zero.
