Before it
Large models were built inside single companies and released, if at all, on their terms.
The problem
No model of that scale had been built by an open scientific collaboration, and none covered many languages well.
What it introduced
A 176B multilingual model trained in public by a thousand researchers on a national supercomputer, released with a responsible-use licence.
Why it matters
It proved a large model could be built as open science, and put multilingual coverage on the agenda.
What modern models inherit
Open collaborative training, and the idea of use-restricted rather than fully free licences.
What came next
The RAIL licence influenced later custom licences; the collaboration model informed open data efforts.
