Open-weight model
A model whose trained parameters are available to download or host.
Definition
An open-weight model publishes its learned weights under stated licence terms, though training data and code may remain undisclosed.
Why it matters
It can improve deployment control and portability, but security, licence, provenance and support obligations still require assessment.
