BWhat changed
Released a family of 125M–175B-parameter decoder-only language models with training logs and evaluation, expanding access to large-scale model research.
Scientific scope
Released a family of 125M–175B-parameter decoder-only language models with training logs and evaluation, expanding access to large-scale model research. Scope limitation: This is the 2022 OPT paper and release, not an invention of decoder-only transformers or a claim of unrestricted access to every model.
Evidence
The retained primary-source abstract, bibliographic record and stated review scope support this provisional assessment. No independent experimental replication by WRS is claimed. This is the 2022 OPT paper and release, not an invention of decoder-only transformers or a claim of unrestricted access to every model.
