‘Broad access to these capable open-weights models created in the US helps expand democratic AI rails,’ OpenAI said.

OpenAI on Aug. 5 released two open-weight language models, the company’s first such release since GPT-2 in 2019.

Open-weight models make their training parameters, or weights, publicly available but tend not to provide access to the source code or datasets. Open-source models typically include access to the source code, weights, and methodologies.
