Before the release, OpenAI plans to gather feedback to ensure its utility. This marks the first “open-weight” model since GPT-2 in 2019.
Looking Ahead
Altman shared that developer events for the GPT-2 model will start in San Francisco, followed by sessions in Europe and the Asia-Pacific region. He expressed excitement over seeing how developers and organizations use the model, especially when running it privately.
An open-weight model allows public access for modification and deployment, unlike the fully closed GPT-3 and GPT-4 models. The announcement also comes as OpenAI plans to release GPT-4.5 and GPT-5 soon.
