OpenAI just released two generative AI models: gpt-oss-120b and gpt-oss-20b. While neither of them is the highly anticipated GPT-5, they mark a significant step forward for OpenAI.
Both gpt-oss-120b and gpt-oss-20b are open-weight models, meaning the parameters used to train the models are available to the public. OpenAI has not released an open-weight model since GPT-2 in 2019.
