OpenAI will release open-source weights for a language model for the first time since GPT-2 in 2019

ChainCatcher news, according to Cointelegraph, OpenAI founder Sam Altman stated that a "new open-source weight language model" with reasoning capabilities will be released in the coming months, but he first hopes to gather feedback on "how to maximize its utility." An open-source weight language model refers to a model that can be publicly used, downloaded, modified, or deployed. While it is not as open as a fully open-source model, it represents a significant shift compared to the completely closed GPT-3 and GPT-4.

OpenAI partially open-sourced the GPT-2 model in February 2019 and completed the full open-source release in November of the same year. On February 12 of this year, Sam Altman stated that the company plans to launch GPT-4.5 and GPT-5 in the coming weeks or months.
