OpenAI announced the postponement of its first open-source large model release, with CEO Sam Altman stating that more time is needed for safety testing and risk assessment. This new model, which has performance comparable to o3-mini, may be named 'Open Model,' but the extent of its openness remains unclear. Research Vice President Aidan Clark emphasized that the company maintains strict standards for open source, as the model cannot be recalled once released. Although the delay disappointed some users, OpenAI believes ensuring safety and taking a responsible approach is more important. This decision will shape the future of models.

OpenAI announced the postponement of the open-source large model release. CEO Sam Altman stated that more time is needed for safety testing. The model was originally scheduled to be released this week but is now delayed until next week to ensure its safety and reliability. Altman emphasized that once the model is released, it cannot be recalled and must be handled with caution. This is OpenAI's first attempt to release a downloadable self-running model, aimed at providing powerful tools for researchers and small businesses. Although the delay is disappointing, the community generally understands the importance of safety testing and believes it is crucial for the AI ecosystem.
