For the primary time since GPT-2 dropped over 5 years in the past, OpenAI is releasing not one, however two open-weight AI reasoning fashions — and so they’re out there to obtain at no cost proper now on Hugging Face.
Billed as “state-of-the-art,” the brand new OpenAI open-weight fashions had been introduced Tuesday in an organization weblog submit. OpenAI says they “outperform equally sized open fashions on reasoning, excel at device use, and are optimized for environment friendly deployment on shopper {hardware}.”

What does open-weight imply?
This launch is a nod to OpenAI’s early roots, when the corporate was extra publicly dedicated to open-sourcing its fashions (therefore the corporate’s identify). Whereas these aren’t “absolutely open supply” within the strictest sense — the coaching knowledge isn’t included — they’re open weight, that means the code and mannequin parameters can be found for anybody to make use of, tweak, and construct upon.

And no, fashions like Meta’s LLaMA aren’t really open supply both — at the very least not by the requirements of the open-source neighborhood, which requires entry to coaching knowledge as a baseline.
For the reason that launch of GPT-2, OpenAI has steadily shifted towards a extra closed and proprietary method to its LLM improvement — till now. The latest launch of open-weight fashions marks a notable change in path, and it’s not occurring in a vacuum.
With China’s DeepSeek AI and different labs within the nation gaining traction and reaching spectacular scores on benchmark assessments, the stress has been mounting for US tech corporations to remain aggressive within the international AI race. Actually, simply final month, the Trump administration urged American AI builders to open supply extra of their know-how in an effort to advertise innovation aligned with “American values” and keep a strategic edge.
Whatever the motivations behind it, this transfer represents a big step ahead, not only for OpenAI however for the broader open AI ecosystem.
