After first saying that OpenAI might have been “on the flawed facet of historical past” on the subject of open sourcing its applied sciences, CEO Sam Altman has introduced that the bogus intelligence (AI) firm will launch its first “open weight” language mannequin since GPT-2 within the coming months. This comes as the corporate battles perceptions that it could be ceding territory to rivals corresponding to DeepSeek and Meta, who’ve launched some variations of open weight AI fashions.
“We’ve been eager about this for a very long time however different priorities took priority. now it feels necessary to do,” Altman mentioned in a publish on X. The mannequin can have “reasoning” capabilities alongside the strains of OpenAI’s o3-mini.
Open weight vs open supply AI mannequin
To make certain, Altman mentioned that OpenAI would launch an open weight mannequin, and never an open supply mannequin — the previous has much less transparency in comparison with the latter.
Open supply fashions present full transparency, sharing supply code, mannequin structure, coaching algorithms, and weights underneath a licence permitting free use, modification, and distribution. Ideally, coaching information is disclosed, however authorized constraints typically restrict this. In distinction, open weight fashions solely have the educated mannequin weights, not the supply code, coaching information, or full structure particulars. This restricts transparency and customisation, since customers can run the mannequin however not absolutely modify or retrain it.
Why OpenAI is altering tack
After years of specializing in closed supply know-how, the shift in technique at OpenAI was triggered by the emergence of China’s DeepSeek. The latter confirmed the world {that a} language mannequin, which was open sourced, could possibly be made at a fraction of the associated fee that it took a few of its rivals to develop a mannequin. Meta has additionally discovered success by its open weight mannequin, Llama, which has hit greater than a billion downloads — although builders have complained that its mannequin’s licence phrases could possibly be commercially restrictive.
OpenAI at present provides its AI fashions by a chatbot and the cloud, in contrast to its rivals, whose fashions will be downloaded and modified by folks.
In a current Reddit Q&A, OpenAI CEO Sam Altman mentioned that the corporate has been on the flawed facet of historical past on the subject of open sourcing its applied sciences. “[I personally think we need to] determine a distinct open supply technique,” Altman mentioned. “Not everybody at OpenAI shares this view, and it’s additionally not our present highest precedence… We are going to produce higher fashions, however we’ll preserve much less of a lead than we did in earlier years.”

In accordance with a suggestions kind printed by OpenAI on its web site, the corporate was inviting “builders, researchers, and [members of] the broader group” and included questions like, “What would you wish to see in an open weight mannequin from OpenAI?” and “What open fashions have you ever used up to now?”
When will OpenAI launch its open weight AI mannequin?
In his X publish, Altman mentioned that earlier than launch, OpenAI will consider this mannequin based on its preparedness framework, “like we’d for some other mannequin. And we’ll do further work provided that we all know this mannequin will likely be modified post-release”.
The corporate nonetheless has “some choices to make” and is internet hosting developer occasions to collect suggestions and later play with early prototypes. “We’ll begin in (San Francisco) in a few weeks adopted by classes in Europe and APAC,” he added.
Steven Heidel, a member of the technical employees at OpenAI, reposted Altman’s announcement on X and added, “We’re releasing a mannequin this yr you can run by yourself {hardware}.”
