Openai will deploy its first open weight model for years

OPENAI is preparing to deploy its first open language model with advanced reasoning capacities since the publication of GPT-2 in 2019, the CEO SAM Altman announced on Monday.

“We have been thinking about it for a long time, but other priorities have priority,” said Altman in an article on X. “Now, it’s important to do.”

“We still have decisions to make, so we organize developer events to collect comments and play later with the first prototypes,” he added.

OPENAI did not immediately respond to a request for comments and more details.

Open weight AI models offer common ground between open-source and owner systems, only sharing the pre-formulated parameters of a neural network while keeping critical development details under Wraps. This means that developers can use the model for inference and fine adjustment, but they will not have access to the training code, an original data set or details on the architecture and methodology of the model.

In February, during an Ama Reddit session, Altman said that Optai had been “on the wrong side of history” concerning open source and noted that even if everyone in Openai does not share this perspective, internal discussions are underway. The company has generally favored a proprietary approach to a closed source development in the past.

In the same Reddit session, Kevin Weil, director of OPENAI products, also said that Optaai was considering older models of Oer-Opt which are no longer peak.

OPENAI previously said that Deepseek, a Chinese AI startup that quickly attracted attention with its AI model, R1, has poorly extended its technology thanks to a process known as “distillation”, where a smaller AI model learns from a greater. Unlike OpenAi models, Deepseek is entirely open-source and shows his full chain of thought.

Openai recently published GPT-4.5, known as “Orion”, February 27 and plans to launch GPT-5 in May. The AI ​​giant is also involved in the Stargate project, an initiative of $ 500 billion to build data centers announced by President Donald Trump.

The company announced on Monday that it had closed the largest private technological financing cycle ever recorded, including $ 30 billion in softbank and $ 10 billion from other investors, assessing the company to $ 300 billion with new capital.
