Waiting for OpenAI’s open source model? Be prepared to wait, as a report says that OpenAI delays its open source model indefinitely.

According to Silicon UK in an article titled (wait for it!) OpenAI Delays Open Source Model Indefinitely, written by Matthew Broersma and available here, OpenAI has indefinitely delayed the release of an open-source model for “safety testing”, as the company struggles to address a wave of open-source competition initiated by China’s DeepSeek earlier this year.

The release was scheduled for this week following an earlier delay a month ago, but OpenAI chief executive Sam Altman said the company wanted to “review high-risk areas”.

“We need time to run additional safety tests and review high-risk areas,” Altman said on social media, adding that the company was “not yet sure” how long this would take.

Aidan Clark, OpenAI’s vice president of research who is leading the open model team, said on social media that the team needed “more time” to attain the high standards it’s aiming for.

“Our bar for an open-source model is high and we think we need some more time to make sure we’re releasing a model we’re proud of along every axis,” Clark wrote.

Unlike OpenAI’s closed-source models, the open-source offering would be available for modification by users, who could run it on local hardware.

The model is expected to have similar reasoning capabilities to OpenAI’s o-series models and OpenAI is reportedly aiming for it to top other open-source models on performance and capabilities.

Altman began speaking about the possibility of releasing an open model soon after DeepSeek made headlines with its low-cost, high-performance open-source models in January.

In April he said the company would release its first open-weight model since GPT-2 in the coming months.

Open-weight models provide the ability to customize the weights, or relationships among the billions of parameters that are set during the model’s training, providing more visibility and control than closed systems.

“Once weights are out, they can’t be pulled back. This is new for us and we want to get it right”, said Altman.

Apparently, the “weighting”, as well as the “waiting”, is the hardest part! That’s heavy! 😉

So, what do you think? Are you surprised that there’s a report that OpenAI delays its open source model indefinitely? Or are you surprised they promised one in the first place? Please share any comments you might have or if you’d like to know more about a particular topic.
