Sam Altman Says OpenAI Will Release an ‘Open Weight’ AI Model This Summer

“We are excited to release a powerful new open-weight language model with reasoning in the coming months,” Altman wrote on X.

Altman said in the post that the company has been thinking about releasing an open weight model for some time, adding “now it feels important to do.”

The move is partly a response to the runaway success of the R1 model from Chinese company DeepSeek, as well as the popularity of Meta’s Llama models.

OpenAI may also feel the need to show that it can train the new model more cheaply, since DeepSeek’s model was purportedly trained at a fraction of the cost of most large AI models.
