Elon Musk’s xAI has made an older version of its AI model Grok – specifically, the model weights used to shape Grok 2.5 – available on the open source platform Hugging Face. “The @AI Grok 2.5 model, which was our best model last year, is now open source,” Musk wrote on X. xAI’s CEO Elon Musk, posed on X that the company made the older Grok 2.5 model available to the public and will do the same with the upcoming Grok 3. Making Grok open source allows independent developers to potentially improve on the AI model, but xAI is still trying to move past an extremely alarming episode of Grok providing antisemitic responses and referencing itself as “MechaHitler.”The Decoder reported: xAI has released Grok 2 as an open model, including the weights. Elon Musk announced on X that Grok 2.5, xAI’s top model for 2024, is now open source.
