Elon Musk said his artificial-intelligence startup xAI will make the Grok 2 chatbot openly available next week, fulfilling a pledge to publish the source code of earlier models once newer versions are launched. “It’s high time we open sourced Grok 2. Will make it happen next week,” Musk wrote on the social-media platform X. The move extends xAI’s policy of releasing prior iterations after upgrades—Grok 4 is already in limited deployment—and comes as rivals such as OpenAI experiment with so-called open-weight models that stop short of full open sourcing. Musk first promised a staggered open-source approach in October 2024 as part of his broader advocacy for transparency in AI development.
