Just as OpenAI launched GPT-5.2, xAI CEO Elon Musk recently made an important announcement about their own AI model, Grok. Released around the same time as GPT-5.1 during mid-November this year, Musk shared a surprising aspect of Grok 4.1 that also came as a surprise to LLM users and developers. In one of his latest posts on X, the Tesla chief executive seemed impressed with Grok 4.1’s efficiency when pitted against one of its biggest rivals in the AI market, GPT-5.2.
This new development has made quite a mark on social media, as many ponder over Grok 4.1’s potential as an agentic tool. Many netizens shared how impressed they were with the rapid developments made by the team behind Grok 4.1. However, some users wondered about xAI’s LLMs’ functionality regarding complex workflows and the potential for varied utility by employees themselves.
