[xAI Launches Skills] According to Golden Finance, on May 19 (local time May 18), Elon Musk's AI company xAI announced the simultaneous launch of the "Skills" feature on web, iOS, and Android platforms. This feature endows the AI assistant Grok with persistent memory across conversations, marking Grok's evolution from a traditional single-interaction chatbot to a configurable, programmable automated workspace. As introduced, through the "Skills" feature, users only need to teach Grok the operation method for a specific task once, and Grok can permanently remember related personal preferences, formatting rules, or specific workflow steps in all subsequent independent conversations. This means that when starting a new conversation, users no longer need to repeatedly input tedious pre-prompts or background settings.
