Grok 2.0 and Grok 2 Mini, cutting-edge language models, are now in beta on the X platform. These models are outperforming competitors like Claude 3.5 Sonnet and GPT-4 Turbo on the LMSYS leaderboard. Grok is gaining attention for its lenient approach compared to rivals such as ChatGPT and Copilot. The models are trained by the world's most powerful AI cluster, with Elon Musk envisioning Grok as the most powerful AI by December. Users can now easily save images generated by Grok on both web and mobile platforms.
