Andrej Karpathy shared his early impressions of Grok 3, xAI's latest large language model. He found it remarkably fast, even surpassing GPT-4 in speed, and capable of complex reasoning, code generation, and even humor. Karpathy highlighted Grok's unique "personality" derived from its training on real-time information, including news and current events, giving it a distinct, up-to-the-minute awareness. This real-time data ingestion also allows Grok to make current event references and exhibit a kind of ongoing curiosity about the world. He was particularly impressed by its ability to rapidly adapt and learn within a conversation, showcasing a significant advancement in interactive learning capabilities.
xAI announced the launch of Grok 3, their new AI model. This version boasts significant improvements in reasoning and coding abilities, along with a more humorous and engaging personality. Grok 3 is currently being tested internally and will be progressively rolled out to X Premium+ subscribers. The accompanying video demonstrates Grok answering questions with witty responses, showcasing its access to real-time information through the X platform.
HN commenters are generally skeptical of Grok's capabilities, questioning the demo's veracity and expressing concerns about potential biases and hallucinations. Some suggest the showcased interactions are cherry-picked or pre-programmed, highlighting the lack of access to the underlying data and methodology. Others point to the inherent difficulty of humor and sarcasm detection, speculating that Grok might be relying on simple pattern matching rather than true understanding. Several users draw parallels to previous overhyped AI demos, while a few express cautious optimism, acknowledging the potential while remaining critical of the current presentation. The limited scope of the demo and the lack of transparency are recurring themes in the criticisms.
