Amy Thomson and Vlad Savov of Bloomberg report that Elon Musk’s xAI launched Grok-3, claiming it outperforms rivals like GPT-4 in key benchmarks. The model features DeepSearch and a planned voice-based chatbot. However, experts note some inaccuracies and limitations remain. They write:
Elon Musk’s artificial intelligence startup xAI debuted its updated Grok-3 model, showcasing a version of the chatbot technology to challenge OpenAI days after the billionaire’s unsolicited cash bid to buy the company was rejected.
Across math, science and coding benchmarks, Grok-3 beats OpenAI’s GPT-4o, Alphabet Inc.’s Google Gemini, DeepSeek’s V3 model and Anthropic’s Claude, xAI said via a live stream on Monday. Grok-3 has “more than 10 times” the compute power of its predecessor and completed pre-training in early January, Musk said in a presentation alongside three xAI engineers.
Musk’s performance claims, which have not been independently verified, ramp up an increasingly bitter rivalry between his startup and OpenAI. He launched xAI in 2023 as an alternative to the ChatGPT maker, which he’s publicly criticized for its plans to restructure as a for-profit business. […]
Grok-3 is available Premium+ subscribers on X, a service that costs $22 a month. That compares to $200 a month for full access to OpenAI’s GPT-4o. xAI is starting a new subscription called SuperGrok for the bot’s mobile app and Grok.com website, and plans to open-source preceding versions of Grok models as soon as the latest one is fully mature. Musk said he expects that transition to be complete for Grok-3 in a few months. […]
But rival technologies are emerging that could challenge this model and make it easier for new competitors to emerge. Last month, Chinese AI company DeepSeek released a new open-source AI model, called R1, that matched or beat leading US competitors on a range of industry benchmarks. The company said it built the model for a fraction of the cost of its US counterparts.
