xAI公司发布了最新的AI模型Grok-3，其算力是前代产品的十倍以上。在早期测试中，Grok-3在推理能力上超越了OpenAI的GPT-4o、谷歌的Gemini以及DeepSeek的V3等模型。Grok-3具备“高级推理”能力，能够将复杂问题分解为更小的任务，并在提供解决方案之前进行事实核查。xAI还推出了名为Deep Search的Grok AI代理产品，旨在打造下一代搜索引擎。Grok-3提供“Think”和“Big Brain”两种推理模式，以满足不同复杂程度的任务需求。订阅X Premium Plus的用户可以使用Grok应用中的Grok-3推理功能。此外，xAI计划在未来几个月内开源Grok-2。

💡xAI发布Grok-3，算力是前代产品的十倍以上，早期测试显示其推理能力超越GPT-4o、Gemini和DeepSeek的V3等模型，具备“高级推理”能力。

🔍Grok-3提供两种推理模式：“Think”模式会展示Grok解决请求的推理过程；“Big Brain”模式适用于需要更多计算能力的复杂任务。同时，xAI还推出了Grok AI代理产品Deep Search，定位为下一代搜索引擎。

🗣️Grok-3力求“寻真”，即使真相与政治正确相悖。之前的版本曾因传播选举虚假信息和缺乏文本到图像生成的防护措施而受到批评。OpenAI也在探索如何在处理有争议的话题时，开发模型以“寻求真相”，但同时保持一定的安全措施。

💰Grok-3的推理功能面向X Premium Plus订阅用户开放，该订阅价格已上涨至每月40美元。xAI还计划推出名为SuperGrok的新订阅计划，提供“最先进的功能和最早的新功能访问权限”，价格为每月30美元。

🤖Grok将很快获得类似OpenAI的ChatGPT高级语音模式的合成语音功能。xAI还计划在未来几个月内开源Grok-2。

Elon Musk’s xAI unveiled Grok-3 on Tuesday, announcing that the new artificial intelligence model has “more than 10 times” the compute power of its predecessor. xAI said its latest flagship outperforms OpenAI’s GPT-4o, Google’s Gemini, and DeepSeek’s V3 models in early testing, and now features “advanced reasoning” capabilities.

So-called reasoning models are trained to answer more complex questions by breaking instructions down into smaller tasks and attempting to fact-check themselves before offering a solution, with the aim of providing stronger results. Similar models have been developed by rival companies, including OpenAI’s o1, DeepSeek’s R1, and Google’s Gemini Flash Thinking.

There are two Grok-3 reasoning modes available: “Think”, which will display Grok’s reasoning as it resolves requests; and “Big Brain” for complex tasks that require more computational power. xAI is also launching a Grok AI agent product called Deep Search, which the company describes as a “next generation search engine.”

Musk says that Grok-3 is a “maximally truth-seeking AI — even if that truth is sometimes at odds with what is politically correct.” Previous versions of the xAI chatbot have been criticized for spreading election misinformation and having fewer guardrails on text-to-image generation, allowing it to spit out questionable or offensive imagery. OpenAI is also exploring how to develop its models to “seek the truth” when handling controversial topics, but with the aim of maintaining certain safety rails.

The Grok-3 reasoning capabilities are available in the Grok app for subscribers to X Premium Plus, which now starts at $40 per month. This is the second hike for Premium Plus in two months, having increased from $16 to $22 in December. xAI said it is also launching a new subscription plan called SuperGrok that will provide “the most advanced capabilities and earliest access to new features.” SuperGrok will reportedly cost $30 per month, though it’s unclear if this is an additional charge on top of X subscriptions.

Elon Musk said that the Grok chatbot will soon gain a synthesized voice feature that sounds similar to OpenAI’s Advanced Voice Mode for ChatGPT. xAI is also planning to make Grok-2 open source in the coming months.
