What Is Grok 3?
The newest AI model from xAI, Grok 3 AI, is positioned to directly compete with DeepSeek’s R1 and OpenAI’s o1. According to the xAI team, it is 10–15 times more powerful than Grok 2, and judging on the benchmarks shown in the demo, it may even be able to compete with the top models available.
How are reasoning models different?
Most AI models operate as follows: If you’ve used ChatGPT, Claude, or Gemini, you’re probably acquainted with this process.
Grok 3 AI and other reasoning models adopt a different strategy. They break down difficulties step by step, demonstrate their intermediate ideas, and even polish their output before offering a final solution, as opposed to just spewing out an answer right away. Because of this, they are very effective in arithmetic, coding, and solving practical problems.
Grok 3 Mini
Not all tasks need Grok 3’s full-scale logic. Grok 3 AI small retains Grok 3’s reasoning capabilities while being optimised for speed and less computation.
Developers that wish to maximise their token use expenditures while utilising the API may find Grok 3 mini particularly helpful.
A quicker response in the chat interface might be achieved by switching to Grok 3 Mini. There won’t be many queries it can’t answer based on the benchmarks.
Grok 3 Think Mode
Grok 3’s multi-step reasoning process may be activated by selecting the optional Think mode setting. It breaks issues down into smaller parts, considers several answers, and then refines its response before producing a final conclusion, as opposed to leaping directly to an answer.
Complex problem-solving, mathematical proofs, coding challenges, and logic-based tasks are especially well-suited for this mode. It is perfect for circumstances when the calibre of reasoning is more important than speed since it emulates human-like ordered thinking.
Grok 3 AI is being positioned by xAI as a generalist and thinking model. It functions more like GPT-4o or Claude 3.5 Sonnet when Think mode is off; it is quick, conversational, and designed for everyday use. However, it enters reasoning mode when Think mode is engaged, dissecting intricate issues one step at a time.
The benchmarks make this mixed approach even more evident. xAI evaluated Grok 3 AI against generalist models like GPT-4o, DeepSeek-V3, and Claude 3.5 Sonnet as addition to reasoning models like OpenAI’s O1 and DeepSeek R1. This implies that they would want it to compete in both categories as opposed to just one.
Grok 3 Big Brain Mode
Grok 3’s high-performance setting, Big Brain mode, allocates more processing power to tackle challenging tasks.
Grok 3 AI takes longer to process queries when enabled, but it provides more thorough answers, deeper insights, and greater accuracy. When normal inference may not be sufficient, this mode is very helpful for scientific study, multi-layered AI activities, and extremely complicated problem-solving scenarios.
Grok 3 DeepSearch
xAI’s integrated research tool, DeepSearch, enables Grok 3 AI to search the web, validate sources, and compile up-to-date material before producing a response.
DeepSearch is perfect for news, market trends, technical research, and fact-checking since it gathers new data, unlike typical AI models that rely on pre-trained data. With this mode, Grok 3 AI is positioned to compete with Deep Research from OpenAI and Gemini.
How Was Grok 3 Developed?
Grok 3 AI is based on a significant increase in processing power, novel training methods, and infrastructure improvements. To aid in the creation of Grok 3, xAI has built one of the biggest AI training clusters in the world, in contrast to its predecessors, which were taught on very less hardware.
xAI’s bespoke supercomputer, Colossus
The availability of computing power is one of the main obstacles to training large-scale AI models. xAI created their own supercomputer cluster, Colossus, to circumvent this (the warehouse is shown in the top image).
In just 122 days, the first phase deployed 100,000 H100 GPUs, making it one of the world’s biggest clusters for AI training.
In 92 days, xAI quadrupled the computing capability in the second phase. Because of the ongoing training made possible by this architecture, Grok 3 AI continues to advance in real time as more people engage with it.
From Grok 0 to Grok 3
Although Grok 1 had individuality, it was far from as good as Claude 3.5 Sonnet or GPT-4o when it was published in November 2023. Only a few months later, Grok 2 came out, and while it was significantly better, it was still not as good as the best models.
But Grok 3 AI represents a considerably larger leap. The team asserts that both model enhancements and a significant boost in training computation have made Grok 3 10–15 times more potent than Grok 2.
How to Access Grok 3?
Grok 3 AI is being rolled out gradually by xAI, with broader availability anticipated in the upcoming months. Grok 3 will be available to us through the API and a chat-based interface.
Chat-based interface
At the moment, Premium+ users may access the model, which is incorporated into X (previously Twitter). Like earlier Grok versions, users may speak with it straight within the platform.
In addition to X, xAI has introduced grok.com, a stand-alone online interface that allows users to communicate with the model outside of social media. Grok is not yet accessible in the UK or the EU via this website.
Grok 3 API
Grok 3 has not yet been made accessible via the API, but it will probably be in the near future.
