Grok is a generative artificial intelligence chatbot developed by xAI in 2023 as an initiative by Elon Musk. It is available to X users with a Premium+ subscription. This model is designed to answer almost every question with a touch of humor and wit while providing helpful and insightful responses. It is a large language model (LLM) that is capable of processing and understanding human language, text generation, summarization, and question-answering.
Grok 1 is considered the raw base model and was not fine-tuned for specific applications, allowing developers to access and utilize its capabilities freely. Grok 1.5 was released to all Premium users on May 15, 2024, and it has significant upgrades like improved reasoning capabilities, a larger context length, and the ability to process both text and visual information.
Grok 2 was released on August 14, 2024, and it is a small but capable model that offers a balance between speed and answer quality. Recently, on February 17, 2025, xAI released its latest AI version- Grok 3. This article will discuss Grok 3 and what it offers. So, keep reading to find out more.
An Overview Of Grok 3
Grok 3 is the latest model from xAI and Elon Musk stated that this model is trained with ‘10x’ more computing power than its predecessor. It has expanded datasets that reportedly include legal filings, and claims to outperform OpenAI’s GPT-4. This model is said to perform better across science, math, and coding benchmarks than Google’s Gemini, Anthropic’s Claude 3.5, and DeepSeek’s V3 models.
The xAI also introduced Grok 3 mini, which offers much faster responses at the cost of some accuracy. Also, xAI is focused on bringing reasonable capabilities similar to reasoning models like OpenAI’s o3-mini and DeepSeek’s R1, which allows users to tap ‘Think’ to enable reasoning or active ‘Big Brain’ mode for complex problem-solving. Musk announced that there will be a ‘voice mode’ for Grok 3 that is similar to the natural conversation feature of competitor apps like ChatGPT.
However, Grok 3 is limited to X’s Premium+ and xAI’s SuperGrok subscribers and after this announcement was made, X raised the price of its Premium+ subscription to $40 per month from $22.
Is Grok 3 The Most Powerful AI In The World Right Now?
Grok 3 enters the AI field competing with OpenAI’s o1 and DeepSeek’s R1. The Grok 3 model is said to be advanced because, unlike general-use models like ChatGPT, which generates answers outright, reasoning models have a thinking process, and the ability to break down problems step by step to arrive at a conclusion. The xAI presents Grok 3 as a reasoning model and a generalist AI with Think Mode and Big Brain mode. Grok 3 stands out because of its Think Mode and Brain Mode.
The Think Mode takes a different approach because rather than spitting out an answer immediately, they break down the problems step by step, share their intermediate thoughts, and even refine their output before resenting a final response. It mimics human-like structure thinking, making it ideal for situations that need quality reasoning rather than speed. This feature makes them powerful with tasks like coding, math, science, and real-world problem-solving.
As for Grok 3 Big Brain Mode, it offers a high-performance setting, which allocates extra computational resources to handle demanding tasks. Enabling this mode will take longer to process queries but will deliver higher accuracy, deeper insights, and more detailed responses. This mode is mostly used for highly complex problem-solving scenarios, scientific research, and multi-layered AI tasks.
About Grok 3 Mini
Grok 3 Mini was launched along with Grok 3 because not every task requires the full-scale reasoning of Grok 3. The Grok 3 Mini is optimized for speed and lower computing usage while offering the Grok 3’s reasoning capabilities. This model is useful for developers who wish to optimize their spending on token usage while using the API. That is, this model is ideal for users who prefer speed over accuracy. Also, one can switch to Grok 3 Mini for a faster response in the chat interface and based on the benchmarks, there won’t be many questions it cannot handle.
Conclusion
Grok AI is a generative AI chatbot developed by Elon Musk’s company xAI. This AI model is designed to provide insightful answers by accessing real-time data from the X platform, which allows it to engage in conversations other AI models might avoid. Grok 3 is the latest model by xAI, released on February 17, 2025, which is introduced to understand significant questions about the universe. This model is exclusively available for X users with a Premium+ subscription.
Grok 3 stands out from the rest of the AI models mainly because of its two modes: Think Mode and Big Brain Mode. Think Mode is an optional setting to activate Grok 3’s multi-step reasoning process rather than arriving straight at an answer. On the other hand, Big Brain Mode offers high performance and delivers high accuracy, deep insights, and detailed responses. Also, Grok 3 is said to outperform competing AI models across multiple industry-standard benchmarks.
