Elon Musk's xAI has officially launched Grok 3, its latest AI model, which Musk has dubbed the "smartest AI on Earth." Trained on 200,000 GPUs, this new model is positioned as a direct competitor to OpenAI's GPT-4 and DeepSeek, excelling in math, science, and coding benchmarks. The launch appears to coincide with a price hike for X Premium+ subscriptions, offering initial access to Grok 3 for subscribers in the U.S., with a separate subscription planned for web and app versions.
xAI's Grok 3 comes with advanced reasoning and agentic abilities and uses more than 10 times the computing power of Grok 2. It has two modes: "Think," which uses a smaller Grok 3 mini model for simple queries, and "Big Brain," which utilizes Grok 3 for complex problems. A new agentic feature called DeepSearch, conducts comprehensive analyses and generates reports, similar to tools recently released by OpenAI, Google, and Perplexity. Recommended read:

Elon Musk's AI venture, xAI, has launched its Grok chatbot as a free app for iOS users in the US. The app allows users to access xAI's Grok 2 language model, enabling them to ask questions, create images, and analyze uploaded photos. Grok sets itself apart by pulling real-time information from X, formerly known as Twitter, and the web to provide current answers. This release marks xAI's continued effort to compete in the conversational AI space, particularly against rivals like ChatGPT. Currently, the app is only available to iPhone users within the United States.
In addition to the app launch, xAI is also making significant advancements with the development of Grok-3. It has been reported that xAI is utilizing 100,000 NVIDIA H100 GPUs to power the training of the Grok-3 model which is rumored to be the 'most powerful base model in existence'. This massive computational undertaking indicates a strong commitment to pushing the boundaries of AI capabilities. The pre-training for Grok-3 has recently been completed, and the model is expected to be released in the next 3-4 weeks, raising the question if it will outperform existing competitors and also resolve the question about whether additional computing yields diminishing returns.

Elon Musk's xAI has acquired Hotshot, a startup specializing in AI-powered video generation. Hotshot, founded by Aakash Sastry and John Mullan, has developed three video foundation models: Hotshot-XL, Hotshot Act One, and Hotshot. The move signals xAI's intention to enter the AI video generation market, potentially competing with OpenAI's Sora and Google's Veo 2.
The acquisition will see Hotshot's models scaled on xAI's supercomputer, Colossus, which utilizes a vast number of Nvidia chips. Hotshot trained its models on 600 million video clips, employing techniques like neural networks for automatic captioning and the bfloat16 data format to accelerate AI training. The company discontinued new video creation on March 14, 2025, and allowed existing users to download their content until March 30. Recommended read:

xAI, led by Elon Musk, has launched Grok-3, the latest iteration of its large language model, boasting advanced reasoning capabilities. The company claims that Grok-3 represents a substantial advancement over its predecessor, Grok-2, due to its "reasoning models" that mimic human thinking. Researchers added it was trained using significantly more compute power, and early testing suggests it may outperform models from OpenAI and DeepSeek. Grok-3 features both a large complex model (Grok-3 Reasoning beta) and a small fast model (Grok-3 mini Reasoning) for generating responses to complex questions.
To access the reasoning capabilities, users can engage "Think" mode and "Big Brain" mode for more complicated queries. Grok-3 can be paired with "DeepSearch," to scan the internet for relevant knowledge to incorporate into its answers. However, the launch has not been without controversy, as reports have surfaced that Grok-3's search results are being censored. Users have reported that Grok-3 is ignoring sources identifying Elon Musk or Donald Trump as misinformation spreaders. Additionally, Grok-3 is highly vulnerable to indirect prompt injection, where malicious instructions can be inserted into tweets, causing Grok to misbehave in response to certain queries.

Elon Musk's xAI has launched Grok 3, a new artificial intelligence model designed to compete with leading AI systems like ChatGPT, Gemini Ultra, and Qwen 2.5-Max. Grok 3 focuses on next-level reasoning, real-time data integration, and multimodal interactions, processing both text and images, with audio capabilities planned for the future. It aims to tackle academic challenges and real-world professional tasks.
Grok 3 boasts features such as DeepSearch for real-time web and X data retrieval and a 'Think' mode for detailed problem-solving. It also exhibits coding proficiency, writing, debugging, and optimizing code. xAI has incorporated Reinforcement Learning from Human Feedback (RLHF) to minimize bias and misinformation, aiming for trustworthy results. Grok 3 is designed to be an unfiltered AI model as OpenAI, Anthropic and Google filter training data to exclude harmful content. Recommended read:
