This morning, around 8:00 AM PDT, “Grok 4” would have been announced with a xAI statement that promises to “revolution human decision-making.” Social networks, especially X, would be full of reactions ranging from emotion to new possibilities to fear for their possible consequences. Hashtags like #Grok4, #IARevolution and #xAI could be on the move. The holders of the technological sites probably describe it as “the next step towards the autonomy of the AI,” while critics are already warning about risks such as job loss or the need for ethical control.
Positive reactions
- Practical Enthusiasm: Users highlight how “Grok 4” could save lives by predicting and planning for hurricanes or earthquakes. A viral comment could be: “If this AI can organize evacuations in minutes, welcome the technological revolution.”
- Futuristic Optimism: Tech fans are excited by a more efficient world. Something like: “Imagine a Grok 4 managing entire cities. The future is already here and I am living for this. “
- Humor: Memes are not missing. A classic: “Grok 4 solving my life in 3 seconds while I keep looking for the keys.”
Negative Reactions
- Fear of Displacement: Professionals like economists or urbanists could feel threatened. A typical comment: “Great, another AI that leaves me without work. What’s next, president robots?”
- Ethical skepticism: There are those who question the power of xAI. For example: “Who controls Grok 4? I don’t trust a machine making decisions for me.”
- Social criticism: Some see it as an unnecessary luxury: “While the world is flooded, millionaires play with their AIs. Priorities, please.”
Why is it Viral
This topic has all the necessary elements to cause a great impact: real innovation, ethical dilemmas and a direct effect on our daily lives. The division between those who support the AI and those who are against fuels the debate, while the mission of xAI to “advance collective understanding” gives it a noble touch that invites reflection. In addition, the date (March 2025) coincides with a time when humanity seeks urgent solutions to global problems, which makes “Grok 4” feel like a very timely response.
Grok 3, which launched on February 18, 2025, was a game-changer for xAI, establishing itself as a serious contender against models like OpenAI’s GPT-4o and Google’s Gemini. With training powered by 200,000 NVIDIA H100 GPUs on the Colossus supercomputer, Grok 3 brought advanced reasoning capabilities, real-time search (DeepSearch), and even a “Mini” version for quick responses. Elon Musk claimed it was “10 times more powerful” than Grok 2, and its integration with X made it available to Premium+ users for $50 a month and SuperGrok for $30 a month. Given xAI’s rapid pace, it’s reasonable to think that Grok 4 might already be in the works or even announced by March 2025, following their trend of quick iterations.
New and New Expected Functions of Grok 4
Based on the trajectory of xAI and the demands of the IA market in 2025, here are the possible developments and functions of Grok 4:
- Multimodality Advanced:
- Grok 3 is already creating images using the Aurora model (which is based on FLUX.1) and promises to include a voice mode. Grok 4 could take this one step further by incorporating real-time video processing, more complex audio analysis (such as transcription in several languages) and generating 3D content, competing with companies like OpenAI, which is already investigating in these areas.
- Example: You could create short videos from text prompts or interpret emotions in voice recordings.
- Improved Reasoning with “Big Brain 2.0”:
- Grok 3 brought in the “Big Brain” mode to tackle complex problems like math, physics, and coding. Grok 4 might take this a step further by introducing a hybrid reasoning approach that blends symbolic logic with neural networks, which could help cut down on hallucinations and boost performance in benchmarks like AIME 2025.
- Possible improvement: Multi-step problem solving with interactive visual explanations.
- DeepSearch Evolved:
- The DeepSearch function of Grok 3 is responsible for scanning X and the web to provide detailed reports. With Grok 4, we could see the integration of academic sources, such as arXiv, and real-time IoT sensor data, which would make it a completely autonomous research tool.
- Example: Generate a climate report combining X publications, scientific articles and live weather data.
- Extrem customization:
- With access to X user data, Grok 4 could provide super-personalized responses, taking into account the history of publications, interests and behaviors. This is something Musk has suggested as part of his idea of “seeking the truth.”
- Example: “I know you like space, here you have an analysis of the latest SpaceX mission adapted to your previous questions.”
- Sustainability and Efficiency:
- Faced with the criticisms of Colossus’ high energy consumption, which has been pointed out for worsening smog in Memphis, Grok 4 could improve its design to be more efficient in resource use. This may be achieved through more effective distiled models or even with the incipient quantum computation.
- Integration with Other Musk Projects:
- It could be linked to Tesla (driving data analysis) or SpaceX ( trajectory simulations), expanding its utility beyond X.
Downloads and Users of the Grok App
The Grok app, which was launched for iOS in January 2025 and then expanded to Android and the web, has gained popularity at a surprising pace. Until February 2025, it was available free of charge in its beta phase for X users, while subscribers could access premium functions. Here I leave an estimate based on previous data and trends:
- X users like Base: X is projected to have about 500 million active monthly users in 2025. If Grok 3 is launched for all Premium users (estimated at about 10 million by the end of 2024, according to X publications), and assuming a growth of 50% after the launch of Grok 3, we could calculate that between 15 and 20 million users would have initial access.
- Downloads of the App:
- Grok’s iOS app had a successful launch in Germany on February 20, 2025, surpassing expectations. Compared to ChatGPT (50 million downloads in its first year), Grok could have reached 5-10 million downloads on iOS and Android combined for March, driven by the X base and the promotion of Musk.
- Factors: The free version (with limits) attracts casual users, while SuperGrok and Premium+ capture power users.
- Grok 4 growth: If Grok 4 launches today, the downloads could be triggered by 30-50% in the first month, reaching 15-20 million, especially if it includes disruptive functions such as video or advanced voice.
Extended Technical Analysis (Hipothetics)
Assuming that Grok 4 follows the xAI exponential improvement line, here goes a technical analysis based on Grok 3:
- Architecture:
- Model size: Grok 3 has rumors of 500B parameters (not officially confirmed). Grok 4 could scale to 1T parameters, taking advantage of Colossus, which doubled its capacity to 200,000 GPUs H100. This would put it in pairs of models like GPT-5 (expected in 2025).
- Optimization: Use of techniques such as Mixture of Experts (MoE) for efficiency, enabling only relevant subnets per task, reducing energy consumption by 20-30% compared to Grok 3.
- Training:
- Data: In addition to X and web publications, Grok 4 could incorporate synthetic data generated by Grok 3, an approach that DeepSeek successfully used in R1. This improves diversity and reduces bias.
- Computation: If Colossus operates at 100 exaFLOPS (estimated), Grok 4 could be trained in weeks, not months, with an energy cost optimized by thermal management software.
- Performance:
- Benchmarks: Grok 3 exceeded GPT-4o in AIME 2025 (mathematic reasoning). Grok 4 could aim at an ELO of 1500+ in Chatbot Arena, in front of 1400 of Grok 3, thanks to its improved reasoning.
- Latency: With Grok 3 Mini as a precedent, Grok 4 Mini could respond in ≤100 ms, ideal for real-time applications.
- Multimodality:
- Vision: Integration of a model such as advanced CLIP for image and video analysis, with 95% accuracy in recognition of complex objects.
- Audio: Voice processing with 50 ms latency, competing with the Omni mode of OpenAI.
- API and Scalability:
- The Grok 3 API, launched in October 2024, has a cost of 5 USD per million tokens of entry. Grok 4 is expected to reduce this price to 3 USD thanks to its increased efficiency, as well as a business API capable of handling up to 10,000 applications per second.
Conclusion
The conclusion is that if Grok 4 is launched in March 2025, it is very likely that it comes with advanced multimodal capabilities, more sophisticated reasoning and deeper integration into the Musk ecosystem, all with a focus on customization and efficiency. The application could reach between 10 and 20 million downloads by that time, and it has an explosive growth potential if the new functions manage to attract public attention. From a technical point of view, it would be a massive but optimized model, designed to stand out in benchmarks and usability.
