Artificial intelligence ranking: from ChatGPT to Grok, which are the best and what each one is best for

In every technological race, there comes a point where all products in the same category become so similar that choosing the most suitable one becomes difficult. This is happening with Artificial Intelligence (AI) : there are many competitors, but only one golden spot. So, what are the most popular chatbots ? And, above all, what are the best uses for each one?

Leading companies are racing to democratize AI with ever-deeper integrations and models that combine millions of parameters to deliver immediate answers .

The big difference lies in the parameters : neural connections that are fine-tuned during training to make the model more rigorous. The more parameters it has, the more it will refine its reasoning and responses, although it will consume more resources.

The ranking provided by Global Market Insights , Harvard Business Review and Chatbot Arena indicates that the leader (in use) is ChatGPT , from OpenAI : 22%, followed by Google Gemini 17%, Microsoft Copilot 15%, Anthropic: 12%, Deepseek 11%, Grok 8%, Perplexity: 7%, Meta AI: 5%, others: 3%.

Until recently, most models were efficient at solving specific tasks —answering questions, translating texts, or generating summaries—but they did so without “understanding” what they were processing.

One of the biggest leaps forward was the advent of reasoning agents , such as OpenAI o3 and DeepSeek R1, trained with trillions of tokens and advanced architectures to analyze data, infer patterns, and simulate human thinking, from causes to consequences.

This unique capability brings them closer to what is known as AGI: an AI that thinks, learns, and decides like a person. And while it doesn't yet exist, it is considered the first real step toward a system that not only responds, but also reasons.

It stands out for its ability to capture nuances, context, and ambiguities in language. It generates more coherent texts than its competitors. In memory-enabled versions, it remembers preferences, style, and topics of interest.

The most advanced is GPT-4.5, a model capable of handling complex tasks within demanding workflows. It's ideal for those seeking creative results, long-form copy, sophisticated programming, or in-depth analysis.

Its great advantage is that it follows instructions exactly, making it a reliable option for tasks that require precision and context. However, its power comes at a price: it costs US$200 a month.

Google gradually lost its search engine supremacy amid the rise of AI. Although it started with a significant lead, it failed to capitalize on it, and in this headlong race, it ended up competing on equal terms with models that had previously lagged far behind.

The big contender to regain the lead is Gemini, a multimodal model that interprets text, images, and audio. Thanks to this comprehensive understanding, it offers faster and more realistic answers. The goal is for it to function as a personal assistant, capable of searching, understanding, and summarizing information, revealing details that traditional searches often overlook.

Until recently, these features were limited to premium plans, but now they're open to everyone. In addition, Flash Thinking Experimental version 2.0 is being added, bringing key improvements: file uploads, more advanced reasoning, and faster, more accurate responses.

Fully focused on analytics tools, Copilot not only processes vast amounts of data in seconds, but also translates it into smarter decisions. It's capable of anticipating with predictive insights, unraveling complex patterns, and displaying results as if putting together a visual summary ready for presentation.

Although it shares the same DNA as ChatGPT, Copilot plays at home in the Microsoft 365 ecosystem. It moves smoothly in Word, Excel, Outlook, PowerPoint, and Teams, where it acts as a silent but effective assistant, boosting work and saving steps without demanding attention.

Claude 4 demonstrates complex reasoning, precise coding, and the ability to perform long-term tasks as an autonomous agent. It has the potential to unravel complex questions, follow detailed instructions, and maintain coherence in long conversations. It excels particularly at logical reasoning and deep text comprehension tasks.

It handles up to 200,000 context tokens (approximately 150,000 words), allowing you to process long documents, long conversation histories, or multiple files without losing consistency or accuracy.

It was designed under "constitutional AI" principles, meaning it prioritizes responses aligned with ethical values ​​and avoids generating harmful or biased content.

This is a Large Language Model (LLM) of Chinese origin designed to assist in software development, natural language processing, and business automation. It competes directly with GPT-4, Claude, and Llama.

One of its main advantages is its open-source nature, allowing anyone to see its inner workings, install it locally, and use it freely. This contrasts with the closed approach of other proprietary models. Furthermore, the native chatbot is completely free and requires no subscription to access its more advanced model.

It is trained with a high proportion of code data (more than 80% in some models), making it ideal for: code generation and explanation, bug fixes, translation between programming languages.

Developed by xAI, Elon Musk's company for a bolder, less constrained conversational experience, it stands out for its "anti-woke" approach and willingness to tackle topics that other AI systems often avoid.

Trained with ten times the computing power of its predecessor, using the Colossus supercomputer, Grok 3 incorporates advanced features such as "DeepSearch" and "Big Brain," which enhance its reasoning and deep search capabilities.

Grok 3 has been criticized for its adult mode, which allows sexually explicit chats without strict age controls, and for generating inappropriate content and misinformation. These controversies have led xAI to strengthen its security measures and hire specialized teams.

Despite the tensions, it experienced significant growth in its user base, driven in part by its integration with the X platform and its distinctive focus on uncensored interaction.

It's an AI-powered conversational search engine that provides direct and contextualized answers, unlike traditional search engines that only display links. It uses advanced models such as GPT-3.5 and GPT-4, Claude 3, and Mistral Large (in its Pro version) for up-to-date replicas backed by reliable sources.

One of its strengths is real-time search, which allows you to access recent data, integrated into a fluid conversation through follow-up questions. This makes the experience more natural. It also includes tools like Spaces, which allows you to organize results into thematic folders. Available on multiple platforms, including mobile apps and a Chrome extension.

Meta AI's popularity was driven, in part, by its integration with WhatsApp, especially among teenagers, who take advantage of the assistant's accessibility within an app that is already part of their daily use.

Its features include image generation, personalized responses, internet searches, and the ability to adapt based on user corrections. In Europe, its use is limited by privacy regulations, and although Meta claims it does not access encrypted chats or train its models on these interactions, caution is advised when sharing sensitive information.
