Nobody noticed right away. Artificial intelligence didn’t knock on the door: it sat down at the table and started talking. Reasoning. Creating things we hadn’t asked for. In 2026, the question is no longer whether to trust a machine that thinks, but which machine deserves our trust.
A few months ago I asked six artificial intelligences to solve the same problem. I received six different answers, all correct, none alike. That was the moment I understood: we are not choosing between tools, we are choosing between ways of thinking. ChatGPT that embraces everything. Gemini that sees everything. Claude that understands everything. DeepSeek that reasons in silence. Grok that listens to the world in real time. Perplexity that seeks only the truth. Each has chosen a path, and none of these paths is wrong.
This article is not a ranking. It is a map. And like every good map, it does not tell you where to go: it shows you where you can arrive.
The Six Protagonists
ChatGPT — The Universal Wildcard
If artificial intelligence were a stage, ChatGPT would be its most eclectic performer. OpenAI has built an ecosystem that embraces text, images, video, voice and code within a single interface. Projects, persistent memory, advanced voice mode: it is the fluidity of the whole that makes it the natural starting point for anyone seeking an all-round assistant.
Gemini — The Multimedia Eye
Gemini is the fusion of Google’s computational power with a deeply multimedia vision. With one million tokens of context and native integration across the entire Workspace ecosystem, it is not just a model: it is an infrastructure. Veo 3 for video, Nano Banana for images, AI Studio for prototyping and advanced model customisation. The latter, in particular, transforms Gemini into a true creative laboratory: it lets you experiment with prompts, parameters and workflows in an environment that breaks down the barriers between idea and realisation. If creativity needs a space to express itself without constraints, Gemini is that place.
Claude — The Narrator’s Soul
Where others chase speed, Anthropic has chosen depth. Claude Opus 4.6, with one million tokens of context, excels in writing quality, logical rigour and the analysis of complex documents. Its ability to maintain coherence across enormous contexts makes it an invaluable ally for those working with long texts, layered analyses or intricate codebases. Claude Code, available as a CLI and integrated into major IDEs, does not merely suggest: it explores, understands, builds. For the kind of work I do — where analytical precision matters as much as clarity of expression — Claude has become one of my most valuable collaborators.
DeepSeek — The Engine of Logic
DeepSeek proves that computational power need not be the exclusive domain of a few giants. Its R1 model, with 671 billion parameters, achieves results comparable to the best proprietary models at a fraction of the cost. Above all, it is completely open: anyone can use it, modify it, redistribute it without commercial restrictions. The web interface is free, the model weights downloadable. A pure reasoning engine, deliberately essential in everything else. One aspect to consider carefully: data processed through the web interface and APIs passes through servers located in China, subject to local data security regulations. Several countries have already imposed restrictions on the use of DeepSeek on government devices. For those handling sensitive information, the alternative is to run the model locally on your own servers, leveraging the open-source nature of the project.
Grok — The Echo of the Moment
The AI that never sleeps. Its symbiotic link with X gives Grok a unique edge: real-time access to the global stream of conversations, news and trends. DeepSearch scans the internet and the platform for in-depth summaries. Aurora generates photorealistic images in five seconds. Grok 4 Heavy has achieved a symbolic milestone: it surpassed 50% on Humanity’s Last Exam, a benchmark created by the Center for AI Safety with 2,500 advanced academic questions across over a hundred disciplines, designed to be the last frontier before AI reaches human expert competence. For those who turn trends into opportunities, Grok is indispensable.
Perplexity — The Compass of Truth
It is not an assistant to chat with: it is a meticulous researcher. Every answer comes with numbered citations linking directly to original sources. Pro Search reasons in multiple steps, Spaces organises research into persistent libraries. In an era when artificial hallucinations pose a real risk, Perplexity turns verifiable transparency into its competitive advantage. It is no coincidence that law firms like Gunderson Dettmer have adopted it company-wide, with 80% of their lawyers using it daily for over 35,000 queries per month. Or that universities such as American University and Texas A&M are integrating it into academic research paths, thanks to a partnership with scientific publisher Wiley for direct access to peer-reviewed content. Where accuracy is not optional but a professional obligation, Perplexity has become the standard.
It is not the most powerful machine that makes the difference. It is the mind that knows when to silence it and when to let it speak. Artificial intelligence amplifies who we are: our best intuitions, but also our worst laziness. Choosing the right model is, first and foremost, an act of awareness. — Giovanni Aduso
True Intelligence Remains Our Own
Three years ago, the idea of choosing among six specialised artificial intelligences would have seemed like science fiction. Today it is our daily reality, and the speed at which this landscape evolves has something both sublime and unsettling about it. Every quarter a new model redefines the boundaries of the possible. Every month a feature that seemed futuristic becomes the default.
The temptation is to search for the “absolute best”. But that would be like asking which is the finest musical instrument: it depends on the symphony you want to play. ChatGPT for everyday versatility. Gemini for shaping images and video. Claude for the depth of an analysis or the cleanliness of code. DeepSeek for pure, democratic reasoning. Grok for the pulse of the present. Perplexity for the certainty of sources.
The professional of 2026 is not the one who masters a single AI. It is the one who knows how to orchestrate the right combination for every challenge, who recognises the moment to switch from one tool to another, who maintains critical judgement when the machine produces results that seem perfect. Because the true revolution is not in artificial intelligence itself. It is in how it amplifies — or betrays — the intelligence of those who use it. And that intelligence, in the end, remains irreducibly our own.
