Analysis: Choosing an AI model to use means making a call between different ecosystems and tools based on issues of data, privacy, cost and trust
Artificial intelligence has moved from novelty to necessity. The systems we once treated as party tricks are now drafting essays, analysing data, generating code and even advising governments. But there is no single "AI." Instead, several rival models are competing for dominance: ChatGPT, Gemini, Grok, DeepSeek and Claude. Each represents a different approach, ecosystem and vision of what artificial intelligence should be.
Understanding these differences is not an exercise in brand-spotting. These models are gateways into wider ecosystems that carry distinct assumptions about data, privacy, cost and trust. The choice of tool is not trivial. It shapes how we work, how we learn and how information itself is filtered and presented.

From RTÉ Radio 1's Brendan O'Connor Show, can AI write better poetry than a poet?
ChatGPT is the most recognisable name, and for good reason. OpenAI's flagship, backed by Microsoft has become the default entry point for millions. Its appeal lies in versatility: the ability to switch between generating a business plan, revising code, drafting a speech or even analysing an image. Yet that same flexibility exposes its weaknesses. ChatGPT is quick and fluent, but not always accurate, and its most advanced features sit behind a paywall. It is a capable generalist but, like any generalist, it occasionally sacrifices depth for speed.
If ChatGPT positions itself as the universal assistant, Google’s Gemini has chosen a narrower, more embedded path. Rather than offering everything to everyone, Gemini integrates directly into Gmail, Docs, Sheets and the broader Workspace suite. Where ChatGPT aims to dazzle with breadth, Gemini tries to fade into the background, smoothing the daily frictions of office life. Long email chains shrink into neat summaries, slides assemble themselves from text, and data tables yield quick insights. For those already invested in Google’s ecosystem, the effect can be transformative. As a standalone chatbot, however, Gemini has yet to build the same following or distinct identity.

From RTÉ Radio 1's Drivetime, how ChatGPT is now offering therapy
Not all competitors are chasing the office crowd. Grok, developed within Elon Musk's X (formerly Twitter), is built for a different audience altogether. Where Gemini seeks to be invisible, Grok insists on personality. Closely tied to the live flow of posts on the platform, it generates commentary with a conversational, sometimes irreverent style. It reflects the tempo and tone of X itself: fast, chatty and often provocative. This makes it intriguing for heavy users of the platform but, beyond this niche, Grok remains far less capable than its more established rivals.
DeepSeek highlights a different dimension of the AI race. Developed in China, it markets itself as significantly more cost-efficient than Western rivals while delivering strong performance in mathematics, coding and data-heavy analysis. Its promise is affordability at scale. In China, it has already attracted attention as a domestic alternative; internationally, adoption will be shaped as much by politics as by technical benchmarks. Still, its rise underscores that the future of AI is not confined to Silicon Valley and competing national models are becoming part of the global landscape.

From RTÉ Radio 1's Drivetime, why China's new DeepSeek AI is a game-changer
Created by Anthropic, Claude offers a counterpoint to all of the above. Where ChatGPT prizes versatility, Gemini integration, Grok personality and DeepSeek efficiency, Claude emphasises caution and depth. It can process very long documents (entire books or lengthy legal texts) and responds with measured reasoning rather than quick-fire quips.
It is also designed to reduce errors and avoid the overconfidence that plagues other systems. This makes it appealing to researchers, lawyers and policymakers who need careful analysis more than creative sparks. Its limitations are equally clear: it lacks multimodal abilities like image or audio processing, and its restraint can frustrate users seeking faster or freer brainstorming.

From RTÉ Radio 1's Liveline, listeners call in about how AI is helping Irish farmers
Taken together, these systems are not simply competing products but competing philosophies. ChatGPT suggests that the future lies in breadth, a single tool that can do almost everything. Gemini argues for quiet embedding, making AI part of the everyday workflow. Grok imagines AI as entertainment and commentary, reflecting the culture of a platform. DeepSeek demonstrates how affordability and scale may matter as much as raw innovation. Claude holds out for restraint and depth, favouring trust and accuracy over speed.
The choice between them is less about technical specifications than about the kind of relationship we want with these systems. A student brainstorming an essay may find ChatGPT’s fluency invaluable, but a manager in a Google-driven workplace will appreciate Gemini’s seamless integration. A journalist tracking trends on X may turn to Grok, while an engineer running large-scale analysis could favour DeepSeek. A well-paid lawyer parsing case law may trust Claude above the rest. Each model reflects different compromises between creativity and accuracy, convenience and control.

From RTÉ Radio 1's This Week, RTÉ Work and Technology Correspondent Brian O'Donovan on new AI transparency rules which have come into effect in Europe
These compromises are not just personal and have wider social and political consequences. Platform rivalries are not new: we have lived through Windows versus Mac, Android versus iOS. Those earlier battles shaped the devices in our hands, but the AI contest is shaping how knowledge itself is produced and circulated.
When these models generate our reports, rewrite our essays or filter our news, they are not only saving us time. They are influencing which facts are highlighted, which arguments are emphasised, and which voices are amplified. This is why governments are paying attention. The European Union's AI Act, China's state-led investments and America's corporate alliances all signal that these models are not neutral tools. They are built within political economies, guided by cultural assumptions and shaped by national ambitions. The choice of which AI to use is not just a matter of personal taste. It is also a civic choice, carrying implications for trust, safety and sovereignty.
These systems are not toys or passing fads, but are becoming the scaffolding of our information environment
For the public, the challenge is to move past the question of which AI is "best." There is no single winner, only different trade-offs. The better question is what you need the system for, which ecosystem you are willing to enter and how much risk you are prepared to accept. AI literacy today is not about mastering technical jargon, but recognising the values and compromises built into each of these tools.
New names will join this race, just as old ones will fade. Marketing will continue to promise simple answers, but the truth is more complex. These systems are not toys or passing fads. They are becoming the scaffolding of our information environment. The real question is not whether AI will influence our decisions, but whether we remain alert to how, and on whose terms, that influence is exercised.
