Top 3 Large Language Models (and Why ChatOn Uses Them All)

May 30, 2025

Doesn’t it seem like AI these days understands you better than a human? No awkward responses, just helpful, on-point answers. That’s the power of large language models (LLMs), and with ChatOn, we’ve brought together the best of the best. Built on such top models as GPT-4, Claude, and DeepSeek, the app offers smarter, faster, and more accurate interactions than ever before. Ready to see how it works? 

What Is an LLM (and Why Should You Care)? 

An LLM (Large Language Model) is the brain behind all the AI chatbots, writing assistants, and smart search features. It’s what makes AI understand your questions and respond in a way that feels natural and useful. 

You’ve probably used chatbots before—for customer support or booking a ticket. Most of them rely on pre-written scripts, which means if you don’t phrase your question exactly right, they might not get it. LLMs, on the other hand, learn from massive amounts of text. They don’t just scan for keywords but analyze meaning, tone, and intent. This makes interactions much more natural. 

How Do LLMs Work? 

At their core, any LLM does one thing: 

You give it a prompt → It predicts and generates the most relevant response.

Think of large language models as supercharged auto-complete, but way smarter. Instead of just guessing the next word, they understand the context of your question and generate a response that actually makes sense. That’s why AI tools can help with everything from writing and summarizing documents to answering customer support questions and even coding. And ChatOn is one of the vivid examples. 

However, unlike many similar tools on the market, ChatOn isn’t built on just one AI model. It uses multiple LLMs, each with its own strengths. Let’s get to know them better. 

The AI Power Trio behind ChatOn 

Apps like ChatOn use different large language models because no single AI is perfect for everything. Think of it like a team—each member has a special skill, and together, they get the job done better. 

🧠 The Creative Thinker: GPT-4 

Developed by OpenAI, GPT-4 is one of the most powerful language models available. It’s fast, highly capable, and incredibly versatile. We trust these two quick minds—GPT-4o and GPT-4o mini. When it comes to AI content generation, they can handle literally everything, from creative writing to complex problem-solving. Need to create a resume? We can’t imagine hands more helpful for your everyday tasks! Plus, we can rely on GPT-4 to create images for you.

🤝 The Responsible Guide: Claude 

It’s widely considered that Claude is created with a strong focus on safety and ethics. We use it in ChatOn to help reduce bias, misinformation, and harmful outputs for you. There are two versions we rely on, each with its own perks. One of them is Claude 3 Haiku, loved for its speed. Another one is Claude 3.5 Sonnet, which is overall on par with GPT-4o but we find it especially great at math, coding, and logical problem-solving. So you can get an extra edge in analytical tasks! 

🔍 The Insights Expert: DeepSeek 

DeepSeek is a specialized AI model designed for data retrieval and deep analysis. Just like a diver exploring the depths, it searches through large datasets to uncover meaningful insights. We understand that some of our users need exactly that, which is why ChatOn includes it. A key point to note: the DeepSeek model we use runs on American servers, and we do NOT share any data with China.

And the best thing is that in ChatOn you can choose the large language model that suits you best. Just tap the model name above the text input field and select your preferred one in the chat settings. 

What’s in It for You? 

Each of these models—whether it’s GPT-4, Claude, or DeepSeek—brings something special to the table. And when you download an app built on various LLMs, it means you get a more powerful, multitasking tool. But what else? 

✅ You get more accurate answers 

Have you ever asked two friends the same question and gotten slightly different answers? AI is the same way. With multiple models at hand, it’s possible to cross-check responses and avoid mistakes. That means you get more trustworthy and well-rounded answers, whether you’re asking about travel tips, coding, or medical advice. 

⚡ You get the best possible performance 

Some AI models are super powerful but take longer to respond, while others are faster but less detailed. With multiple large language models at hand, you get quick replies when you need them and deeper insights when it matters.

By using multiple technologies, ChatOn keeps up with the latest advancements. So, our users always have access to the best AI tools available, without even noticing the upgrades.
