In a world where technology evolves faster than ever, Artificial Intelligence has gone from sci-fi fantasy to an everyday reality. AI has woven into our lives, helping us write essays, suggest songs, code apps, or even pick a restaurant. But with so many tools out there, it can be hard to know what to use. The guide breaks down the top AI models, what makes each one special, and my personal favorites for different tasks. This post reflects my personal opinions and experiences. All trademarks and product names are the property of their respective owners.
What is AI?
Before I jump straight into the main topic, allow me to provide you with a little background of what AI is. Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. AI enables computers to perform tasks that typically require a lot of human thinking, in a matter of seconds.
AI-powered applications and devices can identify objects visually, understand and respond to human language, learn from new information, and provide detailed recommendations. They can also operate independently without human intervention, as seen in self-driving cars.
1. ChatGPT
ChatGPT is one of the most popular and widely used large language models, developed by OpenAI. Since its public release, it has become a household name in AI technology. This is a favorite amongst most, due to its all-around characteristics. From coding, to party planning, this AI is capable of pretty much anything and is advancing as we speak. Currently, the latest publicly released GPT model is GPT-4.1, which was released in April 2025. This release includes GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano models available through the API, and some of the improvements have also been integrated into GPT-4o.
2. Claude.ai
In my opinion, Claude is one of the best AIs for web development with HTML and CSS. It also has substantial writing capabilities as well. Claude AI is a next-generation AI assistant created by Antrhopic, that can be used for a variety of tasks, including witing, coding, research, and more, both through a chat interface and API. It surpasses GPT in terms of writing due to its ability to write long, more detailed, and more human sounding content. ChatGPT is quite good at writing, but it tends to produce mechanical-sounding paragraphs and overuses long dashes (—).
3. Google Gemini
Gemini is Google's flagship large language model. It's distinguished by its clean interface, exceptional multimodal capabilities (processing text, images, audio, and video), strong performance in coding, information synthesis, and complex reasoning tasks. Unlike some competitors, Gemini excels at maintaining context over long conversations and can be accessed through Google's Bard interface or via API. The latest version, Gemini 1.5 Pro, features an impressive 1 million token context window, allowing it to process extremely large documents and maintain coherence across extensive exchanges. I also found it remarkably easy to obtain an API key, which is very helpful while coding simple AI bots.
4. Perplexity AI
Perplexity AI is an AI-powered search engine and chatbot that aims to provide users with direct, conversational answers to their questions, citing sources within the text. It distinguishes itself from traditional search engines by synthesizing information from various sources and presenting it in a clear, concise manner, rather than just providing a list of links.
This tool can be extremely helpful for research, learning, and staying informed.
5. Bolt.new
Bolt, developed by the team at StackBlitz, utilizes a sophisticated tech stack designed. to enable full-stack web application development directly within the browser. This model uses JavaScript-based frameworks and libraries, including React, Vue, Svelte, Angular, Next.js, Astro, Vite, Remix, and Tailwind CSS. This is an extremely helpful tool for web development of complex projects, especially since it allows you to connect your project to a database, enabling you to create even more sophisticated applications.
6. Lovable.dev
Lovable.dev is an AI-powered platform quite similar to bolt.new. However, Lovable emphasizes a no-code approach with a strong focus on collaboration and backend reliability, while Bolt.new excels at rapid front-end prototyping and code-assisted development. Lovable generates a more polished app from the start, while Bolt.new offers faster code generation and allows direct code editing.
7. LLaMa
LLaMa (Large Languauge Model Meta AI) is Meta’s open-source AI family. It’s not just one model, its a large group, designed to be lean, powerful, and high adaptable. LLaMa started making huge waves in 2023 when Meta dropped LLaMA 2 for public research + commercial use. That was a game-changer, because most big models like GPT-4 were locked behind APIs and black boxes. As of LLaMA 3 (released in 2024), Meta pushed even harder, matching the quality of GPT-4 while still being open and remixable. Tons of smaller startups now use LLamA as their base model to build personalized chatbots, roleplayers, or task agents. LLaMA is ultimately the backbone of innovation, giving developers, researchers, and tinkerers full access to the core brain and saying: “Build whatever you want”.
8. Grok
Grok is the chatbot developer by xAI, Elon Musk’s own AI company, and it lives inside X (formerly Twitter). It’s basically the neutral cousin of ChatGPT with a personality and direct pipe into live tweets. This chatbot is not afraid to be political or “go there”, Grok sometimes roasts politicians, gives feedback, or uses memes mid-response. Some people love it for being less censored that ChatGPT, others think its trying too hard to be funny. Either way, it gets people talking.
9. GitHub CoPilot
Copilot is the AI version of a coding soulmate. Built by GitHub + OpenAI, it’s designed to sit beside you in the code editor and whisper full functions, logic, or even full-stack structures before you even finish typing. It’s powered by Codex, which is like GPT-3 fine-tuned on open-source code. It’s extremely useful to have this chat right beside you while programming. It even works contextually, so you if you highlight a block of code, it tailors the response to just that snippet.
10. Apple Intelligence and Siri
Apple Intelligence is Apple’s new AI system announced at WWDC 2024, built natively into iPhone, iPad, and iMac. It’s not just a single app, its a full-on AI layer across the system that’s private, personal, and very powerful. It contains helpful features such as text rewriting, summarizing, proofreading, image generation, and contextual awareness.
Siri is Apple's virtual assistant. Siri and Apple Intelligence work together, but serve different functions. For example, you might ask Siri, "Text Robert, What restaurant are we eating at with the group on Friday?" Siri will then respond: "Here's your message to Robert: What restaurant are we eating at with the group on Friday? Ready to send?" Behind the scenes, it's Apple Intelligence that understands the context, recognizes the contact, and creates a seamless experience. Simply put, Siri is the voice, while Apple Intelligence is the brain.
How does AI work?
AI is complex, but fairly simple to understand. Artificial Intelligence works by learning from massive amounts of data to recognize patterns and make predictions. Think of AI like a student studying millions of examples to understand how things work. Modern AI uses neural networks, which are computer systems inspired by how brain cells connect and communicate. These networks start by making random guesses, but as they process more examples, they get better at recognizing what's correct. Through this training process, AI systems gradually learn to identify images, understand language, or solve specific problems by finding patterns in the data they've seen.
Once an AI system is trained, it can be put to work solving real-world problems. Companies and researchers feed their AI systems carefully organized data, then test and refine them until they perform well on specific tasks. Different types of AI are designed for different jobs - some excel at recognizing faces in photos, others at translating languages, and others at playing games or driving cars. When you interact with AI today, whether through a voice assistant, recommendation system, or chatbot, you're experiencing the result of these systems applying what they learned during training to understand your input and provide helpful responses.
My Go-To Tools
My daily AI toolkit varies depending on the task at hand. Each of the AIs mentioned above specializes in different areas. For coding projects and development work, I rely on GitHub CoPilot. When I need to learn something new or conduct research, I typically turn to AI models like ChatGPT or Google Gemini. When it comes to encorporating AI into projects, I often use LLaMA or Cluade 3.7-sonnet as those are the easiest to use, yet still powerful.
The Dangers of AI
AI is helpful, but its important not to let it take over. AI tends to make us lazy, dependent, and less likely to problem-solve. The simple reason given is that everything we need is at our finger tips, whether it's the answer to a math problem, or a solve to a coding error. Utilizing AI as a tool is smart, but just make sure you can still achieve tasks without it.
Another danger that AI brings, is potential harm to our environment. Supercomputers are used for training large AI models, and complex AI systems. But something we have to consider is that this super computer has to be placed somewhere, often outside. AI supercomputers significantly impact the environment through high energy consumption, water usage, and electronic waste generation. The energy demands of training and operating AI models, particularly in data centers, lead to increased greenhouse gas emissions and reliance on fossil fuels. Furthermore, the cooling systems required for these data centers consume vast amounts of water, potentially straining local water resources. Finally, the short lifespan of AI hardware contributes to a growing problem of electronic waste.
Summary
As we move forward into the world of AI, these tools are just the start of what’s possible when technology works with human creativity and problem-solving. Tools like ChatGPT, Claude, Bolt, and LLaMa all have their own strengths, whether it’s writing, coding, or being open-source. They can really help with both work and everyday tasks.
But as we start using AI more, it’s important to remember to keep building our own skills and not rely too much on the tech. We should also think about how AI affects the environment. The best way to use these tools is with balance, letting them support us, not take over. If we understand both the good and the risks, we can use AI in a smart, responsible way that helps us do even more in our connected world.
