Disclaimer I love exploring new technology, and that includes using AI to help with research and editing! My digital &#8220;team&#8221; includes tools like Google Gemini, Notebook LM, Microsoft Copilot, Perplexity.ai, Claude.ai, and others as needed. They help me gather insights and polish content\u2014so you get the best, most up-to-date information possible.<\/p>\n\n\n\n<p>ALthough not much has changed, I am revisiting this topic  ( Original 2024 post: <a href=\"https:\/\/jorgep.com\/blog\/what-are-large-language-models-llm\/\" data-type=\"post\" data-id=\"465083\">What are LLMS<\/a> ) as it has been a while, players and concepts  are  clearer now,      Hope this helps! <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-exactly-is-a-foundational-model\">What Exactly Is a Foundational Model?<\/h2>\n\n\n\n<p>A foundational model is a powerful, general-purpose system trained on enormous amounts of information, designed to recognize patterns, understand inputs, and generate responses to queries based on the patterns it has learned. It\u2019s the technology behind today\u2019s most advanced AI.<\/p>\n\n\n\n<p>Think of it like the concrete foundation of a house. Once the foundation is solid and strong, builders can construct many different kinds of buildings on top of it \u2014 offices, homes, schools, or shops. In the same way, companies and developers take these foundational models and adapt (\u201cfine-tune\u201d) them to create useful tools like:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chatbots that answer your questions<\/li>\n\n\n\n<li>Apps that generate images from your descriptions<\/li>\n\n\n\n<li>Tools that summarize long documents<\/li>\n\n\n\n<li>Voice assistants that understand different accents and languages<\/li>\n<\/ul>\n\n\n\n<p>While these systems can <em>seem<\/em> like they truly understand what you ask, they are actually recognizing patterns in data and generating responses based on what they\u2019ve learned.<\/p>\n\n\n\n<p>The most famous examples you\u2019ve probably used include ChatGPT (from OpenAI\u2019s GPT series), Google\u2019s Gemini, Anthropic\u2019s Claude, and xAI\u2019s Grok.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Smart Assistant Analogy: <\/h2>\n\n\n\n<p>Imagine a super-smart assistant  who has read millions of books, watched countless videos, listened to hours of conversations, and studied images from all over the world. This assistant isn\u2019t an expert at one single thing \u2014 instead, it has a broad, general understanding of language, ideas, pictures, sounds, and how things work.<\/p>\n\n\n\n<p>With just a little extra guidance, this assistant can write emails, create artwork, explain complicated topics, help with homework, brainstorm business ideas, or even turn your spoken words into text in many languages.<\/p>\n\n\n\n<p>That &#8220;assistant&#8221; is what experts call a <strong>foundational AI model<\/strong> (sometimes also called a frontier model or base model).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-are-there-so-many-models-and-companies\">Why Are There So Many Models and Companies?<\/h2>\n\n\n\n<p>If these models are so powerful, a natural question is: why aren\u2019t we all just using one single AI?<\/p>\n\n\n\n<p>There are a few important reasons:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><td><strong>Reason for Variety<\/strong><\/td><td><strong>Key Details<\/strong><\/td><td><strong>Impact<\/strong><\/td><\/tr><\/thead><tbody><tr><td><strong>Strengths &amp; Specializations<\/strong><\/td><td>Models are often &#8220;tuned&#8221; for specific tasks like coding, creative writing, or high-level reasoning.<\/td><td>You can pick the &#8220;expert&#8221; tool for your specific project.<\/td><\/tr><tr><td><strong>Design &amp; Training Choices<\/strong><\/td><td>Different data sets and safety guardrails lead to unique &#8220;personalities&#8221; and behaviors.<\/td><td>Some models feel more creative, while others feel more cautious or literal.<\/td><\/tr><tr><td><strong>Speed &amp; Cost Tradeoffs<\/strong><\/td><td>Massive models offer deep insights but are slow; smaller models are lightning-fast and cheap.<\/td><td>Businesses can balance high performance with their budget and latency needs.<\/td><\/tr><tr><td><strong>Open vs. Closed Models<\/strong><\/td><td>Proprietary models offer ease of use; open-source models offer customization and privacy.<\/td><td>Users can choose between &#8220;ready-to-use&#8221; services or &#8220;build-your-own&#8221; flexibility.<\/td><\/tr><tr><td><strong>Market Competition<\/strong><\/td><td>Multiple companies (Google, OpenAI, Anthropic, Meta) are racing to innovate.<\/td><td>Rapid improvements in quality, lower prices, and constant new features.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>You can think of it like cars: there\u2019s no single \u201cbest\u201d car for everyone. Some are built for speed, some for efficiency, some for luxury, and some for heavy-duty work. AI models are evolving in a similar way.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-do-these-models-matter-so-much\">Why Do These Models Matter So Much?<\/h2>\n\n\n\n<p>Foundational models are changing everyday life faster than most people realize. Here\u2019s why they\u2019re important \u2014 even if you don\u2019t work in tech:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>They make powerful tools accessible to everyone<\/strong><br>You no longer need to be a computer expert or hire expensive specialists for many tasks. A small business owner can use AI to write marketing emails, design logos, or analyze customer feedback. A student can get help explaining difficult homework. A doctor or teacher can get quick summaries of the latest research.<\/li>\n\n\n\n<li><strong>They save time and boost creativity<\/strong><br>These models handle repetitive or time-consuming work \u2014 drafting reports, editing videos, translating languages, or organizing ideas \u2014 so people can focus on the parts that require human judgment, emotion, and creativity.<\/li>\n\n\n\n<li><strong>They are getting better at working with different types of information<\/strong><br>Newer models don\u2019t just handle text. Many are \u201cmultimodal,\u201d meaning they can work with text, images, audio, and video together. For example, you could describe a scene in words and have the AI create a short video, or upload a photo and ask the AI to explain what\u2019s happening in it.<\/li>\n\n\n\n<li><strong>They drive innovation across industries<\/strong><br>From helping scientists discover new medicines to making customer service faster and friendlier, foundational models are the engine behind many of the helpful AI tools we\u2019re starting to see in 2026.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"whats-new-in-2026\">What\u2019s New in 2026?<\/h2>\n\n\n\n<p>The AI world moves incredibly fast. As of early 2026, here are some of the leading foundational models making headlines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>OpenAI\u2019s GPT-5 series<\/strong> (including newer versions like GPT-5.4): Excellent all-rounders that are especially good at complex tasks, coding assistance, and everyday productivity.<\/li>\n\n\n\n<li><strong>Anthropic\u2019s Claude 4.6<\/strong> (Opus and Sonnet versions): Often praised for careful, thoughtful responses and strong performance in detailed work like writing or analyzing long documents.<\/li>\n\n\n\n<li><strong>Google\u2019s Gemini 3.1 Pro<\/strong>: A standout in handling multiple types of information (text, images, video) and tackling tough reasoning problems.<\/li>\n\n\n\n<li><strong>xAI\u2019s Grok 4<\/strong>: Known for strong reasoning abilities and a more direct, helpful style.<\/li>\n\n\n\n<li><strong>Microsoft\u2019s new MAI models<\/strong>: Specialized ones for turning speech into text quickly, generating custom voices, and creating videos.<\/li>\n\n\n\n<li><strong>Open-source options<\/strong> like Meta\u2019s Llama series, Alibaba\u2019s Qwen, and Chinese models such as Moonshot Kimi: These are freely available for developers to customize and run on their own computers, helping spread AI innovation even further.<\/li>\n<\/ul>\n\n\n\n<p>Many of these models now have huge \u201ccontext windows\u201d \u2014 they can work with very long documents or conversations at once. They also feature \u201cthinking modes\u201d that allow them to spend more time reasoning through complex problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-this-matters-going-forward\">Why This Matters Going Forward<\/h2>\n\n\n\n<p>Foundational AI models are like a new kind of general-purpose technology \u2014 similar to how electricity or the internet changed everything when they became widely available. They aren\u2019t perfect (they can still make mistakes, and humans still need to guide and check their work), but they are becoming incredibly useful partners in work, learning, and creativity.<\/p>\n\n\n\n<p>The exciting part? We\u2019re still in the early days. As these models improve and more people learn how to use them wisely, they have the potential to help solve big problems in healthcare, education, climate science, and daily life.<\/p>\n\n\n\n<p><strong>What do you think?<\/strong> Have you tried any of these AI tools yet? Which tasks would you most like an AI helper for?<\/p>\n\n\n\n<p>Do you want that new \u201cwhy so many models\u201d section to be even simpler (more beginner-friendly), or a bit more technical?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">See Also: <\/h2>\n\n\n\n<p><a href=\"https:\/\/jorgep.com\/blog\/what-are-large-language-models-llm\/\">What Are Large Language Models (LLM) <\/a><\/p>\n\n\n\n<p><\/p>\n\n\n\n<div style=\"font-family: Verdana, Geneva, sans-serif; font-size: 11px;\"><b>Disclaimer<\/b>: \u00a0I work for <a href=\"https:\/\/www.dell.com\/en-us\/work\/learn\/by-service-type-deployment\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Dell Technology Services<\/a> as a Workforce Transformation Solutions Principal.\u00a0 \u00a0 It is my passion to help guide organizations\u00a0through the current technology transition specifically as it relates to <a href=\"https:\/\/www.delltechnologies.com\/en-us\/what-we-do\/workforce-transformation.htm\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Workforce Transformation<\/a>.\u00a0 Visit <a href=\"https:\/\/www.delltechnologies.com\/en-us\/index.htm\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">Dell Technologies<\/a>\u00a0site for more information.\u00a0 Opinions are my own and not the views of my employer.<\/div>\n<div><\/div><br>\n","protected":false},"excerpt":{"rendered":"<p>ALthough not much has changed, I am revisiting this topic ( Original 2024 post: What are LLMS ) as it has been a while, players and concepts are clearer now, Hope this helps!
