Generative AI vs LLM: Understanding the Key Differences

Have you ever encountered these terms and wondered what the difference is? You’re not alone!  Generative AI and LLMs are both hot topics in the world of artificial intelligence. But they tackle specific tasks within the broader field.  In this blog, we’ll break down the key distinctions between generative AI vs LLM, so you can walk away with a clear understanding of what each one does and how they’re revolutionizing different industries.

Generative AI vs LLM: Understanding the Key Differences

What is Generative AI?

Generative AI is like a smart robot that can create new things on its own after learning from lots of examples. It’s like teaching a robot to paint by showing it thousands of paintings; and then it starts creating its own art, even though no one told it exactly what to paint. This robot uses what it has learned to come up with new pictures, stories, or even music that no one has seen or heard before. It’s pretty cool because it can help come up with new ideas or solve problems by thinking outside the box, using what it learned from all the examples it was given.

What are LLMs?

LLMs are like the digital brains behind the AI systems that can read, understand, and generate human-like text. They are built using a type of AI known as deep learning, where a model learns from vast amounts of text data. The key innovation in LLMs is the use of transformer architecture; which helps these models understand the context and relationships in language by processing words in sentences all at once; rather than one after another. This makes them incredibly powerful at tasks like writing articles, translating languages, and even creating code from simple prompts.

LLMs are essentially vast neural networks that have been trained on internet-scale data sources. They can have hundreds of billions of parameters, which are the elements of the model that get adjusted during training to help the model make more accurate predictions. When you interact with an LLM, what you see is the output of this incredibly complex network making predictions on what word comes next, based on the context provided by the input it receives​.

Generative AI vs LLM: What Are The Differences?

Generative AI, LLM both play significant roles in the field of artificial intelligence but serve different purposes and are based on distinct principles. 

Generative AI is a broad term encompassing a variety of AI technologies focused on creating new content across different formats such as text, images, music, and more. It utilizes deep learning and probabilistic modeling to generate diverse and lifelike outputs. For example, Generative AI can be used to create realistic speech, generate new music compositions, or produce photorealistic images. This versatility allows it to cater to creative endeavors across multiple domains, making it a powerful tool for innovation​

On the other hand, LLMs are specialized AI systems designed to understand and generate human-like text. They are trained on extensive text datasets to perform tasks such as language translation, summarization, content generation, and more. LLMs, such as OpenAI’s GPT series, are renowned for their proficiency in these areas, making them invaluable for applications that require advanced language understanding and generation. LLMs excel in processing and generating text-based content, providing sophisticated solutions in natural language processing

Generative AI vs LLM: Scope of Work

The scope of work for generative AI is incredibly vast, as it spans across various media types. For instance, GANs have been used to create photorealistic images, alter facial expressions in videos, and design virtual environments. In the music industry, generative AI models can compose new pieces in specific styles or continue an existing piece coherently.

LLMs, while focused solely on text, have a broad application range within that domain. They’re used in chatbots, content creation, summarization, translation, and more. Their ability to understand and generate language makes them invaluable for any task that involves human-like text processing. Beyond text, LLMs are being extended to multimodal models that can understand a combination of text, images, and sometimes audio; broadening their scope of work to areas traditionally covered by broader generative AI models.

In terms of capabilities, generative AI models are generally evaluated based on the novelty, diversity, and realism of their outputs; whereas LLMs are often assessed based on their understanding of context, coherence, and fluency in generated text, as well as their ability to perform specific language-based tasks such as question-answering or text completion.

Generative AI vs LLM: Training Data

Generative AI

The data used to train generative AI models is highly dependent on the specific application. For image generation tasks, these models might be trained on large datasets of photographs, artworks, or specific types of visual content like faces or landscapes. In the case of music generation, they would be trained on a diverse array of musical pieces across different genres. The key is that the training data must be rich and varied enough to enable the model to learn the underlying distributions of the target domain.

Characteristics of Training Data:

  • Diversity: Training datasets must cover a broad spectrum of examples to ensure the generative model can produce a wide range of outputs.
  • Quality: High-quality, clean data is crucial to train effective models, especially to avoid replicating noise or undesired artifacts in the generated content.
  • Volume: Generative models often require large amounts of data to capture the complexity and variability of the target domain.


LLMs are typically trained on vast corpora of text data sourced from the internet, including websites, books, articles, and more. This enables them to learn a wide range of linguistic patterns, styles, and information.

Characteristics of Training Data:

  • Scale: LLMs are known for being trained on datasets that span billions of words, capturing a wide array of human knowledge and discourse.
  • Diversity: The data includes text from countless domains, genres, and styles, from the highly formal to the colloquial and slang, to ensure the model can understand and generate a wide variety of text.
  • Complexity: Text data encompasses not just the linguistic structure but also the nuances of meaning, context, and cultural references, making it a rich dataset for training.

Generative AI vs LLM: Techniques

Generative AI

Generative AI relies on various techniques, with GANs and VAEs being among the most popular.

  • GANs involve two neural networks: a generator that creates samples and a discriminator that evaluates them against real data, in a kind of cat-and-mouse game, improving each other iteratively. This approach has been highly successful in generating realistic images, music, and even text.
  • VAEs are another technique where an encoder reduces input data to a lower-dimensional space and a decoder reconstructs the output from this space. VAEs are excellent at generating new data that is similar to the training data and are often used in image generation and modification.


  • LLMs use a transformer architecture, which relies on self-attention mechanisms to weigh the influence of different words in a sentence. This enables the model to generate coherent and contextually relevant text over longer passages.
  • Training involves unsupervised learning on a corpus of text, followed by fine-tuning for specific tasks or datasets. The model’s performance improves with the scale, both in terms of the size of the model and the breadth of the training data.

Generative AI vs LLM: Interactivity

The key difference in interactivity between Generative AI and LLMs lies in the nature and depth of engagement. While Generative AI systems can produce amazing outputs in response to specific prompts; their interactivity is often limited to input-output transactions without a deep understanding of context or the ability to engage in back-and-forth dialogue. LLMs, on the other hand, offer a more sophisticated level of interactivity, capable of engaging users in conversations; understanding nuanced instructions, and generating responses that consider the ongoing context and previous exchanges.
