What is an LLM?

A large language model (LLM) is an advanced AI system that processes and generates text. These models form the foundation of various AI applications, including chatbots, virtual assistants, and automated writing tools.

LLMs operate by predicting the next word in a sequence based on the context of preceding words. Trained on extensive text datasets, they learn to identify patterns, grammar, and contextual cues, enabling them to produce coherent and relevant responses. This versatility allows them to handle a wide range of tasks, from answering questions to drafting creative content.

The significant advancement in natural language processing (NLP) brought about by LLMs is their ability to go beyond simple keyword matching. Rather than relying on fixed responses, they generate unique answers by understanding the intricacies of human language. This results in more dynamic and engaging interactions, as the model can adjust its responses according to the user's specific needs.

However, LLMs have their limitations. They are restricted to text-based data and cannot directly interpret other forms of input, such as images or audio. Additionally, while they often produce plausible text, they can sometimes generate inaccurate or irrelevant answers.

In summary, LLMs represent a major leap in AI technology, providing powerful tools for diverse applications. Ongoing research and development are expected to lead to even more sophisticated models, further enhancing the interaction between humans and machines.


What can they be used for?

LLMs are incredibly versatile, capable of adapting to numerous situations and applications. The same core LLM, with some fine-tuning, can perform a wide array of tasks. While their primary function is text generation, the way they are prompted can change the features they seem to possess.

Here are some common uses for LLMs:

  • Translating text between languages
  • Customer service chatbots tailored to specific business documentation and data
  • Answering questions - General-purpose chatbots (like ChatGPT and Google Gemini)
  • Co-pilots or text to code
  • Bug Fixing
  • Creating social media posts, blog entries, and marketing copy
  • Editing and correcting writing
  • Analyzing sentiment
  • Moderating content
  • Answering user comments
  • Performing data analysis
  • Summarize long blocks of text or presentations
  • Prompting text for GenAIs
  • Help with Backlog, Jira task, detailing your pipeline

Even tho it’s just the beginning of the AI revolution, LLMs are very advanced. However there are many tasks that LLMs cannot handle, which require different types of AI models:

  • Generating & Interpreting media (images, videos, audio)
  • Converting files between formats
  • Searching the web

Some LLMs and chatbots may seem to perform these tasks, but they usually rely on additional AI services.

At Kruko, LLMs are one of our specialties, and we have a versatile portfolio of use cases where we fine-tuned existing or used our own models for solutions based on Machine Learning. If your project requires a similar use case, let’s have a quick chat. We can present our portfolio and talk through the technical details. Contact us at
