# Entry
Over the past few years, Immense language models (LLM) They became almost bitter heroes in the AI landscape and media channels-sometimes advertised as everything in one problem. This may be a compact exaggeration on my part. It is true, however, that LLM is increasingly perceived by many as necessary tools in the enormous majority of applications in the real world that require AI systems or data -based systems.
This article aims to restore the conversation about LLM back to Earth. We will not only examine a wide range of operate cases in which LLM can add real value, but also the restrictions with which they face. Understanding these boundaries is crucial, because not every challenge is best solved with LLM, and in some scenarios, using them can even introduce unnecessary risk or complexity.
# The best cases of operate in which LLM adds original value
LLM is a masterpiece of natural language processing (NLP) designed to achieve benefits in terms of language understanding and language generation tasks. The diagram below contains some of the most common tasks of understanding and generating language, placing each task under the basic (but not necessarily the only one) type of “language skills” needed to take. For example, a summary or translation of the text is usually associated with a great understanding of the language, but ultimately also requires the possibility of generating a language to generate the output data: a summarized or translated version of the original input text.

While these tasks include the most common cases of operate for LLM, so far the discussion was abstract. Let us examine some of the actual situations in which LLM are the right tool for the task, emphasizing the specific understanding of the language and/or task of the generation involved in:
LLM is a masterpiece of natural language processing (NLP) designed to achieve benefits in terms of language understanding and language generation tasks.
// Automated customer service
This is a case of high popularity in sectors such as retail and e-commerce, in which LLM can have a immense impact. Texts such as customer reviews or queries sent by the Internet form can be analyzed by LLM to understand and classify the user’s intentions (recognition, complaint, request, etc.), generate appropriate answers and answer customer questions. These specific tasks, especially the last about answering questions, are best solved by building a virtual assistant based on LLM, which is able to understand and react to a wide range of questions of customers expressed in natural language.
// Summary of documents
In areas such as law, scientific research and to some extent journalism can be useful in condensing long and elaborate text documents, such as articles and reports in concise and legible summaries including key observations and facts. Although this operate of LLM can significantly raise the efficiency of tedious operate cases, such as a review of scientific literature, it is vital not to rely completely on the summaries generated by LLM, as well as manually checking the sources considered the most vital in order to continue diving in specific aspects or details.
// Multilingual communication
Used for LLM translation are a great tool that allows cross understanding. They are useful for managing customer opinions at e-commerce, which operates in many countries, providing personalized support and supporting content in several languages in general. In the case of proper training in the field of sufficient and various data, LLM may also support interpret a possible local slang or phrases that may not be understood at first glance.
// Semantic search and answering questions
When LLM is integrated with recovery generation systems that can achieve a deeper understanding of the user’s inquiry, they can be used with great effectiveness to answer the elaborate, open questions about databases or documents, ensuring direct and contextual reactions.
// Generating inventive text
Finally, LLMs have amazing inventive possibilities to generate text of different style, structure and intentions. From precise and attractive product descriptions and narrative content with solid fluidity and tone, to captivating poems in many different styles, LLM can create a wide range of inventive text.
# When to operate something else? LLMS restrictions
Despite their great ability to deal with a variety of language understanding and language generation, which can often be very arduous, it is not realistic recognition of them as a comprehensive solution for all types of problem. Many operate cases that have been historically resolved using time-honored machine learning solutions like building a predictive system for classification, regression and forecasting-are still the best solved by building specific machine learning models that learn based on the domain specific data to perform the target predictive task.
Other specific tasks traditionally solved by AI of earlier generations, such as systems based on rules or logical reasoning models, are still best solved by such time-honored approaches in some cases: low delay decision tasks and reasoning tasks limiting the facts are a good example of this.
Below is a concise list of operate cases in which LLM capabilities are narrow, emphasizing the right alternative approach to application:

# Summary and packaging
LLMS stand out in scenarios that requires inventive text generation, extracting key elaborate information from unstructured text sequences and using the applications of conversation assistants. However, their effectiveness is narrow for predictive scenarios requiring high precision, performance in real time, logical logical reasoning specific to the domain or access to specific, reserved data.
