What Are Large Language Models (LLMs)?

A nagy nyelvi modellek (Large Language Models, LLM-ek) olyan mesterségesintelligencia-modellek, amelyeket az emberi nyelv megértésére, feldolgozására és generálására fejlesztettek ki. Képesek szövegek elemzésére, kérdések megválaszolására, tartalmak létrehozására és összefoglalására, információk kinyerésére, adatok kategorizálására, valamint természetes nyelvű interakciók támogatására a szoftveralkalmazásokban.

A vállalkozások számára az LLM-ek meglévő rendszerekbe integrálhatók, vagy egyedi AI-alkalmazások alapjául szolgálhatnak. Ez lehetővé teszi a nyelvi feladatok automatizálását, a szoftverekkel való felhasználói interakciók fejlesztését, valamint új, mesterséges intelligenciára épülő funkciók kialakítását a konkrét üzleti igényeknek megfelelően.

When Does Your Business Need an LLM Solution?

An LLM solution can be valuable when a significant part of your business processes involves understanding, creating or processing language. Tasks that require employees to repeatedly read, write, summarise, classify or extract information from text can often be supported or partially automated with large language models.

Custom LLM solutions can also add natural-language capabilities to existing software, helping users interact with complex systems and information in a simpler and more intuitive way.

Your Team Handles Large Volumes of Text

Employees regularly need to review, summarise, categorise or extract information from emails, documents, reports and other text-heavy content.

Repetitive Language Tasks Take Too Much Time

Teams repeatedly create similar responses, summaries, descriptions or other written content that could be supported by an LLM-powered workflow.

Your Software Needs Natural-Language Capabilities

You want users to interact with your application through natural language instead of relying only on traditional menus, forms or search functions.

You Want to Add AI Capabilities to Existing Software

Your existing product or business system could benefit from features such as text generation, summarisation, classification, information extraction or conversational interactions.

What Business Problems Can LLMs Solve?

Time-Consuming Text Processing

LLMs can help analyse, summarise and organise large volumes of emails, reports, documents and other text-based information.

Repetitive Content Creation

Businesses can use LLMs to support the creation of recurring content such as responses, descriptions, summaries and other business communications.

Manual Information Extraction

LLMs can identify and extract relevant information from unstructured text, reducing the need for employees to review documents manually.

Complex Text Classification

LLMs can categorise, label and route text-based information based on its meaning and context rather than relying only on predefined keywords.

Limited Natural-Language Interaction

LLMs can add conversational and natural-language capabilities to software, making it easier for users to interact with applications and complete tasks.

Difficult-to-Scale Language-Based Workflows

Processes that depend heavily on reading, writing or interpreting text can become difficult to scale manually. LLM-powered workflows can support teams as the volume of language-based work increases.

Frequently Asked Questions

Let's Talk

LLM development services involve designing, building, integrating and optimising software applications powered by large language models. These services can include custom LLM applications, model and API integration, prompt and workflow development, evaluation, testing and production deployment.

Large language models can support business tasks that involve understanding, processing or generating language. Common applications include text generation, summarisation, information extraction, classification, conversational interfaces, document processing and AI-powered features within existing software.

An LLM is a type of AI model designed primarily to understand and generate language, while generative AI is the broader category of AI technologies that create new content such as text, images, audio, video or code. LLMs are therefore one of the technologies used to build generative AI applications.

Yes. LLM integration services can add language-model capabilities to existing web applications, mobile applications, internal platforms and business software. Depending on the use case, this can include text generation, summarisation, classification, information extraction or natural-language interfaces.

Not necessarily. Many business applications can be built using existing models and APIs, with the surrounding software, prompts, workflows and integrations customised for the specific use case. Training or fine-tuning a model may be considered when the requirements justify it, but it is not necessary for every LLM application.

LLM development is the broader process of building applications that use large language models. RAG development is a more specific approach that enables an LLM application to retrieve relevant information from external sources, such as company documents or knowledge bases, before generating a response.

The right model depends on factors such as the use case, required output quality, response speed, context requirements, integration environment, privacy considerations and operating costs. An LLM development company should evaluate these requirements rather than automatically using the same model for every application.

LLM applications should be tested using realistic inputs and clearly defined evaluation criteria. Testing can assess output quality, consistency, instruction following, error handling, performance and how the application behaves in edge cases before it is deployed to users.

The security of an LLM application depends on its architecture, model provider, integrations and how data is handled. Production systems should consider access controls, sensitive-data handling, API security, logging and the information that is sent to external model providers as part of the overall application design.

The development timeline depends on the complexity of the use case, required integrations, application functionality and testing requirements. A focused LLM feature or prototype can require substantially less development than a complex production system with multiple integrations, workflows and security requirements.
