Turn Your Business Knowledge Into
Intelligent AI Applications

Generic AI tools are powerful, but they often lack the context, business knowledge, and integrations required to solve real-world business challenges. A Custom LLM Application connects advanced language models with your proprietary data, systems, and workflows to deliver more relevant and useful AI experiences.

Building a reliable LLM application requires more than connecting an API. It requires the right model strategy, data architecture, retrieval systems, security controls, evaluation frameworks, and infrastructure to ensure the application performs consistently at scale.

MetroMax builds custom LLM solutions designed around your specific business requirements.

Frequently Asked Questions

What is a Custom LLM Application?

A Custom LLM Application is an AI-powered software solution built around a specific business use case. It combines Large Language Models with your business data, documents, workflows, APIs, and systems to deliver context-aware responses, automation, and intelligent user experiences.

Yes. We can build secure applications that connect LLMs with your documents, knowledge bases, databases, and enterprise systems using technologies such as Retrieval-Augmented Generation (RAG), embeddings, vector search, and controlled access mechanisms.

We can work with leading commercial and open-source models, including OpenAI GPT, Claude, Gemini, Llama, Mistral, Cohere, and other models. The right model is selected based on your application requirements, performance expectations, privacy needs, and operating costs.

Retrieval-Augmented Generation, or RAG, allows an LLM to retrieve relevant information from your data sources before generating a response. It is useful when your application needs access to current, proprietary, or domain-specific information without relying entirely on the model’s built-in knowledge.

Yes. We can integrate LLM applications with CRMs, ERPs, Salesforce, databases, document systems, internal APIs, customer platforms, and other third-party applications.

We implement security measures based on the application requirements, including access controls, encryption, secure APIs, data isolation, audit logging, private infrastructure options, and controlled access to enterprise information. .

A focused MVP can typically be developed within a few weeks, while more advanced enterprise applications may take several months depending on the complexity of the data, integrations, workflows, AI capabilities, security requirements, and user experience.
