Generative AI Suite with LLMs — architecture overview

01 — The problem

Teams wanted to use LLMs for real work, but raw chat interfaces gave inconsistent results and no way to plug in company knowledge or house style.

02 — Our solution

Purpose-built tools, each with its own prompt pipeline, retrieval over the right data and a simple interface — so a marketer or analyst gets a reliable result without prompt engineering.

Architecture

How it works

The pipeline, step by step — from the first input to the final output.

  1. 01

    Inputs

    Documents, briefs and knowledge bases are ingested and embedded into a vector store.

  2. 02

    Pipelines

    LangChain pipelines combine retrieval, templates and model calls per tool.

  3. 03

    Models

    GPT-4o for quality-critical steps, open HuggingFace models where cost matters.

  4. 04

    Dashboards

    Simple web UIs with history, re-generation and export.
