Gen AI

We connect your knowledge bases, CRM and ERP through RAG pipelines, route each request to the model that suits it, and check every response before it reaches anyone.

Architecture overview · 6 layers

Generative AI architecture

Six layers sit between your data and a response someone can act on. The guardrails layer is what makes the difference between a system you can put in front of customers and one you can only show colleagues.

Layer 01

Enterprise data & context

CRM, ERP, knowledge bases, support tools and event streams feed the pipeline with data that is actually current.

Layer 02

Embedding & vector store

Documents are split at boundaries that keep meaning intact, embedded, and re-indexed whenever the source changes.

Layer 03

RAG & prompt orchestration

The query is matched against the index, the most relevant passages are pulled, and a prompt is built around them.

Layer 04

LLM models & AI services

The assembled prompt goes to whichever model suits that task, judged on the accuracy it needs and what it costs to run.

Layer 05

Guardrails & safety

The answer is checked before anyone sees it. Anything failing a check is held back rather than passed along.

Layer 06

AI-powered outcomes

The validated answer reaches the user, or triggers the next step in a workflow, and the interaction is logged.

Key capabilities

What we build and run

Use case & strategy

We find the use cases worth building, with a feasibility check and ROI mapping against your data and compliance rules.

Data source integration

Pipelines wired into databases, APIs, CRM, ERP, support tools, content platforms and event streams, so models see current data.

Embedding & vector storage

Chunking, embedding and indexing into Pinecone, Weaviate, pgvector, ChromaDB or Milvus, with a re-index strategy that keeps answers current as your content moves.

Prompt engineering & RAG

Retrieval, context assembly and prompt templates on LangChain, LlamaIndex or Semantic Kernel, tuned on your own questions rather than a benchmark.

Model integration

OpenAI, Anthropic, Azure OpenAI, Bedrock, Gemini, Llama and Mistral behind one interface, so a model change is a config edit.

Guardrails & safety

Output validation, PII detection and hallucination checks, with an audit trail that shows why any given answer was allowed through.

Technology stack

Models, stores and orchestration

Multi-model routing keeps the architecture independent of any one of these. Swapping a provider is a configuration change.

Use case · Insurance

Claims and policy analysis, read by a machine first

An insurance provider put claims processing and policy analysis behind a RAG pipeline with fine-tuned models, so assessors review exceptions instead of reading every file.

Frequently asked questions

It depends on the use case, the accuracy you need, how sensitive the data is and what you are willing to spend. We build with multi-model routing, so the choice stays open as prices and capabilities move.

Pick one use case and we will pilot it
