Essential features
Get started in minutes
Customizable
Every company ticks a little differently. With the c4 GenAI Suite, wizards, data sources and interfaces can be easily adapted to your processes.
The interface can be adapted to the company CI via the admin frontend.
Further integration is also possible, and we are of course happy to help with this.

SSO login
The system can be integrated into the company IT system via SSO login. Authorizations can be assigned via users and groups.
Full control over data & models
All databases, vector stores and LLM endpoints are in your hands. Whether Azure OpenAI, Ollama or a fine-tuned model on your own GPU – you decide which bits leave your data center.
From on-prem full privacy to cloud native
Whether closed corporate networks with strict compliance requirements or scalable Kubernetes clusters in the public cloud – the c4 GenAI Suite runs wherever you need it. It can also be set up on local hardware with open source LLMs and NVIDIA Enterprise AI Stack.
The c4 GenAI Suite is publicly available as open source.

RAG with file upload, extraction, vectorization and semantic search
RAG (Retrieval-Augmented Generation) combines semantic search with generative LLMs to produce more precise and factually correct answers.
The process involves several steps:
First, documents are fed into the system via file upload, then relevant information is extracted, followed by vectorization of the content for the semantic search. Relevant documents are then identified in a query and embedded as context in the AI-generated response. Our implementation follows current best practices for building efficient RAG pipelines.
Plug-and-play RAG:
The REIS server implements RAG best practices and handles the complete RAG pipeline for you: Simply select bucket, activate extension and your context-aware chatbot can be built. Rights and visibility can be controlled via groups and assistants.

AI-agent-supported workflows
With frameworks such as n8n, powerful agents can be integrated into individual workflows.
Universal interface MCP
The c4 GenAI Suite connects effortlessly with your daily work tools and systems thanks to the standardized MCP interface. This gives you direct access to important information sources and collaboration platforms.
Whether knowledge databases, document storage or team communication – integrate your favorite tools such as Confluence, Google Drive and Slack and use the full power of your data.

Quality assurance through LLM-Eval
Quality is often underestimated in GenAI projects. With LLM-Eval, we carry out automated Q&A tests, measure relevance, factual accuracy and hallucinations – and thus keep a constant eye on the quality of the answers. This enables continuous improvement.
The c4 GenAI Suite is available as open source. Discover the source code on GitHub and see for yourself the wide range of possible applications.

Ralf Brauchler
I would be happy to show you in a demo how the c4 GenAI Suite is structured and how you can use it for your needs.
AI strategy & use case discovery
We dig deep into your business processes and data landscape and identify high-value scenarios together. From this, we develop a roadmap that aligns benefits, strategic added value and feasibility.
First, we review existing data sources, talk to your experts and analyze the regulatory framework. We prioritize ideas that deliver measurable impact and contribute to the company's goals. Together, we define specific success criteria and develop an iterative implementation model.
This results in a clear roadmap that takes into account both quick wins and long-term scalability and brings all relevant stakeholders on board.
Your result of the AI strategy and use case discovery:
Rapid prototyping
Within a few days, a clickable proof of concept is created that uses real content and delivers tangible results to stakeholders. Early feedback minimizes risks and accelerates decision-making.
We rely on lightweight, reusable components of the c4 GenAI Suite and integrate your most important data sources. You can see live how chatbots, RAG search or evaluation metrics work in your context.
This gives you a realistic impression of performance, usability and added value before large budgets are allocated. At the same time, the prototype creates internal awareness, facilitates budget approvals and lays the foundation for a seamless transition to production development.
Your result of rapid prototyping:
Productive development
We turn the prototype into a robust production solution that runs smoothly under full load in real user scenarios and integrates seamlessly into your existing IT landscape.
We address scalability, performance, security and maintainability, set up automated quality checks and regulated deployment workflows and establish role and release processes.
Together with your teams, we define clear release cycles, monitoring metrics and escalation paths to ensure that operations and further development run smoothly. Regular security and compliance updates ensure that sensitive data is protected at all times. Comprehensive documentation, training and knowledge transfer ensure that you can maintain or expand the solution independently at any time.
Your result of the productive development:
Integration & operation
We link the suite with your existing specialist and IT systems, whether ERP, CRM, data warehouse or identity service.
We ensure that data flows securely, access rights are mapped correctly and the application integrates seamlessly into your processes. Automated deployment processes enable predictable releases without downtime, while continuous monitoring creates transparency regarding usage and performance.
On request, we can take over full operation – around the clock, in your infrastructure or in a cloud environment managed by us.
Your result with integration & operation:
Maintenance contracts
SLA-supported maintenance contracts give you planning security:
Our team monitors availability, applies security patches as well as model and framework updates and is available as a single point of contact for incidents – by phone or via your ticket system.
We analyze logs and evaluation metrics, suggest optimizations and roll out new features according to coordinated change windows. Clearly defined response and recovery times, regular health checks and a dedicated customer success lead ensure that your GenAI solution remains performant, secure and audit-ready.
Your result with our maintenance contract:
Quality assurance with LLM-Eval
Quality is often underestimated in GenAI projects. With LLM-Eval, we validate your chatbot before it gets into the hands of users – and then on an ongoing basis.
Your own documents are used to create realistic question-and-answer catalogs against which the model is regularly tested. We evaluate how accurate, correct and true to the source the answers are, detect hallucinations at an early stage and set clear thresholds for when adjustments are made.
Trend dashboards show whether model updates are bringing real progress or threatening a drop in quality.
