Build Your Own GPT — Turn Your Expertise into AI Assistants

When Off-the-Shelf Isn’t Enough

Public LLMs like ChatGPT and Claude are incredibly useful — especially for general tasks and open-domain queries. But when your use case involves proprietary content, complex business logic, or domain-specific accuracy, a different approach becomes essential.
Fine-tuned models offer: Higher accuracy on your domain because they’re trained on your data - Full control and privacy as they are hosted where you choose, and are aligned with your compliance needs - Customised behaviour and tone, reflecting your workflows, proprietary expertise, language, and standards - Lower long-term cost at scale, compared to usage based commercial APIs, such as OpenAI.

LLMForge helps you decide whether to fine-tune, prompt-engineer, or combine both — and then gets it done.
72 %

of organizations using generative AI say the biggest challenge is a lack of domain-specific accuracy.

67 %

of European enterprises cite data privacy and regulatory compliance as their top concern when adopting third-party LLMs.

50 %

reduction in inference costs at scale compared to commercial APIs- observed by orgs with fine-tuned open-source models

Fine-tuning or Smart Prompting?

Not sure whether you need a fine-tuned LLM, a pre-trained open-source model, or simply to consume commercial APIs?

We help you assess the trade-offs and choose the most cost-effective, value-driven architecture for your use case.

Your Enterprise. Your Data. Your LLM.

To make generative AI deliver real business value, you need more than just a powerful model. You need alignment.
Alignment with your data, your workflows, your compliance rules, your goals, and your proprietary knowledge and expertise.

With LLMForge services, REVARTIS Teams work with you to take control at every layer, from curating internal expertise, to fine-tuning open models, to deploying AI assistants tailored to your organisation, while respecting your security, compliance, and sovereignty requirements.

Whether you’re a consultant building your own GPT, or a company enabling internal teams with private and specialised assistants, we help you forge AI that works for you, securely, efficiently, and with full ownership of your assets.

FAQ

Frequently Asked Questions

LLMForge offers three tiers to match your AI maturity and needs:

  • Starter: Build your first assistant using your content and smart prompts, powered by RAG — no model training required.
  • Sprint: Fine-tune an open-source model on your proprietary data for higher accuracy and domain alignment.
  • Xpert: Full-stack solution combining fine-tuning, RAG, private hosting, and compliance-by-design — ideal for regulated and high-stakes use cases.

We help you choose the best fit based on your function, risk level, and impact goals.

RAG (Retrieval-Augmented Generation) connects your documents to a model in real time — ideal for question-answering and document-heavy use cases.

Fine-tuning is best when you need a pre-trained large language model (LLM) to deeply understand your domain, follow complex logic, or adopt your tone and style.

Most Xpert clients use a hybrid approach: fine-tuned models enhanced with RAG pipelines for real-time accuracy.

We support a wide range of structured and unstructured content:

  • PDFs, Word docs, slides, knowledge bases
  • Process documentation, contracts, transcripts
  • Internal policies, FAQ repositories, guides
  • CRM data or other systems’ data, meeting notes, spreadsheets (with structure)

We assist with data preparation and ensure your content is clean, relevant, and AI-ready.

Yes. With LLMForge Xpert, you can choose:

  • On-premise deployment
  • Sovereign cloud providers (e.g., Swiss or EU-based)
  • Private VPC hosting on trusted platforms

We help you select and implement the right infrastructure based on your IT, security, and compliance needs.

Absolutely. Data privacy and sovereignty are central to our approach:

  • Your data is never used to train third-party models
  • You retain full control over hosting and storage
  • All models and pipelines are deployed under your governance
  • We follow GDPR and help align with internal security standards

With Xpert, we also support access controls, auditability, and model governance frameworks.

We work with trusted open-source and licensed models, including, for example:

  • Mistral, LLaMA 2/3, Falcon, Gemma
  • Mixtral, Zephyr, Phi, and others
  • Custom APIs or hosted models where appropriate

We help you choose the best base model based on performance, licensing, use case, and infrastructure compatibility. With Xpert, we also offer inter-model and intra-model (different sizes) benchmarking.

Yes. We specialize in multilingual deployments and support fine-tuning or RAG-based assistants in multiple languages — including low-resource languages not supported by major commercial APIs.

This is especially valuable for global teams, public organizations, and HR, legal, or customer-facing functions.

Typical (average) delivery timelines:

  • Starter: 1–2 weeks (RAG assistant based on your documents)
  • Sprint: 3–5 weeks (data prep + fine-tuning + deployment)
  • Xpert: 6–8 weeks (end-to-end delivery with full infrastructure and compliance support)

You get measurable outcomes in weeks, not months.

It is important to note that data readiness might shorten or substantially extend delivery times.

Yes. We offer:

  • Web-based chatbot widgets
  • Custom UI for internal use
  • REST API endpoints for integration into portals, apps, or SaaS platforms

Whether you’re an enterprise, a public institution, or a product team, we ensure your assistant fits into your environment.

Every LLMForge tier includes:

  • 🎯 Use case design workshop to align the assistant with your business goals
  • 🧹 Data preparation support to clean, structure, and format your content
  • ⚙️ Model configuration — via prompt design, RAG pipeline, or fine-tuning
  • 🧪 Testing, evaluation, and deployment to ensure accuracy and performance
  • 📄 Documentation and handover so you fully own the result

LLMForge Xpert includes advanced services such as:

  • 🧠 Multi-agent setup across functions or use cases
  • 🏛️ Private or sovereign infrastructure deployment
  • ✅ Compliance integration with your internal policies
  • 🔁 Long-term governance planning (access control, monitoring, re-training workflows)

Our clients always retain the ability to fully maintain and re-fine-tune their models in-house.
That said, REVARTIS remains available to assist, advise, or scale capacity whenever needed — from quick support to strategic upgrades.
