CUSTOM IMPLEMENTATIONS

Customized LLMs tuned for your specific data and business needs


Customized LLMs tuned for your data and business needs

For the vast majority of use cases, organizations need custom LLMs tuned for their data and specific security & performance needs.

We've found that expertise in selecting & customizing the right LLM architectures for each unique use case is crucial for value creation.


This tailored approach surpasses generic one-size-fits-all platform solutions, giving your business a competitive edge.


Additionally, it ensures that your business retains full control over its AI strategy; allowing for forward-looking adaptability in the ever-evolving AI landscape to achieve sustainable growth over the long-term.

Technology agnosticism and cloud & on-prem deployments

Depending on security and privacy needs, companies need transparent and flexible AI architectures and technologies for both cloud & on-prem. We acknowledge that there are use cases for both closed cloud API LLMs, internally hosted open source models and mixtures of both.


We are technology agnostic and support our clients in strategic decision-making and implementations with a modular approach.


We help companies extract the maximum value from existing LLM architectures - while maintaining flexibility as new technology paradigms arrive. Change is the only constant, which is incorporated in our way of working.

RAG & Fine-Tuning

Retrieval-Augmented Generation architectures are the backbone of building customized LLMs tuned for your data. We utilize carefully crafted RAG pipelines, which can also be combined with model fine-tuning for increased accuracy.

Knowledge Base Extraction

Knowledge Extraction

If you can do the hard work of extracting data from internal documents and tables, you'll have an edge. We have developed a novel vision-based method to do exactly this and extract data from e.g. pdf's for customized LLMs.

Custom Integrations

We believe that integrations to leading systems of record and engagement are crucial. We support out-of-the-box integrations for the most popular systems, while building custom integrations based on client requirements.
