Summary

OneAdvanced, a UK software provider, built a UK-sovereign AI platform by self-hosting Llama 4 Maverick and Llama Guard 4 on Amazon SageMaker AI. This platform utilizes a RAG pipeline on pgvector and over 50 agents developed with Strands Agents SDK on Amazon ECS.

OneAdvanced, a prominent UK enterprise software provider, has successfully implemented a robust, UK-sovereign AI platform. This initiative involved self-hosting advanced large language models, Llama 4 Maverick and Llama Guard 4, within the Amazon SageMaker AI environment. The deployment ensures data residency and compliance with UK regulations. The platform's architecture includes a Retrieval Augmented Generation (RAG) pipeline, leveraging pgvector for efficient data retrieval. Furthermore, it integrates over 50 AI agents, developed using the Strands Agents SDK, running on Amazon ECS. This comprehensive setup demonstrates a practical application of advanced AI technologies in a regulated, enterprise context.

Why it matters

Professionals can learn from this case study about deploying sophisticated AI agents and LLMs in a sovereign cloud environment, addressing data residency and compliance needs. It showcases a blueprint for building secure, scalable AI infrastructure.

How to implement this in your domain

  1. 1Evaluate cloud provider options for sovereign data requirements.
  2. 2Select appropriate LLMs for self-hosting based on performance and licensing.
  3. 3Design a RAG pipeline using vector databases like pgvector for enhanced context.
  4. 4Develop and deploy AI agents using an SDK on container orchestration services.
  5. 5Implement robust security and compliance measures for regulated data.
