Hosting Large Language Models

OpenAI, Azure, and Going Self-Hosted

Large Language Models (LLMs) like OpenAI's GPT series have become central to driving AI strategies in business. However, deciding how to host these powerful tools can be as crucial as the models themselves. From cloud-based services to self-hosting options, the choice impacts everything from performance to privacy. In this context, we also explore how World of Workflows serves as a versatile platform that can facilitate all three hosting options.

OpenAI: Effortless Integration in the Cloud

OpenAI offers a cloud-based platform that provides businesses with access to state-of-the-art LLMs without the overhead of managing physical infrastructure. This service is ideal for businesses that want to scale their AI capabilities rapidly and flexibly. With OpenAI's cloud service, you get a ready-made, robust AI power without worrying about maintenance, updates, or scaling issues.

Advantages of OpenAI's Cloud Service:

  • Ease of Use: Quick setup and integration into existing workflows.

  • Scalability: Effortlessly scale up or down based on your business needs.

  • Zero Maintenance: No need to worry about the underlying infrastructure or keeping the system updated.

Azure OpenAI: Seamless Service on a Trusted Platform

In collaboration with OpenAI, Microsoft Azure offers an enterprise-grade version of the same LLMs within its cloud ecosystem. Azure OpenAI is particularly appealing to businesses that are already leveraging Azure's cloud services. It allows for tight integration with other Azure offerings, providing a cohesive and secure environment for AI-powered applications.

Why Azure OpenAI Stands Out:

  • Integrated Environment: Easy integration with existing Azure services and tools.

  • Enterprise Readiness: Enhanced security and compliance features suitable for enterprise needs.

  • Customisation: Offers more control over the AI models and their deployment.

Self-Hosted Models: The Ultimate in Customisation and Control

Some businesses may choose to host LLMs on their infrastructure. This approach can be driven by the need for customisation, data privacy, stringent compliance requirements, or a desire for full control over the AI infrastructure.

Self-hosting allows businesses to:

  • Tailor AI Models: Modify the model architecture to fit specific business needs.

  • Manage Data Sovereignty: Keep sensitive data within the company's own data centers.

  • Comply with Regulations: Adhere to specific industry or government regulations that mandate data and processing to remain on-premises.

Tools and Frameworks for Self-Hosting:

Several tools and frameworks facilitate self-hosting of LLMs, including:

  • Machine Learning Frameworks: TensorFlow, PyTorch, and others that can support the training and deployment of LLMs.

  • Containerisation: Docker and Kubernetes can package LLMs for consistent deployment across various environments.

  • Infrastructure as Code: Tools like Terraform and Ansible can help automate the setup and management of the hosting environment.

World of Workflows: Bridging Hosting Options

World of Workflows emerges as a versatile platform that can navigate businesses through the complexities of hosting LLMs. Whether you choose the managed services of OpenAI, the integrated solutions of Azure OpenAI, or the bespoke route of self-hosting, World of Workflows can streamline the process.

With World of Workflows, businesses can:

  • Connect with Cloud Services: Integrate with OpenAI or Azure OpenAI's APIs through a user-friendly interface.

  • Orchestrate Self-Hosted Solutions: Manage and deploy self-hosted LLMs, ensuring they work harmoniously with other business systems.

  • Maintain Flexibility: Move between different hosting options as business needs and strategies evolve, without being locked into a single approach.


The hosting of LLMs is a strategic decision that can influence the efficiency, privacy, and scalability of AI initiatives. While cloud services like OpenAI and Azure OpenAI provide convenience and integration, self-hosted solutions offer customisation and control. Tools like World of Workflows ensure that regardless of the chosen path, the process remains streamlined, secure, and adaptable to changing business requirements. As LLMs continue to shape the future of business, the hosting conversation will only become more nuanced and critical to success.
