AI as a Service (AIaaS) refers to cloud-based services that provide organizations with access to pre-built or customizable AI models and infrastructure. These services allow businesses to host and run AI models, often with the ability to tailor them to meet their specific needs. AIaaS enables customers to leverage AI capabilities without needing to build the underlying infrastructure or develop complex AI models from scratch.
