Almost 80% of companies consider artificial intelligence (AI) the top priority in their strategic decisions. However, the most significant challenges that companies face when implementing AI and machine learning solutions involve measuring AI’s value, skills shortages, and infrastructure incompatibility. These challenges complicate AI model deployment, as organizations cannot evaluate the long-term monetary benefits, find staff with relevant digital expertise, and raise funds to upgrade infrastructure for seamless integration. One viable solution is to find appropriate third-party vendors offering cost-effective artificial intelligence as a service (AIaaS) platforms to mitigate these issues. Businesses can significantly benefit from the vendor’s experience in the industry and quickly understand where and when to use AI to remove operational inefficiencies. In this article, we will discuss the types of AIaaS, their benefits and challenges, and factors to consider when choosing the best AIaaS platform. We will also list the top AIaaS providers in the market. Types of AI as a Service Multiple AIaaS platforms offer companies different AI tools to meet their business needs. Categorizing these AI tools according to their type helps determine the most appropriate solution to achieve a particular objective. Bots As natural language processing (NLP) and generative AI (Gen AI) algorithms become crucial to organizational success, technology leaders increasingly rely on intelligent bots to automate business operations and enhance the customer experience. Bots are conversational AI software that uses advanced deep learning models to help users perform multiple tasks through a human-like interface. While chatbots are the most common framework, virtual assistants and AI Agents are also emerging as more modern forms of bots.  The following gives an overview of these three technologies to help understand their differences. Chatbots: Chatbots are simple AI-powered programs that use text or voice to understand user queries and generate relevant responses. For instance, chatbots on e-commerce websites provide customer support by helping users find the item they are searching for. Virtual Assistants: Virtual assistants use more advanced machine-learning models to understand the surrounding context from text and voice inputs. They offer personalized assistance to help users perform their daily chores. Alexa is an excellent example of a virtual assistant that helps people schedule tasks, set reminders, and manage smart home devices. AI Agents: AI Agents are autonomous programs that perform tasks according to user specifications. These tasks can involve monitoring particular metrics and generation recommendations, executing pipelines, and automating operational workflows like sending or responding to emails. Devin, for instance, is an advanced AI software engineer who writes code based on user requirements without manual intervention. Machine Learning Frameworks Providers of AI as a service sell multiple solutions to help users quickly build and deploy AI applications. These frameworks have AI functionalities that streamline model development, deployment, and monitoring. Google Cloud AI is a good example, offering multiple AI services to summarize large documents, deploy ML image processing pipelines, and help create chat apps with retrieval augmented generation (RAG). Application Programming Interfaces (APIs) APIs allow users to connect different systems for shared communication and help build an integrated platform to perform specific tasks. AIaaS providers offer APIs that let users create complex end-to-end solutions with AI capabilities that integrate seamlessly with existing tech infrastructure. The Open AI API is a good example, as it allows users to integrate state-of-the-art generative pre-trained transformer (GPT) models into custom AI applications. Data Labeling Data labeling is a crucial process in AI development that involves annotating data points to create accurate, relevant, and consistent datasets to train AI models. AIaaS platforms offering data labeling services include pre-built models that understand input data to automatically label items and check label quality, speeding up the annotation process. Popular AI-based data labeling platforms include Encord, LabelBox, and Amazon SageMaker Ground Truth. Benefits and Challenges of AI as a Service Like Software-as-a-Service (SaaS), AIaaS allows users to have better accessibility to AI for building complex AI technologies. But, how to determine if your use case requires AIaaS solution? One practical way is to understand the benefits and challenges AIaaS involves. Below are the most significant benefits and challenges associated with AIaaS. Benefits The primary benefits that AIaaS offers include scalability, productivity gains, enhanced automation, and cost-effectiveness. Scalability AIaaS allows users to scale their operations according to demand quickly. It significantly benefits small businesses that can upgrade their AIaaS plans instead of building in-house AI solutions. For instance, a startup running a chatbot on an e-commerce site can subscribe to higher-tier packages to handle increasing customer queries. Productivity Gains AIaaS platforms allow technical staff to identify and resolve issues more efficiently, leading to better decision-making and increased productivity gains. For instance, AI-based data labeling platforms compute relevant quality metrics that indicate where the issue lies. It helps annotators and reviewers fix labeling errors quickly with minimal effort. AIaaS solutions can also include forecasting models that can predict key performance metrics to allow for more proactive action. According to McKinsey, combining such AI platforms with other technologies can boost productivity by 3.4 percent annually. Enhanced Automation AIaaS lets you quickly automate routine tasks through AI agents and easy-to-use APIs that can seamlessly integrate with your existing AI infrastructure. For instance, AIaaS platforms can help businesses build real-time pipelines to perform data pre-processing tasks on extensive datasets. The platforms can also flag issues and allow users to focus on finding efficient solutions. Cost Effectiveness AIaaS is more cost-effective than in-house AI systems as businesses do not have to manage the infrastructure themselves. For instance, a business wanting to build its proprietary AI solution must bear the costs of staff recruitment and compatible hardware and software while ensuring proper employee training. In contrast, businesses can quickly integrate AIaaS platforms into their existing system or use cloud computing for more optimal performance. Additionally, AIaaS providers will perform maintenance and upgrade procedures so users can allocate their resources to more relevant tasks. Challenges Although AIaaS allows businesses to use cutting-edge technology to optimize workflows, a few issues make choosing the right AIaaS provider challenging. Data Privacy Issues AI applications involve a significant amount of sensitive customer data to perform efficiently. However, businesses using AIaaS platforms run the risk of exposing their data sources to the AIaaS provider, who has access to all sensitive information. Recent reports show that 93% of organizations suffered two or more identity-related breaches in 2023. The situation can lead to data breaches, causing the business to incur heavy losses. For instance, weak vendor security protocols can lead to data leaks, which can significantly reduce customer confidence and cause a loss of market. Businesses must verify data privacy procedures and compliance certifications the vendor follows to avoid such incidents. Vendor Lock-in Changing vendors can be costly as migrating from one platform to another involves staff retraining, time spent discussing requirements, and possible downtime that disrupts daily business operations. A recent survey shows that around 47% of businesses cited vendor lock-in as a significant concern. Organizations can avoid vendor lock-in issues by assessing the vendor’s market experience, customer reviews, and commitment to meeting the organization’s strategic goals in the long term. Less Customizability AIaaS platforms often lack customization options, as users cannot access the low-level code of AI algorithms. The problem worsens for businesses that operate in dynamic environments and require frequent feature changes and upgrades. For instance, a business analyzing user reviews may find that a generic sentiment analysis model on an AIaaS platform performs poorly on a customer group in a different geographical location. The reason could be their different language or expressions to provide feedback. A hybrid approach combining AIaaS models with in-house custom solutions can help mitigate these issues. Constant collaboration with vendors can also help them understand your changing needs. Skills and Knowledge Gap Although AIaaS providers manage the backend infrastructure, users still need AI expertise to use the platform to its full potential. However, finding the right talent is challenging as AI technology evolves rapidly. A survey reports that 48% of tech leaders say the lack of appropriate staff with relevant AI expertise is the most significant roadblock in AI implementation. A possible solution includes choosing vendors with dedicated support staff who can help users become familiar with all the platform's features. Businesses can also conduct regular training to help build technical acumen as new AI technologies emerge. Choosing the Best AIaaS Platform The above-mentioned benefits and challenges give you a reasonable starting point for understanding how to choose a suitable AIaaS platform.
