Market Summary

• The market has gained significant traction in the corporate world, driven by the escalating enterprise demand for productivity and automation. This model, which is characterized by the use of proprietary, internally developed machine learning models, is increasingly being adopted for domain-specific applications. The rise of verticalization, where organizations focus on developing models tailored to their unique industries and business processes, is a key trend fueling this market's growth. Despite the potential benefits, the market presents challenges. One of the most significant hurdles is the unpredictable total cost of ownership. Developing and maintaining these models in-house requires substantial investment in hardware, software, and human resources.
• Furthermore, the lack of transparency in the model development process can lead to challenges in explaining model decisions and ensuring compliance with regulatory requirements. A real-world business scenario illustrating the potential of closed-source foundation models is in the realm of supply chain optimization. A manufacturing company, for instance, might develop a proprietary machine learning model to predict demand for its products, optimize inventory levels, and improve delivery times. By keeping the model in-house, the company can maintain control over its intellectual property and customize the model to its specific business needs. However, the company must also invest in the necessary resources to develop, train, and maintain the model, as well as ensure regulatory compliance.
