What Is a Serverless API Platform?
A serverless API platform enables developers to deploy and run AI models without managing underlying infrastructure. These platforms automatically handle scaling, resource allocation, and performance optimization, allowing teams to focus on building applications rather than managing servers. Serverless inference platforms are particularly valuable for AI workloads with variable traffic patterns, as they offer pay-per-use pricing, automatic scaling, and simplified deployment workflows. This approach is widely adopted by developers, data scientists, and enterprises to deploy language models, multimodal AI systems, and inference endpoints for applications ranging from chatbots to content generation and real-time analytics.
