Cast AI is a platform designed to optimize cloud-native environments for AI and large language model (LLM) workloads by automating resource management and reducing operational costs. It enhances efficiency through features like GPU autoscaling, smart bin-packing, GPU sharing, and an AI Enabler that dynamically selects the most cost-effective LLMs for each task. By integrating seamlessly with Kubernetes, Cast AI helps manage the complexities of cloud infrastructure, ensuring clusters are right-sized, high-performing, and cost-effective. This approach allows companies like Fairgen to optimize their resource utilization and reduce costs by up to 70% without sacrificing performance or user experience. The platform's comprehensive cost monitoring tools and automated LLM cost optimization make it easier for businesses to integrate AI into applications, leveraging collaborations like the one with Hugging Face to further streamline deployment on optimized Kubernetes clusters.
