Summary

Nikhil Madan, Vice President of AI Infrastructure at TuringData, presented at SuperAI Singapore 2026, arguing that the traditional "more GPUs, better models" approach to AI is insufficient. The industry focus is shifting from building and training models to operating AI at scale and delivering real-world outcomes, emphasizing infrastructure over pure compute. Daily AI token consumption increased over 4x, from ~6 trillion to 26 trillion in 16 months, driven by a shift from human-to-AI to AI-to-AI interactions. This surge highlights bottlenecks in data delivery, particularly the KV cache, which provides working memory for GPUs. Optimizing data movement across the AI stack, including pooling GPU, CPU memory, and local storage for a larger virtual cache, is crucial. Legacy data architectures, designed for storage, are inadequate for AI's instant, high-throughput access needs. The solution involves adopting AI-native architectures built around inference and KV cache optimization to maximize ROI from existing GPUs.

Key takeaway

For AI Architects and MLOps Engineers scaling AI deployments, recognize that simply adding GPUs will not solve performance bottlenecks. Your focus must shift to optimizing the entire AI infrastructure, particularly data delivery and KV cache management. Prioritize designing AI-native architectures that ensure high throughput and low latency for inference, rather than adapting legacy systems. This approach will maximize ROI from existing compute resources and ensure scalable, secure, and compliant AI operations.

Key insights

AI success now hinges on optimizing the entire infrastructure stack, not just adding more GPUs.
