How Fluid compute works on Vercel
Vercel's Fluid compute cuts serverless waste in half. Here's how it reuses resources instead of spinning up new ones.

Why it matters
Vercel is shipping infrastructure that solves a real pain point for AI workloads: serverless architectures waste compute while waiting on model inference. Fluid compute's dynamic routing and resource reuse directly addresses latency and cost for AI-heavy applications.

Publisher excerpt: designed to handle modern workloads with real-time scaling, cost efficiency, and minimal overhead. Traditional serverless architectures optimize for fast execution, but struggle with requests that spend significant time waiting on external models or APIs, leading to wasted compute. Fluid compute is…
