Vercel Functions can now run on Fluid compute, bringing improvements in efficiency, scalability, and cost effectiveness. Fluid is now available for all plans.

Link to headingWhat’s New

• Optimized concurrency: Functions can handle multiple requests per instance, reducing idle time and lowering compute costs by up to 85% for high-concurrency workloads

• Cold start protection: Fewer cold starts with smarter scaling and pre-warmed instances

• Optimized scaling: Functions scale before instances, moving beyond the traditional 1:1 invocation-to-instance model

• Extended function lifecycle: Use waitUntil to run background tasks after responding to the client

• Runaway cost protection: Detects and stops infinite loops and excessive invocations

• Multi-region execution: Requests are routed to the nearest of your selected compute region for better performance

• Node.js and Python support: No restrictions on native modules or standard libraries
