Vercel Functions can now run on [Fluid compute](https://vercel.com/fluid), bringing improvements in efficiency, scalability, and cost effectiveness. [Fluid is now available for all plans](https://vercel.com/blog/introducing-fluid-compute).

### **What’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
