TL;DR: Build a production-ready AI API that runs globally in under 20 minutes—no servers, no scaling headaches, sub-300ms responses worldwide.
Ever wonder why your AI app feels sluggish even with fast models? I was getting 2-3 second response times from OpenAI calls that made my users abandon conversations mid-stream. That's when I discovered Cloudflare Workers AI could handle the same workload with sub-300ms response times globally—while keeping costs competitive with major providers.
What You'll Build
A simple but powerful LLM API that:
Takes user prompts, system prompts, and temperature settings
Runs on Cloudflare's edge network (300+ locations)
Responds in under 300ms globally
Costs competitively with commercial APIs
Scales automatically without infrastructure management
This isn't theoretical—I migrated 78% of Sparkry.AI's inference to this setup and improved response times by 85% while maintaining comparable costs to our previous OpenAI setup.
