⚡ They rewrote JSONata with AI and cut infrastructure costs hard#
Reco used the same approach Cloudflare used in other rewrites: start from the test suite, let AI implement, and keep going until everything passes. The result was gnata, a Go implementation of JSONata 2.x.
What stands out#
- 🚀 1,000x faster on simple expressions
- 💸 $400 in tokens for a high-impact change
- 🧪 1,778 official tests passing
- 🧠 Removed an expensive, slow RPC layer
The point is not “use AI and you’re done”, but to use it with tests, verification, and tightly scoped refactors.
🪄 Quick explanation#
Think of replacing a slow tool with a custom-built version.
AI helps you build fast, but the real value appears when the code passes tests and cuts real costs.
👉 AI + tests + a good strategy = real impact.
