Here's a trick for finding bugs and DX gaps in your REST APIs: have an AI one shot a consumer app using the APIs.
Do not tell the AI that the goal is to find bugs or it'll start optimizing for that. Just ask it to build the app.
When done, ask for every issue it hit and explicitly ask for all the workarounds that it built bcs it has silently patched things behind the scenes, added hack code just to get the job done. That's your bug list.
I did this last night with GPT-6 Astra on a few one shot demo apps and it found some hidden issues that tripped it up. I got the list, switched to Opus 5, asked it to verify every single issue independently and then file ticket with details. Result: fewer bugs, better DX.
OpenAI’s new GPT Realtime model is now live on Vapi!
We got early access from OpenAI and were impressed: latency improvements are significant, voices are more natural, multilingual switching is great, accent imitation is impressive, and instruction following is more reliable.
