AI chatbot: cant get consistent JSON out of the model
Stuck point
my app needs structured JSON back from the model, but it randomly wraps it in markdown or adds a preamble, so my parser breaks maybe 1 in 5 times and the UI crashes.
progress status — how done is it, really?
that 23-pt gap is probably exactly where the last step is hiding.
What I need help with
how to force clean, parseable structured output every time.
Your first move
Give the model one example of the exact JSON you want and lower the temperature, then validate the response and retry once on a parse failure.
the road everyone walks
every shipped app walked this exact road. being stuck partway isn't failing, it's the middle of the climb — and the AI read (63%) puts this project roughly here.
next stop: real people use it · they find it and come back.

What's already working
the chat flow, streaming, and UI are all working when the JSON is clean.
The goal
a chatbot that reliably returns data my app can render.
