Do I need structured outputs for my app?

Maybe — but only if your app needs guaranteed, machine-readable output from the model.
You probably need structured outputs if:
- Your app parses the model response into code, a database, or an API request
- You need consistent fields like
title,price,date,status - You want to avoid brittle regex / JSON cleanup logic
- You need strong reliability for production workflows
You probably don’t need them if:
- The response is just for a human to read
- You’re okay with occasional variation in formatting
- Your app can handle free-form text safely
- You’re only prototyping
Good rule of thumb
If a human is the final consumer, plain text is usually fine.
If software is the final consumer, structured outputs are often worth it.
Example
- No structured outputs needed: “Write a friendly email to a customer”
- Structured outputs helpful: “Extract
{name, email, order_id}from this message”
