Why ChatGPT sucks at generating Types (and how I fixed it)

Have you ever pasted a JSON payload into ChatGPT and asked it to generate a TypeScript interface or Go struct?

Usually, it works. But sometimes, it decides to be "helpful" and changes your user_id to UserId, or completely forgets an optional field. In a production CI/CD pipeline, this kind of AI hallucination is a nightmare.

I got tired of this, so I built TypeFlow: A developer tool that converts JSON, SQL, or YAML into 16+ languages instantly. But the real secret isn't just AI—it's a Hybrid Architecture.

The Problem: AI is smart, but unpredictable

When dealing with Data Transfer Objects (DTOs), schemas, and type definitions, you need 100% deterministic output. If an AI "guesses" a type wrong, your app crashes.
