Junior devs think it is a simple fetch call. They write a basic request. Users wait 15 seconds for a reply. The screen stays blank. It feels slow.
Mid-level devs use streaming. Tokens appear one by one. The app feels alive. Refresh the page and the chat vanishes. It has no memory.
Senior devs focus on persistence. They save the stream to a database in real time. Users return tomorrow and find their history. They handle auth and disconnects.
The breakdown:
- Junior: Simple request. Lacks speed.
- Mid: Streaming. Lacks memory.
- Senior: Streaming and saved history.
The gap is not the AI API. The gap is the infrastructure.
Ask if your chat app survives a page refresh. The silence tells the story.
