Chat vs Direct Calls

Memory is not automatic.

In chat tools, it feels like the AI remembers everything. But that’s because the system sends previous messages for you. Here, nothing is remembered automatically. Each run is independent. If you want the model to remember something, you must include it in the prompt. This is a key shift: Memory is not built-in — it is something you provide.

Same question, different result

No context

What’s my favorite color?

With context

User said: My favorite color is blue. Question: What’s my favorite color?

Without context, the model guesses. With context included, it answers correctly.

Takeaway

If you don’t include the context, the model doesn’t know it.

Challenge

Make It Remember

Run a prompt where the model forgets, then fix it by adding context.
