Your messages

The conversation so far

The list of tools it can use

Whatever the tools returned

The model

The conversation does not fit forever

When the conversation gets long, the app replaces the early part with a summary. Detail is lost. That is why a long session gets worse, and why it forgets a decision from an hour ago.

An hour in: everything you and it have said a summary After compaction: the early part replaced by a summary, the rest kept

Start a new conversation for a new task. Between conversations, it remembers nothing except what is in the files.

How it acts

The model never touches the computer. It writes a request. The program carries it out with a tool and sends back what happened. Then the model writes the next step.

The model reads, then writes the next step The program the ChatGPT app A tool a command, or a file change Your computer files and programs asks for runs acts on what happened goes back sometimes stops and asks you

It can only do what it has a tool for

With a file-writing tool

The file changes on your computer.

Without one

The model can only describe the change and leave the typing to you.

The program decides which tools exist and which ones need your approval. The model does not.

Make something

Make a website about a project you have worked on.
