AI writes answers token by token. That is why it streams onto the screen.
7 min · Reviewed 2026
The big idea
AI writes its answer one token at a time. The screen 'streams' the words as soon as each token is ready.
Some examples
It is not pretending to type — it really makes one chunk at a time.
Streaming lets you read while AI is still thinking.
If the answer freezes, AI may be stuck on the next token.
You can stop AI mid-stream if you see it going wrong.
Try it!
Watch AI write a long answer. You can press stop the moment you see it going off-track.
