This isn't really convincing, since you can do this even without showing the prediction at all. Simply ask the model to predict what the user will send, then show the actual next prompt, and done. The only reason to show this would be to influence the user's next prompt, which the article doesn't touch on.
I think your theory is probably right but I have never once used the suggested message
We had processor level branch predictors. Now do we not only pre fill the next prompt, why not just start generating the response as well?
Interesting thought at least.

I think this analysis is spot on.
I haven't noticed this yet. Was this added recently?
no, this has been around for months. it shows up as greyed out text that needs a tab/arrow interaction to materialize. 2.0.69 apparently (since .70 fixed a bunch of bugs in it). https://github.com/anthropics/claude-code/blob/main/CHANGELO...
