Sometimes when writing a prompt the CLI omits typed characters and also the backspace does not work properly, sometimes deleting and sometimes re-adding content
This was via SSH on remote Linux box, local MacBook. Not tested locally
Not sure if the animations have anything to do, or the model generating content at the same time we type in the box
Steps to Reproduce
It is sporadic, not sure
Expected Behavior
Typed chars should appear
Backspace should only delete previous chars

MacOS

Hey, thanks for the detailed report. This is a known issue. When the CLI is busy like during active generation or render streaming, keys typed at that moment can get dropped, or backspace can behave incorrectly. It’s more noticeable over SSH because the network can merge several keypresses into one packet, and they arrive to the CLI in a batch.
We fixed part of these cases in early July, but your scenario, especially mid-chunk backspace and typing over SSH, is still in the remaining set. We’re tracking the issue, but I can’t share an exact ETA for the fix yet.
For now, the workaround is:
type a bit more slowly while generation is active
if possible, run the CLI locally instead of over high-latency SSH since it happens much less often
Your guess about the model generating content while you type is basically right. Streaming loads the event loop, and that’s what triggers the input batching. I’ll post an update in the thread once we have one.
