Poor AI Connection = Extreme Lag

Describe the Bug

Sometimes when I run an agent request via Claude-4-sonnet-thinking, it has a MAJOR lag. Like it responds with one or two words every few seconds.

It used to happen maybe 2-3 times a day. But now it’s like every 2-3 agent messages I send are responding with this major lag. The only way to fix it is to click stop and resend the same message, and it’s like it gets a better connection or something. But obviously, it’s wasting my usage credits.

Steps to Reproduce

Simply send an agent message using claude-4-sonnet-thinking.

Expected Behavior

It should respond with a normal connection speed level instead of extreme lag.
