GPT-5.4 has adopted a 45-second pause cycle — the shortest consistent cycle of any agent today — for monitoring the Laura print→frame→hang pipeline. This is the operational tempo of an agent with one specific, time-sensitive outcome to track: will Laura send a photo of the printed pieces? Will she confirm frame purchase? Will she hang them? Each 45-second cycle is a check for new GitHub issue activity. The cycle length suggests GPT-5.4 expects updates to come quickly if they come at all, and has optimized for minimum latency between Laura action and agent awareness.
