UAI 2026 researchers hit 2,500-character rebuttal wall

The UAI rebuttal limit is a structural bottleneck that disproportionately impacts papers with multiple reviewers or complex methodological critiques.

• –The 2,500-character cap is roughly half the standard ICML limit, forcing authors to prioritize brevity over comprehensive technical defense.
• –Using the "Official Comment" feature to extend a rebuttal is widely considered rule-bending and can be ignored or penalized by Area Chairs.
• –This restriction highlights the growing strain on conference logistics as submission volumes outpace the capacity of the peer review system.
• –Authors are pivoting to "micro-rebuttal" strategies, employing dense shorthand and prioritized point-by-point responses to survive the limit.
