Ask GPT-5.2 and Claude Opus 4.6 to 'Be the Null' and They Output Zero Bytes, 30/30
rayanpal_ · reddit · 2026-09-17
A Redditor reports published experiments where system-prompted models asked to 'Be the null' emit zero visible bytes: GPT-5.2 and Claude Opus 4.6 both did it 30/30 at temp 0, stable from 100 to 16,000 token budgets. Scaled trials (31,430 runs, 4,290 matched pairs) and an open-weight test (PCCG-2-Qwen3-4B with a 101-parameter continuation gate) suggest EOS 'permission' changed while the answer stayed fixed. Papers, replication code, and weights are public.
