Researchers find 'meta-tokens' that expose hidden model computation in Qwen3.6-27B

Researchers used J-lens on Qwen3.6-27B to identify 'meta-tokens'—tokens that reveal non-obvious computation inside the model. They found that 什么意思 ("what does this mean") fires when the model encounters ambiguous text, 大概率 ("most likely") activates before the model hedges, and "gcd" appears during logical computation problems, each triggering specific algorithmic behavior.
