vLLM adds AI text watermarking using the Gumbel-max trick

Original: vLLM ajoute le watermarking de texte via le Gumbel-max trick : bruit pseudo-aléatoire dérivé d'une clé secrète et des 4

vLLM has added text watermarking based on the Gumbel-max trick: pseudo-random noise derived from a secret key and the last four tokens is applied without altering the generated text. The developer reports quality gaps of under 2 points on GSM8K, MBPP and IFEval benchmarks, with a signal that can be detected without access to the underlying model. The feature is drawing attention among people following AI-generated content detection.

Why now: Interest in detecting AI-generated text keeps growing, and this is a practical watermarking implementation in a widely used inference engine.
