New benchmark reveals LLMs struggle with in-context watermarking instructions

Researchers have developed a new benchmark, ICWBench, to evaluate how well large language models follow in-context watermarking instructions. Their evaluation of 14 LLMs revealed that none could consistently achieve both high detectability and answer quality. To address this, they proposed a two-stage training method, self-distillation with logits perturbation (SDLP) and reinforcement learning, which significantly improved performance on Qwen3-14B and GPT-OSS-20B while maintaining response quality.

    Learning to Follow In-Context Watermark Instructions via Self-Distillation

    arXiv:2608.29030v1 Announce Type: new Abstract: In-context watermarking (ICW) prepends an instruction to a query asking the model to embed a statistically detectable signal in its response. It thus equips LLMs with a watermarking interface that third parties can invoke without ac…
