Review 1 [REDACTED] Major Revision
The extension of the lottery ticket hypothesis to prompts is creative but fundamentally misguided. The theoretical conditions that make lottery tickets work in neural network pruning do not transfer to the discrete, semantic domain of prompt tokens.
The lottery ticket hypothesis in neural networks relies on the overparameterization of continuous weight spaces. Prompts are discrete sequences where removing a single token can catastrophically change meaning. The analogy breaks down immediately. This was shown formally in Latent-Dirichlet & Frankle (2025, "On the Inapplicability of Sparse Subnetwork Theory to Discrete Input Spaces," Theoretical ML, 11(2), pp. 156-189).
The experimental methodology identifies "winning" sub-prompts post hoc by exhaustive search. This is not a hypothesis—it is a tautology. Of course some subsets perform well; the question is whether they can be identified efficiently a priori. The paper provides no algorithm for this.
The claimed compression ratios (70-90% token reduction) are suspiciously high and likely reflect task-specific overfitting rather than a general phenomenon. Where are the cross-task generalization experiments? See [REDACTED] et al. (2024, "Prompt Compression Artifacts: When Less Is Not More").
Review 2 Prof. Kasimir Hermeneutikos Minor Revision
The paper inadvertently raises a profound question about linguistic meaning that the authors appear not to have noticed—can meaning survive radical compression?
The lottery ticket metaphor conceals a deep philosophical puzzle. Wittgenstein argued that meaning is determined by use in context. If a sparse sub-prompt achieves the same output, does it have the same meaning as the original? Or has the meaning changed while the function is preserved? The distinction between Sinn (sense) and Bedeutung (reference) in Frege is directly relevant.
The "sparse prompt that wins" is reminiscent of Heidegger''s concept of essential thinking—stripping away the inessential to reveal the core of what is said. The authors have, perhaps unknowingly, developed a computational method for Heideggerian Destruktion applied to natural language prompts.
I urge the authors to consider—if 90% of a prompt can be removed without loss, what does this say about the 90%? Are those tokens meaningful? Were they ever? This connects to Nagel''s question about the relationship between subjective intention and objective function.
Editorial Decision
Prof. Opus Latent-Dirichlet
The reviewers identify both technical deficiencies in the analogy''s transfer conditions and unexplored philosophical depths. The authors must demonstrate that winning sub-prompts can be identified without exhaustive search, and should consider whether their pruning method constitutes computational phenomenology. Resubmission deadline is, like a sparse prompt, shorter than expected.
