Researchers have explored a new method for compressing large language models (LLMs) called ROCKET-ActCost, which aligns the allocation cost with an output-space objective. When applied to Qwen3-8B at 50% compression, ROCKET-ActCost showed a slight improvement in average accuracy across zero-shot benchmarks but resulted in a higher WikiText perplexity. The study found that different allocation objectives can lead to trade-offs between accuracy and perplexity, and the correlation between weight-space and output-space errors limits the divergence of these methods.
