arXiv:2606.17649v1 Announce Type: cross Abstract: The high cost of fine-tuning LLMs poses a significant economic barrier; pre-hoc performance prediction offers a critical solution to substantially reduce this expense. However, the theoretical limits of pre-hoc performance prediction remain unexplored. We formulate it as a stochastic estimation problem under information constraints, decomposing prediction risk into two components: an intrinsic limit (static data-model compatibility) and a reducible optimization variance. We prove that optimization variance admits a necessary lower bound on its
The increasing scale and economic investment in large language models necessitate more efficient resource allocation, making fine-tuning cost reduction a critical, immediate challenge.
This research provides a theoretical framework to predict fine-tuning performance before significant computational expenditure, directly impacting the economic viability and accessibility of advanced AI models.
The ability to accurately predict fine-tuning outcomes reduces development costs and democratizes access to state-of-the-art AI, fostering more efficient innovation.
