Surrogate Benchmarks for Model Merging Optimization
This paper introduces a groundbreaking method to drastically reduce the cost and time of creating high-performance, custom AI models. By replacing slow, expensive real-world tests with fast, accurate predictive models, this approach accelerates the development of advanced model merging techniques.
Executive Impact Summary
This research provides a direct path to slashing AI R&D costs. The "surrogate benchmark" methodology replaces GPU-intensive model merging evaluations (over 58 hours per run) with near-instantaneous, highly accurate predictions. This allows enterprises to innovate and deploy superior custom-merged LLMs faster and at a fraction of the cost, creating a significant competitive advantage.

Creating a single powerful AI model by merging multiple specialized models is a promising technique. However, finding the optimal 'recipe' or hyperparameters for this merge is a major challenge. The optimization process is incredibly computationally expensive, particularly for large language models (LLMs). Each hyperparameter configuration must be evaluated by performing the actual merge and testing the resulting model, a process that can take days and consume vast amounts of expensive GPU resources. This cost barrier severely limits the pace of innovation in developing better merging algorithms.
The solution proposed is a surrogate benchmark (SMM-Bench). Instead of performing the costly real-world evaluation, this approach uses a lightweight, pre-trained regression model (LightGBM) to predict the performance of a merged model based on its hyperparameters. To build this, the researchers first collected a large dataset of hyperparameter settings and their true performance scores. This data was then used to train the surrogate model, which can provide a performance estimate in milliseconds. This enables rapid, low-cost exploration of the entire hyperparameter search space.
The paper introduces two distinct benchmarks to cover different model merging scenarios. SMM-Bench-PS (Parameter Space) focuses on optimizing continuous hyperparameters for methods like Task Arithmetic, where model weights are directly aggregated. SMM-Bench-DFS (Data Flow Space) addresses a more complex, mixed-variable problem where layers from different source models are selectively stacked and scaled. By providing robust benchmarks for both continuous and mixed-variable optimization, the research offers a comprehensive toolkit for the AutoML community.
For enterprises, this methodology is a game-changer for custom AI development. It dramatically lowers the barrier to entry for creating bespoke, high-performance models. Key impacts include: massive cost savings on GPU infrastructure, accelerated R&D cycles for developing proprietary merging techniques, and the ability to conduct comprehensive, reproducible comparisons of different optimization algorithms. This democratizes advanced model optimization, allowing teams to achieve state-of-the-art results without state-of-the-art budgets.

Case Study: Validating the SMM-Bench
The researchers demonstrated the benchmark's value by comparing standard optimization algorithms (like CMA-ES and TPE) on both the 'true,' expensive process and their new surrogate benchmark.
Finding: The results showed that the optimization behaviors and performance trajectories on the fast surrogate benchmark closely mirrored the slow, real-world process. This proves the benchmark's ability to reliably simulate and predict optimization outcomes, making it a valid tool for low-cost algorithm development and validation.
