Towards Harnessing the Collaborative Power of Large and Small Models for Domain Tasks

arXiv:2504.17421v2 Announce Type: replace Abstract: Large language models (LMs) offer broad generalization capabilities but require vast amounts of data and computational resources for domain-specific tasks; small models (SMs), in contrast, are more efficient and tailored to specific domains yet lack general-purpose coverage. Taking a collaborative approach, where large and small models work synergistically, can accelerate the adaptation of LLMs to private domains and unlock new potential in AI. This survey presents a comprehensive overview of recent advances and challenges in harnessing the c

Why this matters
Why now

The accelerating development and deployment of large language models are highlighting their computational and data demands, making collaborative approaches with smaller, specialized models a practical necessity for broader domain adoption.

Why it’s important

This survey indicates a maturation in AI development strategies, moving beyond a 'bigger is always better' paradigm to more efficient and adaptable hybrid models, crucial for enterprise and closed-domain AI applications.

What changes

The focus shifts from purely monolithic large models to architectures that strategically integrate the strengths of both large and small models, enabling more efficient and tailored AI solutions for specific domains.

Winners
  • · Enterprises with private data
  • · Small to medium AI developers
