Chain-of-experts (CoE): A lower-cost LLM framework that increases efficiency and accuracy

Introduction

In the constantly evolving landscape of artificial intelligence, large language models (LLMs) have become a cornerstone of various applications across industries. However, despite their impressive capabilities, organizations often face challenges such as high operational costs and varying levels of accuracy. To address these issues, researchers and professionals in the AI space have introduced the concept of a Chain of Experts (CoE), designed to optimize the use of LLMs while minimizing costs and improving overall efficiency.

What is a Chain of Experts?

A Chain of Experts (CoE) refers to a framework that incorporates specialized entities, or „experts,“ which are leveraged to enhance the performance of LLMs. Instead of relying solely on a single, general-purpose model, the CoE approach promotes a network of models that can focus on specific tasks or domains. This allows for higher accuracy and efficiency by ensuring that the most suitable model is utilized for each particular task.

Benefits of the CoE Framework

The CoE framework offers several advantages over traditional LLM implementations. First and foremost, it significantly reduces operational costs by enabling organizations to select and deploy only the necessary models for specific tasks. This targeted approach minimizes wastage associated with using a large, general model for every application.

Moreover, the use of specialized experts means that the models can achieve higher accuracy levels. Each expert is trained on a specific domain, allowing it to make more informed predictions and recommendations compared to a more generalized model. This tailored solution is particularly valuable in industries where precision is paramount, such as healthcare, finance, and legal services.

Implementing the CoE Strategy

Implementing a Chain of Experts strategy involves several crucial steps. Organizations must first identify the various tasks that can benefit from specialized models. Next, they need to select or develop these expert models to address each identified task. This phase may involve training these models on relevant datasets to ensure they possess the required knowledge and capabilities.

Once the expert models are in place, organizations can establish a system for routing tasks to the appropriate expert based on task specifications. This may involve a machine learning pipeline where an initial model assesses the task and directs it to the correct expert.

Case Study: Real-World Applications

Several organizations have begun to adopt the Chain of Experts framework, with promising results. For instance, in the healthcare sector, one research lab utilized a CoE to enhance diagnostic accuracy. By employing expert models tailored for different medical specialties, they achieved a significant increase in the rate of accurate diagnoses, ultimately improving patient outcomes.

Similarly, businesses in finance have leveraged the CoE framework to refine their algorithmic trading strategies. By employing experts trained on specific market conditions, they reduced the risk of erroneous trades and improved overall profitability.
