What is Retrieval-Augmented Generation?

First Reported on: fortune.com

The artificial intelligence realm is currently abuzz with a novel method called retrieval-augmented generation (RAG), which allows AI models to temporarily access external data without experiencing any alterations. Unlike fine-tuning, in which a fresh dataset is employed to adapt an existing model, RAG aims to introduce the AI system to new information and encourages it to integrate this data into its responses. With RAG, AI models have the capability to provide more accurate and contextually relevant responses by utilizing the external data source as a reference. This transformative approach not only improves the quality of the AI-generated content but also significantly enhances its adaptability and versatility in addressing a wide range of complex tasks.

RAG explained

According to Sriram Raghavan, IBM Research AI’s vice president, RAG is a straightforward process. A user collects specific documents or texts and provides them to the model, accompanied by a request such as ‘Answer this question’ or ‘Summarize this’. The model executes the task and proceeds to another RAG function without retaining any prior data. The simplicity and reduced intricacy of RAG have rendered it a preferred alternative to fine-tuning and prompt engineering. RAG’s primary advantage lies in its ability to save computational resources and provide relevant responses without the need for excessive data mining. Its focus on only pertinent information ensures precise output, making it an efficient choice for both experts and amateurs in various fields.

Employment of RAG with LLMs

Employing RAG with large language models (LLMs) has only become feasible due to the staggering capabilities of modern AI models. Raghavan believes that this approach has become popular in the last six to nine months. RAG is an incredibly practical method for those seeking to create applications using existing LLMs, only requiring a single document or a few examples. As a result, developers can leverage the power of LLMs without having to invest in building complex models from scratch. Moreover, the RAG approach streamlines the process of extracting valuable information, making it easier for users to implement AI-powered solutions in various industries and applications.

Challenges with RAG

However, RAG does have its difficulties. As AI models progress, retrieval turns into a more complicated task. Users must supply precise input, possibly necessitating an exploration of a vast range of documents to ascertain their pertinence, dividing them, or converting complex PDF documents filled with tables, charts, and diagrams. Moreover, this complexity adds a considerable amount of time and effort to the information retrieval process, potentially reducing the efficiency of AI models. Therefore, it is crucial to develop advanced techniques and algorithms to help mitigate these challenges and streamline information extraction from diverse sources.

Support from major tech companies

Major technology companies are now concentrating on aiding developers in implementing RAG. IBM is designing patterns and “cookbooks” offering guidance for applying RAG in various application development contexts. Microsoft, Google, and Amazon are also working on their own RAG solutions, making it simpler for businesses to harness the power of LLMs. These tech giants are providing comprehensive documentation, tools, and resources to facilitate a seamless integration of RAG into existing systems. As a result, developers can more readily adopt LLM capabilities which in turn improves the overall efficiency, responsiveness, and effectiveness of AI applications across different industries.

Global AI governance initiatives

In the meantime, the United Nations Secretary-General has established a High-Level Advisory Body on AI to review current AI governance efforts and deliver initial recommendations by year’s end. This esteemed group of experts and visionaries will work together to address the ethical, social, and economic implications of AI technologies on a global level. Their insights will provide invaluable guidance for policymakers and stakeholders, paving the way for responsible and sustainable AI development that benefits all of humanity.

US President’s executive order on AI

Furthermore, US President Joe Biden is expected to issue an executive order on AI, requiring evaluations of sophisticated AI models prior to their deployment by federal employees. This executive order aims to ensure that artificial intelligence systems used by the government are held to high standards of safety, fairness, and efficiency. By conducting thorough assessments of AI models, federal agencies can minimize potential risks and unintended consequences, while maximizing the benefits that these advanced technologies can provide in advancing national interests and solving complex challenges.
