Open Source Large Language Models: An Overview

In the rapidly evolving landscape of artificial intelligence, particularly with the rise of generative AI, organizations are increasingly turning to AI guardrails to ensure their AI systems operate safely, ethically, and in alignment with company values. Much like guardrails on highways protect vehicles from veering off course, AI guardrails are designed to prevent AI systems from producing harmful, inaccurate, or inappropriate content. These guardrails serve multiple crucial functions. They help maintain privacy and security by protecting against malicious attacks that could manipulate AI-generated outcomes. They also ensure regulatory compliance, which is particularly important as government scrutiny of AI intensifies. Perhaps most importantly, AI guardrails help build and maintain trust with customers and the public by continuously monitoring and reviewing AI-generated outputs. There are several types of AI guardrails, each addressing specific risks:1. Appropriateness guardrails filter out toxic, harmful, or biased content.2. Hallucination guardrails prevent the generation of factually incorrect or misleading information.3. Regulatory-compliance guardrails ensure adherence to relevant laws and standards.4. Alignment guardrails keep generated content in line with user expectations and brand consistency.5. Validation guardrails check that content meets specific criteria. AI guardrails typically consist of four main components: a checker that scans for issues, a corrector that refines and improves outputs, a rail that manages the interaction between the checker and corrector, and a guard that oversees the entire process. Implementing AI guardrails at scale requires a multidisciplinary approach. Organizations should design guardrails with input from diverse stakeholders, define clear content quality metrics, and adopt a modular approach for easy integration and scalability. It's also crucial to develop new capabilities and roles within the organization to manage these systems effectively. While AI guardrails don't guarantee completely risk-free AI systems, they are a critical tool in creating a safer environment for AI innovation and transformation. As AI continues to advance, we can expect to see not only new types of AI systems but also evolving standards for their development and operation, with guardrails playing a central role in responsible AI implementation.
