What if your LLM firewall could learn which safety system to trust—on the fly?

In this episode, we dive deep into the evolving landscape of content moderation for large language models (LLMs), exploring five competing paradigms built for scale. From the principle-driven structure of Constitutional AI to OpenAI’s real-time Moderation API, and from open-source tools like LLaMA Guard to Salesforce’s BingoGuard, we unpack the strengths, trade-offs, and deployment realities of today’s AI safety stack. At the center of it all is AEGIS, a new architecture that blends modular fine-tuning with real-time routing using regret minimization—an approach that may redefine how we handle moderation in dynamic environments.

Whether you're building AI-native products, managing risk in enterprise applications, or simply curious about how moderation frameworks work under the hood, this episode provides a practical and technical walkthrough of where we’ve been—and where we're headed.

• 🧠 What makes Constitutional AI a scalable alternative to RLHF—and how it bootstraps safety through model self-critique.
• ⚙️ Why OpenAI’s Moderation API offers real-time inference-level control using custom rubrics, and how it trades off nuance for flexibility.
• 🧩 How LLaMA Guard laid the groundwork for open-source LLM safeguards using binary classification.
• 🧪 What “Watch Your Language” reveals about human+AI hybrid moderation systems in real-world settings like Reddit.
• 🛡️ Why BingoGuard introduces a severity taxonomy across 11 high-risk topics and 7 content dimensions using synthetic data.
• 🚀 How AEGIS uses regret minimization and LoRA-finetuned expert ensembles to route moderation tasks dynamically—with no retraining required.

If you care about AI alignment, content safety, or building LLMs that operate reliably at scale, this episode is packed with frameworks, takeaways, and architectural insights.
