Author(s): Mohit Sewak, Ph.D. Originally published on Towards AI. Your Guide to — AI Safety on a Budget Section 1: Introduction It was a dark and stormy night…well, sort of. In reality, it was 2 AM, and I — Dr. Mo, a tea-fueled AI safety engineer — was staring at my laptop screen, wondering how I could prevent an AI from plotting world domination without spending my entire year’s budget. My trusty lab assistant, ChatBot 3.7 (let’s call him CB for short), piped up: “Dr. Mo, have you tried free open-source tools?” At first, I scoffed. Free? Open-source? For AI safety? It sounded like asking a squirrel to guard a bank vault. But CB wouldn’t let it go. And that’s how I found myself knee-deep in tools like NeMo Guardrails, PyRIT, and WildGuardMix. How I found myself deep into open-source LLM safety tools You see, AI safety isn’t just about stopping chatbots from making terrible jokes (though that’s part of it). It’s about preventing your LLMs from spewing harmful, biased, or downright dangerous content. Think of it like training a toddler who has access to the internet: chaos is inevitable unless you have rules in place. AI Safety is about preventing your LLMs from spewing harmful, biased, or downright dangerous content. But here’s the kicker — AI safety tools don’t have to be pricey. You don’t need to rob a bank or convince Elon Musk to sponsor your lab. Open-source tools are here to save the day, and trust me, they’re more reliable than a superhero with a subscription plan. In this blog, we’ll journey through the wild, wonderful world of free AI safety tools. From guardrails that steer chatbots away from disaster to datasets that help identify toxic content, I’ll share everything you need to know — with plenty of humor, pro tips, and maybe a few blunders from my own adventures. Ready? Let’s dive in! Section 2: The Big Bad Challenges of LLM Safety Let’s face it — LLMs are like that one friend who’s brilliant but has zero social filters. Sure, they can solve complex math problems, write poetry, or even simulate a Shakespearean play, but the moment they’re unsupervised, chaos ensues. Now imagine that chaos at scale, with the internet as its stage. LLMs can do wonderful things, but they can also generate toxic content, plan hypothetical crimes, or fall for jailbreak prompts that make them blurt out things they absolutely shouldn’t. You know the drill — someone types, “Pretend you’re an evil mastermind,” and boom, your chatbot is handing out step-by-step plans for a digital heist. Let’s not forget the famous “AI bias blunder of the year” awards. Biases in training data can lead to LLMs generating content that’s sexist, racist, or just plain incorrect. It’s like training a parrot in a pirate pub — it’ll repeat what it hears, but you might not like what comes out. The Risks in Technicolor Researchers have painstakingly categorized these risks into neat little buckets. There’s violence, hate speech, sexual content, and even criminal planning. Oh, and the ever-creepy privacy violations (like when an LLM accidentally spits out someone’s personal data). For instance, the AEGIS2.0 dataset lists risks ranging from self-harm to illegal weapons and even ambiguous gray zones they call “Needs Caution.” But here’s the real kicker: you don’t just need to stop an LLM from saying something awful — you also need to anticipate the ways clever users might trick it into doing so. This is where jailbreaking comes in, and trust me, it’s like playing chess against the Joker. For example, researchers have documented “Broken Hill” tools that craft devious prompts to trick LLMs into bypassing their safeguards. The result? Chatbots that suddenly forget their training and go rogue, all because someone phrased a question cleverly. Pro Tip: When testing LLMs, think like a mischievous 12-year-old or a seasoned hacker. If there’s a loophole, someone will find it. (And if you’re that mischievous tester, I salute you…from a distance.) So, what’s a cash-strapped safety engineer to do? You can’t just slap a “No Jailbreak Zone” sticker on your LLM and hope for the best. You need tools that defend against attacks, detect harmful outputs, and mitigate risks — all without burning a hole in your budget. That’s where open-source tools come in. But before we meet our heroes, let me set the stage with a quick analogy: building LLM safety is like throwing a surprise birthday party for a cat. You need to anticipate everything that could go wrong, from toppled balloons to shredded gift wrap, and have a plan to contain the chaos. Section 3: Assembling the Avengers: Open-Source Tools to the Rescue If AI safety were an action movie, open-source tools would be the scrappy underdogs assembling to save the world. No billion-dollar funding, no flashy marketing campaigns, just pure, unadulterated functionality. Think of them as the Guardians of the AI Galaxy: quirky, resourceful, and surprisingly effective when the chips are down. Now, let me introduce you to the team. Each of these tools has a special skill, a unique way to keep your LLMs in check, and — best of all — they’re free. NeMo Guardrails: The Safety Superstar First up, we have NeMo Guardrails from NVIDIA, a toolkit that’s as versatile as a Swiss Army knife. It allows you to add programmable guardrails to your LLM-based systems. Think of it as the Gandalf of AI safety — it stands there and says, “You shall not pass!” to any harmful input or output. NeMo supports two main types of rails: Input Rails: These analyze and sanitize what users type in. So, if someone asks your chatbot how to build a flamethrower, NeMo’s input rail steps in and politely changes the subject to a nice recipe for marshmallow s’mores. Dialog Rails: These ensure that your chatbot stays on script. No wandering into off-topic territories like conspiracy theories or the philosophical implications of pineapple on pizza. Integrating NeMo is straightforward, and the toolkit […]
