AI & LLM Primer

Show Notes

In this episode, we face the economic and physical realities of deploying AI. A model’s theoretical capability matters little if it is too slow, too expensive, or too power-hungry to run. We explore the "tradeoff triangle" engineers must navigate to turn a research artifact into a sustainable product. Join us as we: • Weigh the Returns: We analyze Model Size vs. Capability, discussing empirical scaling laws and the point of "diminishing returns" where making a model bigger no longer pays off. • Measure the Speed: We distinguish between Latency (how fast a single user gets an answer) and Throughput (how many users the system can handle), explaining why optimizing for one often hurts the other. • Calculate the Bill: We look at the hard costs of Inference, breaking down how context length and token count directly impact memory usage, energy consumption, and cloud bills. • Compress the Math: We explain Quantization, a technique that reduces the numerical precision of a model (e.g., from 32-bit to 8-bit) to drastically cut memory usage without destroying intelligence. • Move to the Edge: We discuss On-Device Deployment, examining the challenges and privacy benefits of running powerful AI locally on phones and laptops instead of the cloud. This episode is a reality check for anyone wondering why the smartest model isn't always the right choice for the job.

This chapter examines prompt injection and jailbreak attacks, which exploit a language model's inherent inability to distinguish between authoritative developer instructions and untrusted user data. It covers the mechanics of direct and indirect injection, categorises common jailbreaking techniques, discusses the limitations of defensive prompt engineering, and outlines a layered mitigation strategy to better defend production systems.

This chapter examines data security and privacy throughout the LLM lifecycle. It explores the inherent risks of training data, such as copyright issues, personal information (PII) contamination, and data poisoning. Additionally, it details how models can leak sensitive information through memorization and extraction attacks, and outlines operational defenses for securing systems, including input redaction pipelines, encryption, tenant isolation, and data retention policies.

This chapter adapts traditional threat modeling frameworks (such as STRIDE, PASTA, and attack trees) specifically for the unique vulnerabilities of LLM systems. It guides defenders through identifying AI-specific assets and adversaries, and provides a step-by-step procedure for building a living threat model that can be maintained alongside the system's codeAmazon.com: LLM Primer VII AI Security: Defending LLM Systems Against Prompt Injection, Jailbreaks, and Adversarial Threats: 9798185644065: SHIMODA, SHO: Books

This chapter explains that AI security fundamentally and structurally differs from traditional software security. Instead of finding and patching clear bugs in readable source code, defenders must secure probabilistic models whose behaviors are driven by billions of uninterpretable weights and training data. Consequently, the security focus shifts from ensuring code correctness to managing and restricting an unbounded range of unpredictable inputs and outputs.

This episode covers Chapter 7, examining why Large Language Models confidently generate false information. We discuss the probabilistic nature of "hallucinations," the dangerous gap between fluency and correctness, and practical strategies like calibration and hybrid verification to align model confidence with reality.
