Introduction: LLM applications face unique security challenges—prompt injection, data leakage, jailbreaking, and harmful content generation. Traditional security measures don’t address these AI-specific threats. This guide covers defensive techniques for production LLM systems: input sanitization, prompt injection detection, output filtering, rate limiting, content moderation, and audit logging. These patterns help you build LLM applications that are […]

Prompt Injection Defense: A Complete Guide to Sanitization, Detection, and Output Validation
Prompt injection represents one of the most critical security vulnerabilities in LLM applications. As organizations deploy AI systems that process user inputs, understanding and defending against these attacks becomes essential for building secure, production-ready applications. Understanding Prompt Injection Attacks Prompt injection occurs when an attacker crafts malicious input that manipulates the LLM into ignoring its […]
Read more →Prompt Optimization: From Few-Shot to Automated Tuning
Introduction: Prompt engineering is both art and science—small changes in wording can dramatically affect LLM output quality. Systematic prompt optimization goes beyond trial and error to find prompts that consistently perform well. This guide covers proven optimization techniques: few-shot learning with carefully selected examples, chain-of-thought prompting for complex reasoning, structured output formatting, prompt compression for […]
Read more →Prompt Versioning and A/B Testing: Engineering Discipline for Prompt Management
Introduction: Prompts are code—they define your application’s behavior and should be managed with the same rigor as source code. Yet many teams treat prompts as ad-hoc strings scattered throughout their codebase, making it impossible to track changes, compare versions, or systematically improve performance. This guide covers practical prompt management: version control systems for prompts, A/B […]
Read more →Prompt Templates and Versioning: Building Maintainable LLM Applications
Introduction: Production LLM applications need structured prompt management—not ad-hoc string concatenation scattered across code. Prompt templates provide reusable, parameterized prompts with consistent formatting. Versioning enables A/B testing, rollbacks, and tracking which prompts produced which results. This guide covers practical prompt template patterns: template engines and variable substitution, prompt registries, version control strategies, A/B testing frameworks, […]
Read more →Prompt Optimization Strategies: From Structure to Automatic Refinement
Introduction: Prompt optimization is the systematic process of improving prompts to achieve better LLM outputs—higher accuracy, more consistent formatting, reduced latency, and lower costs. Unlike ad-hoc prompt engineering, optimization treats prompts as artifacts that can be measured, tested, and iteratively improved. This guide covers the techniques that make prompts more effective: structural patterns that improve […]
