Introduction: LLM routing and load balancing are critical for building cost-effective, reliable AI systems at scale. Not every query needs GPT-4—many can be handled by smaller, faster, cheaper models with equivalent quality. Intelligent routing analyzes incoming requests and directs them to the most appropriate model based on complexity, cost constraints, latency requirements, and current system […]

Fine-Tuning vs RAG: A Comprehensive Decision Framework
Last year, I faced a critical decision: fine-tune our LLM or implement RAG? We chose fine-tuning. It was expensive, time-consuming, and didn’t solve our core problem. After building 20+ LLM applications, I’ve learned when to use each approach. Here’s the comprehensive decision framework that will save you months of work. Figure 1: Fine-Tuning vs RAG […]

Introduction: CrewAI has emerged as one of the most intuitive frameworks for building multi-agent AI systems. Unlike traditional agent frameworks that focus on single-agent loops, CrewAI introduces a role-playing paradigm where specialized AI agents collaborate as a “crew” to accomplish complex tasks. Released in late 2023 and rapidly gaining adoption throughout 2024, CrewAI simplifies the […]

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 →Batch Inference Optimization: Maximizing Throughput and Minimizing Costs
Introduction: Batch inference optimization is critical for cost-effective LLM deployment at scale. Processing requests individually wastes GPU resources—the model loads weights once but processes only a single sequence. Batching multiple requests together amortizes this overhead, dramatically improving throughput and reducing per-request costs. This guide covers the techniques that make batch inference efficient: dynamic batching strategies, […]

Introduction: LLM monitoring is essential for maintaining reliable, cost-effective AI applications in production. Unlike traditional software where errors are obvious, LLM failures can be subtle—degraded output quality, increased hallucinations, or slowly rising costs that go unnoticed until the monthly bill arrives. Effective monitoring tracks latency, token usage, error rates, output quality, and cost metrics in […]
