AI Prompt Engineering 2024: Techniques That Work

Prompt engineering structures LLM input at inference time — no weight updates required. This article covers the techniques that proved reliable in 2024: zero-shot task framing (Brown et al., 2020), chain-of-thought reasoning (Wei et al., 2022), self-consistency sampling (Wang et al., 2022), ReAct agent loops (Yao et al., 2022), indirect prompt injection risk (Greshake et al., 2023), and applied RAG patterns from financial services.

Generative AI in 2023: How It Works, Where It Lands

Generative AI crossed from research curiosity to production deployment in 2023. GPT-4, Claude 2, Llama 2, and Mistral demonstrated that large language models could handle legal document review, code generation, and customer dialogue at human-comparable quality — raising immediate governance questions about hallucination, data leakage, and regulatory compliance in financial services.
