AI prompt engineering fundamentals and red teaming

Prompt engineering is not dying; it evolves with each model release.

People repeatedly claim prompt engineering will become unnecessary with the next model, yet each new release still benefits from refined prompting techniques.

Why: LLMs require human-like social intelligence to elicit optimal performance, a concept termed 'artificial social intelligence'.

"people will kind of always be saying it's dead or it's going to be dead with the next model version, but then it comes out and it's not"

Providing examples dramatically improves model performance.

Instead of describing a desired style or output, show the model 2-5 concrete examples of inputs and expected outputs.

Why: Examples activate patterns learned during training more effectively than abstract descriptions.

"just by giving it examples of what you want, you can really, really boost its performance"

Break complex tasks into subproblems before solving.

Ask the model to first list all subproblems that need solving, then address each systematically before combining results.

Why: Reduces cognitive load and allows distributed processing across tools or agents.

"what are some subproblems that would need to be solved first?"

Models can improve their own outputs through iterative refinement.

Generate an initial response, then prompt the model to critique and improve its own answer in 1-3 iterations.

Why: Leverages the model's ability to evaluate and correct its own reasoning.

"can you go and check your response... then to improve itself"

Rich context prevents performance cliffs.

Include comprehensive background information, but place it at the prompt's beginning for caching benefits and to prevent task drift.

Why: Models perform better with domain-specific context, and leading placement optimizes token usage.

"including context or additional information about the situation was super, super important"

Roles only help for expressive, not accuracy-based tasks.

Telling an LLM 'you are a math professor' no longer improves factual accuracy but can enhance stylistic outputs like writing or summaries.

Why: Modern models have sufficient baseline knowledge; roles mainly affect tone and style.

"roles do not help with any accuracy-based tasks whatsoever"

Multiple perspectives yield more reliable answers.

Generate answers using varied prompts or models, then select the most common response as final output.

Why: Reduces impact of individual model biases or errors through statistical aggregation.

"take the answer that comes back most commonly"

AI systems remain vulnerable to adversarial prompts.

Attackers use creative techniques like storytelling, typos, or encoding to bypass safety filters and elicit harmful outputs.

Why: Current safety measures are brittle against novel prompt injection strategies.
