Thousands of reviews, summarized into themes by AI. The promise is real, and so are the ways it quietly misleads. Here is the honest version.
The cost of a token: how model pricing works
"Model bills are measured in tokens, not words or requests. Understanding what a token is, and which ones you pay for, is how you keep costs predictable."
Retrieval-augmented generation (RAG), from first principles
RAG is often explained as a stack of tools. Strip that away and it is one simple idea: let the model read the right material before it answers. Here is how it really works.
Streaming responses: why and how it helps UX
Streaming does not make a model faster — it makes the wait feel shorter. Here is why that matters and what it costs you to build.

AI coding assistants all demo beautifully. Here is a framework for judging them on the things that actually matter to your day-to-day work.
Catastrophic forgetting and continual learning
Teach a neural network something new and it tends to forget what it knew. This stubborn problem is why models learn in big batches, not in a stream.
Chain-of-thought: why reasoning steps help
Asking a model to "think step by step" makes it noticeably better at hard problems. That is strange if you think about it. Here is why it works.
Test your prompts like code
A prompt is code that ships to users. Treat it that way — with test cases, a baseline, and a regression check before every change.
Data licensing: the real constraint behind AI products
The hardest part of many AI products is not the model — it is whether you are allowed to use the data at all. A plain-language tour of the constraint that quietly decides what gets built.

AI moderation scales to volumes humans never could — but every dial you turn trades one harm for another. Here are the tradeoffs you cannot escape.
Personalization with AI without creeping people out
AI makes personalization cheap and precise — which is exactly why it can feel invasive. Here is how to be relevant without crossing the line.
Multimodal models: what "it can see" really means
When a model "sees" an image, it is not looking the way you do. Here is how multimodal models actually work, what that enables, and where they quietly fail.
Distillation: teaching small models from big ones
Knowledge distillation trains a small model to imitate a large one. The trick is not copying answers, but copying the way the big model is unsure.

Set up a feedback loop to improve answers
An AI feature that never learns from its mistakes stays stuck. How to capture signal, turn it into examples, and close the loop that makes answers better.
Evaluation beyond benchmarks: human and model judges
Benchmarks measure what is easy to score. For open-ended work you need judgment — from people, or from a model standing in for them. Both can mislead.

A language model that makes things up is not malfunctioning — it is doing exactly what it was built to do. Here is why hallucination happens and how to manage it.
Synthetic data: training models on model output
When real data runs short, models can generate their own training data. It is powerful, slightly circular, and dangerous if you forget where it came from.

Examples teach a model faster than instructions. Here is how to choose, order, and format them so few-shot prompting reliably pays off.
Why two runs of the same prompt differ
"Send the same prompt twice and you often get two different answers. That is by design, not a bug — and knowing why tells you when to control it."
Regulation of AI: the broad shape
AI regulation looks like chaos up close, but it has a recognizable shape. A durable map of the approaches, tensions, and ideas that keep recurring.
