Fundamentals
8 articlesThe basics: how models work and why.
What is Vibecoding?
Vibecoding means coding by describing what you want to an AI and accepting its output without reading it closely. Good for fast exploration, not for production.
What are Hallucinations in LLMs?
Hallucinations occur when an LLM generates false or fabricated information presented with apparent veracity, without intent to deceive.
What is Multimodality in Artificial Intelligence?
Multimodality enables a model to process and generate multiple data types simultaneously: text, images, audio, video.
What Is Prompt Caching?
Prompt caching stores the attention computation (K/V) for a stable prefix across calls so it isn't recalculated — it cuts latency and cost, but breaks if you switch models.
What is an LLM
A language model trained on massive text to predict and generate coherent language — the engine behind ChatGPT, Claude, and Gemini.
What is the Context Window?
The context window is a language model's immediate memory. Understanding it is key to avoiding incomplete or incoherent responses.
What is AI-First Development?
AI-First is a development paradigm where the human directs technical decisions and AI executes the mechanical work, inverting the traditional workflow.
What is a token
A token is the text unit a model processes. It shapes input splitting, context limits, latency, and usually API cost.
