From tokens to agents, the atlas of AI.

Beginner Fundamentals

Artificial Intelligence

The broad field of building machines that mimic human-like learning, reasoning, and decision-making.

Beginner Machine Learning · Core

Machine Learning

Letting computers learn patterns from data instead of being explicitly programmed.

Beginner LLM & Language Models

LLM

A massive AI model trained on huge text corpora that learns to predict the next token and can hold conversations.

Advanced LLM & Language Models

Transformer

The neural-network architecture behind modern LLMs that learns how much each word should attend to every other word.

Intermediate Vectors

Embedding

A vector representation that captures the meaning of text, images, or audio.

Intermediate RAG & Search

RAG

Query → document retrieval → LLM context injection → answer generation.

Advanced Agents & Protocols

MCP

An open protocol that lets AI applications connect to external data sources and tools in a standardized way.

Advanced Agents & Protocols

AI Agent

An autonomous system that uses an LLM as its brain to call tools, plan, and reach a goal step by step.

Beginner Prompting

Prompt

The input text you give an LLM — its quality largely determines the quality of the answer.

Chat Cost Calculator Estimate the monthly cost of your usage by model and token flow.

GPU Calculator Model size + quant → how much VRAM you need, which GPUs fit.

Model Recommender Pick a use case + priority → ranked top 5 model suggestions.

Token Calculator Estimate how many tokens your text uses, and how much of a model's context window it fills.

Throughput Estimator Concurrent users + model → estimated TPS and number of GPUs.
