About

Idle.py

Features
Read full description

Idle.py — a Python tutorial disguised as an idle game. Learn Python and modern AI engineering by playing. Tap to generate FLOPs (floating-point operations), then spend them on Compute Units that keep earning while you're away. Every Compute Unit you unlock — from your first variable to an AGI Lab — ships with a hand-written lesson, code samples, a quick-check quiz, and a 50-question practice bank. Real coding lessons. Real curriculum. No filler. THE COMPUTE UNIT LADDER • Variable, Function, Class, Module — Python's atoms. • Tensor, Neuron, Layer — what every model is built from. • Attention Head, Transformer Block — the 2017 idea that ate AI. • Foundation Model, Agent — pretraining, fine-tuning, tool-using LLMs. • GPU Cluster — distributed training: DDP, tensor parallelism, pipeline parallelism, NCCL. • AGI Lab — the recursive endgame. PYTHON PROGRAMMING BASICS (always free, always on) Lists & Tuples Ā· Dicts & Sets Ā· Strings & f-strings Ā· Control Flow Ā· Comprehensions Ā· Iterators & Generators Ā· Decorators Ā· Exception Handling. PRACTICE BANKS Every lesson has 50 questions. Correct +1 knowledge, wrong āˆ’1 — drift below a bucket and your bonus drops. Option order reshuffles every draw, so you learn the answer, not the position. THREE REWARD AXES • Mastery (+1% per level) — earned from quizzes, capped at three per Compute Unit. • Knowledge (flat FLOPs/sec bonus) — earned from practice banks. • Insight (compounding multiplier) — earned from retraining the run. AI LANDMARKS 27 lifetime-FLOP milestones from "Hello, World" through GPT-4 and beyond. Each grants a permanent tap multiplier. The history of artificial intelligence is your scoreboard. TRANSCENDENCE (hardcore loop) Stack ten GPU Clusters and you can transcend: wipe the run for a permanent global multiplier and one Transcendence Unit (TU). Spend TU to unlock Singularity and ASI — the loop above the loop. NO ADS. NO SUBSCRIPTIONS. Optional one-time purchases only: • Founder Pack — permanent Ɨ2 multiplier on FLOPs and tap. • Mentor Pack — advanced curriculum (LoRA, RLHF, Mixture of Experts, Evals). • Time skips and insight packs as small consumables. WHO IT'S FOR • Beginners who want a more rewarding Python tutorial than another video course. • Engineers picking up the modern AI engineering stack from the ground up. • Anyone who wants their idle game to teach them something real. Idle.py respects your time. Progress saves automatically. Offline FLOPs are credited on launch. No popup ads. No timers built to wear you down. Just the curriculum, the loop, and the math.
