# AI999X Labs

> AI999X Labs builds self-improving intelligence and releases open models. The Future Is Self-Improving.

AI999X models are small, fast and run offline on an ordinary CPU, installable from PyPI and published on Hugging Face and GitHub. Each model answers in its own field with step-by-step working, units and formulas, and says so plainly when a question is outside what it can answer.

## Models

- [mechanics-ai999x](https://www.ai999x.com/models/mechanics-ai999x/): mechanics-ai999x answers classical mechanics questions — damped, driven and coupled oscillations, physical and double pendulums, orbits and escape speed, moments of inertia, rolling, Atwood machines, precession…
- [algebra-ai999x](https://www.ai999x.com/models/algebra-ai999x/): algebra-ai999x solves linear, quadratic, cubic and quartic equations, systems, inequalities, logarithms, sequences and matrices, and writes proofs — with step-by-step working and LaTeX. It runs offline on any CPU as a…
- [physics-ai999x](https://www.ai999x.com/models/physics-ai999x/): physics-ai999x answers physics questions written in everyday language — kinematics, forces, energy, momentum, rotation, waves, fluids, thermodynamics, electricity, magnetism and optics — with step-by-step working, units…
- [ai999x-encoder](https://www.ai999x.com/models/ai999x-encoder/): ai999x-encoder reads a question written in plain English and finds which AI999X capability it is about — a formula, a procedure or a law — across every AI999X model at once. At 4.9 MB it runs offline on any CPU and…
