# Zhipu AI: GLM models

GLM is the family of models from the Chinese company Zhipu AI (Z.ai) — open, inexpensive, strong in code and agent work. How to connect them in SKILLOK.

## Who they are

**Zhipu AI** (the **Z.ai** brand) is a Chinese company that releases the **GLM** models. Many of them are open and among the strongest open models for programming.

## Models

* **GLM** — the flagship model and its lighter versions (`Air`, `Flash`).
* Models that understand images.

The exact list and versions change often — current models are visible in the list when you connect a key in SKILLOK, and in the [model catalog](https://skillok.org/docs/en/ai-models/models).

## What they are good at

* Strong code and agent work.
* Open weights, low prices, some models have free versions.

## Access from Russia

The easiest way is through an intermediary.
