What is Zhipu AI?

Zhipu AI is a Chinese AI company that develops the GLM (General Language Model) series. Its flagship product is a consumer chatbot at chatglm.cn, plus developer APIs and enterprise models.

Its core promise:

• Free access — a generous free tier for everyday use
• Strong reasoning — competitive on math, logic, and coding benchmarks
• Native Chinese fluency — excellent for Chinese writing and translation
• Developer APIs — build apps on top of the GLM models

For anyone curious about the Chinese AI landscape, Zhipu is one of the “big four” AI labs in China alongside the companies behind Qwen, DeepSeek, and Moonshot (Kimi).

How Zhipu AI works

The GLM chatbot works like other modern assistants:

1. Open the chat — at chatglm.cn, no heavy setup.
2. Ask anything — questions, code, documents, or writing tasks.
3. GLM responds — with reasoning, code, or drafted text.
4. Refine the conversation — iterate like any chat assistant.

What makes GLM notable is how much performance you get on the free tier — the gap between GLM’s public models and the top Western models has narrowed dramatically.

Key features of Zhipu AI

GLM’s strong reasoning

GLM models score competitively on math, logic, and reasoning benchmarks — the kind of tasks that separate capable assistants from toy chatbots.

Free everyday assistant

The free tier covers chatting, writing, and coding for regular use, with paid plans unlocking higher limits and faster models.

Native Chinese excellence

GLM is first-class in Chinese — writing, translating, and understanding Chinese context better than most Western models, which matters for a huge share of the world’s users.

Developer API

Zhipu offers APIs for the GLM models, so businesses can integrate the assistant into their own products without training a model from scratch.

Multi-model choice

Zhipu releases multiple model sizes, from lightweight fast models to flagship reasoning models, letting users pick the right balance of speed and capability.

Zhipu AI vs. ChatGPT vs. DeepSeek

	Zhipu GLM	ChatGPT	DeepSeek
Free tier	✅ Generous	Limited	✅ Generous
Reasoning strength	✅ Strong	✅ Strong	✅ Strong
Chinese fluency	🏆 Native	Good	Native
Western ecosystem	Limited	✅ Largest	Limited
Developer API	✅ Yes	✅ Yes	✅ Yes

Zhipu is the strongest choice for Chinese-language work and a free, capable general assistant. ChatGPT wins on ecosystem and integrations. DeepSeek is its closest Chinese rival on raw reasoning. For most users, GLM’s free tier is more than enough.

Who is Zhipu AI for?

• Curious users wanting a free, strong AI assistant.
• Chinese speakers needing native-language writing and translation.
• Developers building on GLM’s API.
• Researchers comparing the global AI landscape.

It’s not for teams that require Western data residency, or users whose primary need is image/video generation — those are better served by dedicated tools.

How to get started with Zhipu AI

1. Open chatglm.cn — the GLM chatbot.
2. Sign up free — an account unlocks the full free tier.
3. Ask your first question — try a reasoning puzzle or a coding task.
4. Explore the API — if you’re a developer, check Zhipu’s model API docs.
5. Upgrade if needed — paid plans add speed and limits.

Start with a hard reasoning or coding question — that’s where GLM surprises people.

The bottom line

Zhipu AI is proof that the most interesting AI competition is now global. GLM gives you a free, genuinely capable assistant with best-in-class Chinese fluency — and it’s worth adding to your list of assistants to compare, whether you’re a curious user or a developer building on its API.
