What Is Z AI and How It Works
A free chat on Z.ai's own GLM models, with a strong lean toward code
Z.ai is the company behind the GLM models, and chat.z.ai is its free browser chat, running GLM-5.3-Flash by default.
Besides answering questions, it builds things from a prompt: landing pages, teaching material, mini games and personal blogs.
Every answer comes from Z.ai's own GLM models. They are strong at code, and Z.ai sells a separate GLM Coding Plan for coding tools.
What the chat does not have is a GPT, Claude or Grok model in the same window for a second opinion.
People who want to compare answers from different AI companies, or make images and video next to the chat, start looking elsewhere.
Someone searching for a Z AI alternative free of charge usually wants the same quick chat, plus more models and more tools.
Introducing n33: Free All-in-One AI Platform
A disclosure first: N33 is our product. It is a browser AI chat with GPT, Claude and Grok models, plus a Studio for images, video from text or a picture, talking avatars and dubbing into 13 languages. If you want to compare more options than these two, our ChatGPT alternatives page covers the wider field.
Free AI tools that compete with Z AI: Claude Haiku 4.5, GPT-5.6 Luna and Grok 4.5 are free without an account. GPT-5.6 Terra and Sol, GPT-6 Astra, GPT-5.5, Claude Sonnet 5, Claude Opus 5, Grok 4.6 and Grok 4.7 use energy, which a free account gets (some to start, more to claim every day). For drafts and rewrites, the AI writer page shows prompts that work well with them.
Where Z.ai stays stronger: coding inside your own tools. Its paid GLM Coding Plan starts at $18 a month and plugs GLM models into Claude Code, Cline and OpenCode; N33 is a browser chat and Studio, not a coding plan.
Where N33 adds something: pictures and clips next to the chat. The AI image generator makes a picture from a text prompt for a little energy, and the AI video generator makes a 5 to 12 second clip from text for more energy, both with a free account.
Cost Calculator: Z AI vs n33
Z.ai's browser chat is free. Its paid GLM Coding Plan, for coding tools such as Claude Code and Cline, starts at $18 a month (Z.ai docs, September 2026). Pick a preset or type what you pay; n33 starts at $0, since the free models need no subscription.
