Zai AI is a powerful, user-friendly AI chatbot and intelligent agent that brings advanced artificial intelligence right to your fingertips. Built on the latest GLM-5 and GLM-4.7 large language models, it handles everything from quick questions and brainstorming sessions to more creative and technical tasks like generating landing pages, creating slide decks, analyzing datasets, building simple 3D models, or even prototyping mini games and personal blogs.
Is Zai AI Free or Paid?
Zai AI is primarily free. The core web-based chatbot and agent features are available at no cost, giving users generous access to its full range of capabilities without requiring payment or a subscription for everyday use.
This free tier is ideal for most individuals and light professional needs. For developers and power users who want deeper integration with popular coding environments (such as Cursor, Claude Code, Cline, or Kilo Code) and significantly higher usage limits, Zai AI offers optional paid GLM Coding Plans. These plans unlock priority performance, expanded quotas, and specialized tools while keeping the experience affordable compared to many Western competitors.

Zai AI keeps its pricing straightforward and value-packed, with flexible billing options (monthly, quarterly with 10% savings, or yearly with 30% savings). The paid plans focus on coding and agentic workflows, while the basic web chat remains free.
